Apple provides users of its technology with a large number of functions designed to ensure complete security and protect the device from unauthorized persons. One such add-on is Touch ID.

What is Touch ID

Touch ID is a password that can be set to unlock the device or access certain applications. Unlike previous passwords, which were a combination of numbers or a key character, Touch ID checks the fingerprints of the person trying to unlock the phone or tablet and compares them with the fingerprints stored in the device's memory. If they match, then the unlocking is successful, but if Touch ID suspects that they are trying to hack the device, it will go into lock mode. The user has three attempts to prove their identity using unique fingerprints.

The advantage of this technology is that it is the most reliable way to block access to your device or individual programs. If a phone or tablet is stolen, it will be very difficult for an attacker to remove it from the locked state.

Touch ID first appeared on the iPhone 5S and is present on all subsequent phone models. This technology is also available on iPad Air 2 and iPad mini 3.

How to enable, disable and configure Touch ID on iPhone

Before activating Touch ID, it is recommended that you restart your device, close all applications and wash your hands, since the first time you turn it on you will need to add your fingerprints, and if they are unclear, you may have problems unlocking the device in the future.

1. Open the Settings application.
2. Go to the “Touch ID and Passcode” section.
3. Click the “Add fingerprint” button. The device screen will show detailed instructions to add a fingerprint. It will be necessary to apply your finger several times, raising and lowering it at the right moment. Hold the device the way you normally hold it. Don't place your finger straight or at a certain angle; place it on the Home button the way you most often place it during everyday use.
4. If you think that the fingerprint is inaccurate, then find it in the “Fingerprints” block and swipe it from right to left. A “Delete” button will appear, which you must click to erase the fingerprint.
5. You can click on the name of the resulting fingerprint to assign any other name.
6. Now we activate the “Unlock iPhone” function if you want the device to unlock only after touching it with your finger.
7. Activate the iTunes Store feature App Store" if you want your fingerprint to be required when entering a store.
8. If you want to disable Touch ID technology on your device, then deactivate the two features above.

What to do if a function stops working or crashes

Some users experience problems immediately after enabling Touch ID, while others experience problems after a few days or months. The problem may be the following: Touch ID does not work, has stopped working, does not work the first time, does not work correctly. To get rid of all the above problems, you need to do the following:

1. Reboot your device by pressing the Lock and Home buttons at the same time for 8-10 seconds.
2. Open the Settings app.
3. Go to the Touch ID and Passcode section.
4. Delete any existing prints. To do this, first click on the name or fingerprint number.
5. In the tab that opens, click the “Delete fingerprint” button. Repeat this operation with all prints.
6. Click the Add Fingerprint button. Follow all instructions that appear on the device screen: remove and reapply your finger, rest the tip or middle of your finger, rotate, and others. Repeat this process with each finger.

If restoring fingerprints does not help fix problems with Touch ID, you need to take the device to a service center to get advice from a qualified specialist and possibly send the device for repair, since the problem is most likely in the hardware of the phone or tablet. If you hacked the firmware of your device using Jailbreak, then this may be the reason. Also the reason may be IOS version, must be installed on your device latest version firmware so that Touch ID works correctly.

By changing the design one by one, improving performance and demonstrating new interesting features and technologies that ensure comfortable use of the phone. However, it was difficult and very difficult for engineers, designers and other equally important employees of the Cupertino company to invent a new design for the iPhone every year. This is how a permanent model appeared in the line of Apple smartphones with the prefix “S” at the end (and later “C”). These phones were practically no different from their predecessors from last year in appearance, but surpassed them in power and other parameters that are so important for many geeks.

In addition to the above, the improved iPhone models had a certain “trick” - a function or technology that stimulated people to buy. The 4S had it, which performed the role of a voice assistant quite well, although from the very beginning it could only communicate in English, and the iPhone 5S proudly demonstrated an innovative fingerprint scanner Touch ID, allowing you to put reliable protection on your smartphone from unnecessary eyes and hands, but is fingerprint scanning technology really that important and what negative and positive aspects does it entail? I will try to thoroughly understand all this in this article.

How it all started or who was the first to use an analogue of Touch ID

iPhone 5S on at the moment demonstrates excellent work with recognizing your fingerprints to protect data, but it is worth mentioning and telling who was the first to use the mentioned technology and experienced all the pitfalls of the mobile device market.

The pioneer was the South Korean company Pantech, which introduced a new model back in 2004 cell phone, referred to as Gl100. The phone at that time had a fairly high-quality screen and camera, but unlike other devices, it had a fingerprint scanner, which allowed you to hide numbers and other information.

