What password can be called the most reliable and at the same time constantly accessible to the owner of the equipment? Fingerprint. IN new development 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.
Unlock button iPad mini 3 is made of sapphire crystal, 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 carries out 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:
- Response speed and minimal amount necessary 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 :
- Before starting the process, thoroughly wipe the button and fingers.
- 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).
- 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.
- 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 the sensor as an account identifier, 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 actions for Touch activation ID on iPhone 5s, iPhone 6 Plus with iOS 8 and updated iPhone 6 free application 1Password:
- Open “Settings” (tab located on the bottom panel of the program).
- Select the “Security” section.
- Scroll to the tab with the name of the technology.
- 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 functionality, 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.
Fingerprint sensor finger touch ID on a fairly recent iPhone does not always work when touched and you have to constantly enter the password? If you are faced with similar problem, then in this material we will tell you how to fix it.
In contact with
Everyone knows that after purchasing a new iPhone, it is necessary to complete the activation procedure and initial setup of the device, which includes setting up the Touch ID fingerprint sensor built into the Home button. The user is asked to add a fingerprint with which the iPhone can be unlocked.
From our many years of observations of users setting up new iPhone, we can say with confidence that adding a fingerprint to Touch ID during the initial setup of the device is often done very quickly and not always with an understanding of the process. Most users hold their iPhone in a completely different way when setting up the biometric sensor. normal use. This is where the whole secret lies.
Moreover, after initial setup Few people return to iPhone Touch options ID (in iOS settings) to continue the process of improving sensor performance. As a result, users continue to use the only fingerprint that was recorded in Touch ID the first time setting up iPhone. But in the sensor parameters you can add as many as 5 prints. So…
Touch ID doesn't work well on iPhone: how to properly set up the fingerprint sensor on iPhone or iPad
1 . Open the Settings app on your iPhone or iPad and go to Touch ID & Passcode.
2 . Enter your passcode.
3 . Remove any added fingerprints. To do this, select each fingerprint and click Delete fingerprint.
4 . Click Add a fingerprint.
5 . Hold your iPhone or iPad the same way you would normally hold the device before unlocking it.
6 . Go through the process of adding all five fingerprints this way:
- add your fingerprint twice Thumb right hand ;
- add your fingerprint twice Left thumb;
- add your fingerprint once Index finger right hand(if you are right-handed) or left hand (if you are left-handed).
The point of this operation is to add more fingerprints to the most used unlock option. 
The scheme we have proposed can be changed if desired. For example, if you always unlock the device with one hand, then it wouldn’t hurt to add Thumb 3, 4 or even all 5 possible fingerprints.
Try it now. In the vast majority of cases, this will solve the problem of poor Touch ID performance.
If, after completing the procedure for adding fingerprints, the sensor still does not respond well, try rebooting the device. If the reboot does not help, then there are two options left - either you are the owner of hands with an abnormal fingerprint structure (we have met such users) or the problem is still in the Touch ID sensor itself.
Touch ID is a technology that first appeared in the iPhone 5S, used as additional parameter operating room safety iOS systems and a means of user identification. The essence of this technology is that a special biometric sensor is built into the Home button, which allows you to read the user’s fingerprints and use them instead of a password to access the phone, as well as to make purchases in the App Store and iTunes Store.
As mentioned above, Touch ID was first introduced in the iPhone 5S, but it is expected that this year the biometric sensor will appear in new iPad Air and iPad mini, and, of course, in the new iPhone generation, which is expected to appear in the second half of 2014. At the same time, most likely, the new devices will also use a new generation of the Touch ID 2 sensor with improved recognition technology and, possibly, support for additional functions.

To make recognition of the finger used to unlock the device more accurate, you can do the following: assign the same fingerprint to different memory slots. That is, in essence, you need to “scan” one finger several times, as if they were different fingers. Thus, the accuracy of your fingerprint recognition can increase to almost 100%!
2. Keep the Home button clean so that it is free from dust or moisture. The accuracy of fingerprint recognition directly depends on the surface of the sensor, so, naturally, if there is grease, dust or dirt on it, the accuracy of fingerprint recognition is noticeably reduced.
3. Check that you have installed it on your device latest version software- Apple may program level make changes and improvements to the built-in iOS functions. For example, in version iOS 7.1.1, Touch ID improvements were officially made, thanks to which fingerprint recognition became more accurate and smooth.
After updating the software, we recommend that you delete all registered fingerprints and add them again to make Touch work ID is as accurate and convenient as possible.

Let me remind you that Touch ID is great way using a fingerprint instead of the usual four-digit password. One press of the Home button is enough to unlock your iPhone, let's figure out how to set up Touch ID.
How to set up Touch ID
Apple says Touch ID can recognize your finger from almost any angle. This is true; when you initially scan your fingerprint, the phone will ask you to re-send your finger to the sensor for additional scanning from different angles and angles.- To begin with we need activate Touch ID, we go along the following path:
- Settings - General - Touch ID and password - Touch ID
- Once Touch ID is enabled, iPhone will require you to enter the usual four-digit passcode to provide additional security. For example, when adding other fingerprints.
- Now you need to gently touch the “Home” button until you feel a slight vibration. This action must be repeated as many times as necessary. In this case, the fingerprint image will gradually fill in. It is important to do everything as if you were using an iPhone in Everyday life, that is, as natural as possible. Make sure your finger and button are dry.
- At some point, the phone will ask you to touch the button at an angle with your finger to scan the edges of your fingertip.
- after rebooting the phone;
- available in the “Touch ID and Password” settings section;
- after 48 hours have passed since the last unlock.
What can you use Touch ID for?

Touch ID doesn't work
If you encounter problems when working with Tocuh ID, the reasons may be very different. Apple recommends all sorts of triviality in such cases - make sure that you have the latest iOS version, the “Home” button is not covered with dirt, pay attention to whether your entire finger covers the sensor and stuff like that...If all of the above is not the case in your case, then we can recommend trying to register a different fingerprint.
Problem still exists? Your case is the worst. Apparently you are faced with a manufacturing defect in Touch ID. Most often this is accompanied by the error " Scanning failed, please go back and try again" when performing a fingerprint scan and if reboot iPhone did not help you, then you need to take the phone to the service center.
The most disgusting thing about this problem is that sometimes it is the seller's fault. The fact is that if there is a defect, unscrupulous sellers assemble two iPhones into one, and since the Touch ID sensor is connected to the native processor, they cannot find each other in the body of one phone. This is just one of possible reasons, you should not assume only this, but such an option is quite possible.
What to do if Touch ID doesn't work well
Often iPhone users and iPad complain about poor Touch ID performance. Moreover, difficulties with fingerprint recognition can arise even with the button cleaned of dirt and dust and clean, dry fingers.Few people know, but iOS has a built-in function for correcting your fingerprint data. In other words, the accuracy of Touch ID recognition can be improved and it’s not difficult at all:
- Go to: Settings – General – Touch ID and password – Touch ID;
- register multiple fingerprints if you have not already done so;