The scanner was located directly at the top of the screen in the middle of the navigation buttons (up, down, left, etc.). To recognize a fingerprint, the average user needed to move his finger across the surface of the scanner at an average speed for an accurate result. According to assurances this operation should have lasted 3-4 seconds, but harsh practice has shown that unlocking the phone with your finger took a considerable 14-15 seconds, so the use of revolutionary technology brought ordinary users much more discomfort than convenience. Also, throwing stones towards the Pantech Gl100, I will mention that all hidden information in the phone could also be copied by synchronizing with a computer. This was one of the first attempts to introduce fingerprint recognition technology into mobile device.

Later and others no less well-known companies implemented an analogue of Touch ID into their devices, but ended up encountering multiple technical problems and malfunctions. It seemed that over time the idea had completely outlived its usefulness and the market no longer needed devices with a fingerprint scanner, but Apple suddenly changed the situation.

The emergence of Touch ID

Rumors about the introduction of Touch ID appeared on the Internet long before the release itself. I tried hard not to believe it. Pantech’s attempt is firmly entrenched in my memory, but despite all my skepticism, the guys from Cupertino still presented the iPhone 5S, which had a much more powerful processor, an improved camera, a coprocessor, and most importantly, an excellent fingerprint scanner. Right at the presentation, they showed us how easy and convenient it is to use the new Touch ID, how it will make it easier for us to use our smartphone, and how we used to live without it, but put all this rotten sarcasm aside and let’s talk about the facts.

At the time of release, users could add several fingerprints to the iPhone 5S database at once to solve family issues. It is unlikely that anyone will be pleased when their child comes up every minute asking them to unlock their phone; there are many similar situations. Functionally, the scanner allowed you to unlock your smartphone using your finger, as well as link your fingerprint to , which made it possible not to enter your account password every time you purchase an application or other media content from the AppStore.

In addition to all of the above, the iPhone will be guaranteed to be protected in the event of its possible theft or loss - all your data will be protected. On this note, the list of Touch ID features ends. By comparison, Siri had a lot more functionality when the 4S was released. Yes, they did not understand and still do not understand the great and mighty Russian, however voice assistant could launch an application, find a restaurant nearby, talk about the upcoming weather and more, and the basics of Siri are already used in cars under iOS control Car, but back to the main thing...

Touch ID and surveillance paranoia

Quite often there were rumors and theories on the Internet that Apple was deliberately conducting covert surveillance of users through mobile gadgets and more, and many of these guesses were completely confirmed. What comes to mind is the news about tracking iPhone location coordinates and the sudden activation of the iSight camera on Mac computers.

The iPhone 5S suffered the same fate, and literally after a while bloggers began to claim that the Apple company scans users’ fingerprints and transfers them to intelligence agencies. Without hesitation, Tim Cook replied that all fingerprint data is stored inside the Touch ID itself and cannot be copied - this is a completely obvious answer. After all, for the CEO of a multibillion-dollar company, it is important to appease his clients and instill in them a sense of security. It is unlikely that any of you will be able to imagine how Tim Cook at the next presentation or interview says: " Yes, we are carefully monitoring you and all your fingerprints have already been sent to the intelligence services to be entered into a special database. Good luck everyone and buy ours new iPhone 5S".

I’m leaning towards the option of possible surveillance by Apple. After all, very recent events in the world hint at precisely such methods of fighting terrorism for our own protection. It is worth remembering how, just last year, the FBI carefully pursued a group of people involved in the terrorist attack in Boston, with the help of the almighty Facebook.

It’s time to put everything in its place - yes, we are being watched, yes, many of us don’t care, however, looking at this whole situation, you are imbued with a certain irony. Where is the notorious protection of the iPhone, when the intelligence services are stealing our data right in front of our noses and whether the introduction of a fingerprint scanner was a deliberate move on the part of the same law enforcement services, but this is already too loud a theory and should be put aside.

Touch ID and security

If we talk about security, Touch ID shows amazing results. Constantly scanning your fingerprint with different sides, over time, a more accurate picture is created, allowing you to recognize your finger even better. At the same time, the probability that someone in the world has a separate part of the fingerprint can coincide with yours is approximately 1 in 50,000, when the chance of guessing the password is 1 in 10,000.

It is practically impossible to hack Touch ID, copy too. The fact is that your fingerprint is stored as an encrypted mathematical formula. In addition to encryption, a special unique key is also required to access the fingerprint; only the native processor of the device knows it (Secure Enclave technology). In other words, if you change the processor or sensor, they will not see each other, since they will not be located within the same iPhone.

Let's summarize. The iPhone 5S turned out to be really powerful, beautiful and interesting in terms of technology, but the introduced Touch ID turned out to be a very controversial innovation and as a result raised many unanswered questions online - are our fingerprints being stolen, how will the technology revolutionize iOS itself, should we wait for a sensor to analyze the retina, saliva, hair, and so on... In reality, users only got the opportunity to unlock the smartphone and avoid entering a password, which already costs a lot.

If you have not found an answer to your question or something has not worked out for you, and there is no suitable solution in the comments below, ask a question through our

What password can be called the most reliable and at the same time constantly accessible to the owner of the equipment? Fingerprint. The new Touch ID uses a fingerprint sensor as a means of identification. This method allows you to quickly or otherwise Apple devices and at the same time be confident in the security of the stored data.

Of course, the question immediately arises: Touch ID - what is it? The device itself, the technology or, in general, the phone model? Apple Touch ID is a technology that involves the use of a sensor that recognizes the user's unique fingerprint pattern. The unlocking process is simple: just place your finger on the Home button. The installed sensor reads the received data from absolutely any angle and in any way the iPad is positioned.

The iPad mini 3 unlock button is made of sapphire glass, which is enclosed in a stainless steel ring. Each part: the ring detects touch, and the glass part transmits fingerprint data to the sensor. The reading program performs a comparative analysis and signals compliance. It is noteworthy that the Touch ID sensor performs the entire operation within a fraction of a second.

Advantages of the technology:

• Speed ​​of response and minimum number of required operations.
• Security of confidential information (thanks to the specific architecture of the A7 processor).
• Information security user (the password and fingerprint used cannot be copied or transferred in any way, and is also not available to the OS and applications).
• Authorization in applications (Touch ID technology is already integrated to simplify the process of confirming actions or signing).
• Using a fingerprint, you can confirm the purchase and iTunes - using Touch ID technology will eliminate the need to enter payment data and passwords.

How to enable and configure Touch ID?

Unfortunately, it is not yet possible to put a single checkmark to implement the functions of the technology. Then a logical question arises: how to enable Touch ID?

Initial setup

First of all, you should deal with the initial setup. She :

1. Before starting the process, thoroughly wipe the button and fingers.
2. Enter a four-digit password that you have created, which the program will use without recognizing the fingerprint (the request is also possible after a reboot, two days after the last unlocking of the device, or to access functions).
3. Holding the device as if you normally press “Home”, place your finger on the button (a light touch is enough) and hold it until there is a slight vibration or until the system signals that you can remove your finger.
4. After the initial recognition is completed, the system asks you to change the position of the pad - this is necessary to complete the scanning. Now you need to attach the edges of the fingertip.

If the device is activated, then the initial setup can be done through the main menu: by going to “Settings”, select “Touch ID and password”, then “Fingerprints”. The system itself will offer to go through the described registration process and about fingerprints.

Activation methods

If you can't set up Touch ID, you can use the sensor for purchases and password entry. To unlock an iPhone using technology, simply wake it up from sleep mode by pressing the “Power” or “Home” buttons, and then place your finger on the “Home” button. To use a sensor as an identifier account, you need to go to the settings section, then select “Touch ID and password” and activate “iTunes Store, App Store”. When downloading content, the system will inform you that you need a fingerprint on your iPad or other device.

Authorization using a scanner is activated separately, in the settings. Below are the relevant steps to activate Touch ID on iPhone 5s, iPhone 6 Plus with iOS 8 and updated iPhone 6 free application 1Password:

1. Open “Settings” (tab located on the bottom panel of the program).
2. Select the “Security” section.
3. Scroll to the tab with the name of the technology.
4. Switch the toggle switch to the “On” position.

Now the entrance to the program is available after pressing the fingertip against the sensor for a second!

Non-working function: defective or improper operation?

Undoubtedly, but what should you do if Touch ID stops working or does not work initially? There may be several reasons for this:

• Household reasons (incomplete coverage of the button with a fingertip, contamination of the sensor, and even others). It should be noted that most of the complaints about Touch ID not working well fall precisely under this and the next category.
• Just a glitch in the recognition program. In this case, it is better to register a different fingerprint.
• There is, unfortunately, such an option as marriage. An indicator of such a situation is the lack of effect from rebooting the device and a scanning error. Moreover, it doesn’t matter whether the defect was made at the production stage or by a rogue seller who assembled one iPhone out of two without taking into account the binding of the Touch ID sensor to “its” processor, the phone will still have to be taken to a service center.

With customization of the action, the functions in each application are more than covered by convenience, speed of operation and optimization of purchasing processes. Although the possibility of a marriage that could bring trouble cannot be ruled out.

Apple has been successfully using the Touch ID biometric sensor in its devices for several years to protect users’ personal data. To prevent this system from malfunctioning during operation, we have prepared some practical tips for you.

The Touch ID fingerprint scanning system has become one of the main features of the iPhone 5S and still delights users of phones and tablets from the Apple company. Using your fingerprint, you can unlock your phone, pay in the App Store or iTunes, and recently the biometric sensor works in conjunction with Apple Pay and other applications, including those from third-party developers.

From time to time, Touch ID users encountered minor problems - smartphones refused to recognize their fingerprints. For some time, the reason was, which Apple promptly corrected. However, this was not the only problem.

With all the reliability and modernity of the biometric sensor in the iPhone 5S/6/6 Plus smartphones, as well as in iPad tablets Air 2 and new iPad Mini 3, periodically, and this miracle of technology fails. We decided to figure out why problems with recognizing the owner’s fingerprint may arise and how they can be eliminated.

When turning on and setting up Touch ID for the first time, the smartphone prompts the user to place a finger on the sensor several times and does this for a reason. The thing is that when using a smartphone, you do not place your finger at a right angle, or your finger may not be completely clean, wet, and so on. The system specifically asks you to move your finger over the surface of the reading sensor when setting it up. However, even this standard procedure, designed by Apple to improve Touch works ID does not always save users.

Therefore, inquisitive minds around the world quickly came up with a simple and fairly reliable way to improve and speed up the operation of the biometric sensor in Apple technology on their own. To make Touch ID recognize your fingers faster and more accurately, simply make several copies of the same fingerprint. Touch ID allows you to add up to five fingerprints, and even if you've added both thumbs and index fingers to the database, you'll still have one free slot where you can add a copy of the fingerprint you think you'll use more often. Thanks to this simple operation, the accuracy of Touch ID increases by 60-90%, in proportion to the number of copies of one fingerprint.

Another simple way to improve the performance of a biometric sensor is the so-called. To do this, you need to go to the security settings, enter your password and simply alternately place your fingers entered into the sensor base. At the same time, the system determines which fingerprint you are currently “training” by highlighting it in gray. If you do this procedure for each fingerprint several times in a row, the accuracy and performance of Touch ID will increase.

When entering your fingerprints into the phone's memory, try to do it as naturally as possible, as if you were picking up the phone in order to unlock it or do some other familiar action, and not to send a perfect copy of your fingerprint to the CIA.

If the Touch ID sensor remembers data about your fingerprints under field conditions as close as possible, then it will perceive them in real life much better. Therefore, feel free to place your finger on the biometric sensor in a way that is convenient for you, at any angle. The stability of your fingerprint perception and the accuracy of Touch ID will only benefit from this.

A small but practical tip for Touch ID users: touch the metal edge of the Home button with your finger when scanning your fingerprint. In this way, the sensor will receive from you the most complete picture of the identification fingerprint and will be able to more accurately and quickly recognize the “finger” offered to it.

Well, last but not least, advice to Touch ID users. Perhaps the most banal and obvious, but at the same time important - wash your hands and keep the Home button itself with the sensor located in it clean. If you're having trouble identifying your fingerprint, start by simply wiping the front of your phone and the button itself.

The layer of dust and grease that accumulates on the surface of the biometric sensor, which is invariably present on our fingertips, makes it difficult for Touch ID to properly scan your finger. Therefore, do not hesitate to wipe the button more often, and keep your hands clean, this will be useful not only for Touch ID, but also for your health.

Every user of Apple smartphones and tablets equipped with a fingerprint scanner will agree with me that it takes some getting used to this new feature it was not difficult - it is so harmonious, simple and convenient. For example, I’m so used to Touch ID that when I pick up an iPod Touch, I just hold my finger on the Home button for a while and wait for the player to unlock, without thinking at all that there’s something missing in this device . Apple were not pioneers, but their solution was so successful, convenient and elegant that people instantly got used to Touch ID and now look puzzled at Apple devices that lack this function.

This is why it is very important for users that their biometric sensor works correctly, quickly and accurately. And we hope that with our advice this will be exactly the case.

Greetings! The article is dedicated to the upcoming New Year holidays, and at any other time, I think the information will be quite relevant and useful. Why did this instruction appear at all? The thing is that now on the market there are simply a lot of offers for selling iPhone with a non-working Apple ID fingerprint sensor. No, seriously, not only the entire Internet is littered with such devices, but also numerous “real” points of sale.

And the best thing about this whole situation is the price. Oh yes! Everything is very good here. After all, for such a seemingly insignificant malfunction (and a non-functioning scanner is a breakdown), a fairly large discount is offered on the iPhone itself. Why not take it? Let's figure out together why you don't need to take it...

What usually sells:

1. iPhone (any model) with a non-functional fingerprint scanner.
2. The price for it is less (sometimes significantly) than for a similar product only with a functioning sensor.
3. The seller assures that this is a new and absolutely normal iPhone - it’s just refurbished (REF).

And because of the third point, confusion begins, because many have heard that Apple is releasing refurbished devices onto the market. And this is true, only they have nothing to do with an iPhone with a broken finger sensor...

iPhone without Touch ID - officially refurbished device or not?

No, no and no again. Officially refurbished iPhones, the so-called “like new” ones, are fully functional devices. Everything works for them - from the battery to the notorious fingerprint sensor. They are produced at the Apple factory, tested, have a one-year warranty (and it is two years) and are supplied through official sales channels to dealers for sale. In general, everything is “OK” with them. I have already written about such devices - there are a lot of interesting things in the comments directly on the topic of this article.

Important! On a new original, real, factory (call it what you want) iPhone, the fingerprint sensor will always work. Always. If during the sale it is stated that the device is new and from the factory, but the scanner does not work, they are lying to you.

But iPhones without Touch ID (also supposedly officially restored) are a completely different story. Where, and most importantly, what are they collected from? It’s very difficult to find out specifically and for certain, but I’ll tell you in general terms now.

iPhone with a non-working scanner - what is it and where does it come from?

So, we found out that such devices are not produced by Apple, so where do they come from? Everything is very simple, these are ordinary used gadgets, only assembled from several devices. So to speak, “restored” by various craftsmen. A little more detail, using an example:

You have several iPhones with different breakdowns - the display of one does not work, the second is completely flooded with water, the third is fine, “only” motherboard broke. You take all three, combine them, buy spare parts from the Chinese - you have a “refurbished” iPhone.

It is clear that options are possible, but in general terms this is exactly what it looks like.

Why is the fingerprint scanner not working on these iPhones, is it difficult for the Chinese to fix it? Yes, it’s hard, and this is due to this:

The motherboard and the Home button (where the sensor is located) for one specific iPhone (the official one coming out of the factory) are a single whole. If you substitute a button from another phone, the sensor stops working. This is done so that no one can hack your iPhone simply by connecting another button to it. Safety and protection come first!

This connection can only be “broken” at the Apple factory, which is what they do when producing officially refurbished iPhones - where, I repeat, absolutely everything works.

Pros and cons of an iPhone with a broken Touch ID – can you buy it?

If you have not yet decided whether to buy such a device or not, then here is a list of the positive and negative aspects of such an event. Let's start with the cons. So, if the scanner does not work, it means:

• What exactly the iPhone was disassembled is unknown by whom and how.
• It is also assembled from something unknown - spare parts can be either original or “Chinese”.
• Considering the two previous points, even if everything works in it now (except for the sensor), it is still a time bomb - any component of such an iPhone can malfunction at any time and stop working.
• Inability to use Apple services based on a fingerprint (the same Apple Pay). And in general, the security of your personal data is at great risk.

Are there any advantages? Yes, there are two of them:

• Price – the cost of an iPhone with a defective scanner is always less (otherwise who will buy them?).
• You may be lucky and come across a successful device (more likely no than yes).

I hope that now everyone should have the right opinion about the advisability of buying an iPhone with a non-functioning Touch ID sensor. If it doesn’t work out, then I’ll give you a hint: buying such a device is a very big lottery with a minimal chance of winning, but with a huge opportunity to simply throw away money.

Updated! As I wrote, buying an iPhone without Touch ID is a big gamble. In my opinion there is no point in playing it. Moreover, you can save money when buying a normal iPhone. How? Instructions:

1. Among the stores you know, we find one where the price of an iPhone is cheaper and the refund on your purchase is higher.
2. Victory.

That's all - enjoy the phone and the money saved.

P.S. Agree that the information is useful - like the article, do a good deed :) And of course, write your questions in the comments. I will answer everyone!
