Found a simple way to improve the accuracy of recognition fingerprint Touch ID




Some users of iPhone 5s, iPhone and iPhone 6 6 Plus complain about poor performance fingerprint scanner built into the main button of the smartphone. Web developer Josh Betts found an easy way to “exercise┬╗ Touch ID.


In iOS 8 has built-in corrections introduced biometric finger prints without the need to rescan.

“To start your workout, go to Settings -> Touch ID and password – says Betts. – Enter the password to change the biometric sensor. Now touch your finger to the scanner Touch ID registered in the finger. You will see that for a few seconds the desired mark is highlighted in gray. Now, to improve detection and scanning speed, continue to deal with the same finger to the sensor in other states, “- explains the developer.

Biometric sensor Touch ID has become one of the main functions of the smartphone iPhone. Scanner, built-in button Home, with a thickness of 170 microns (about twice as thick as a human hair) analyzes subepidermal layers of the skin and provides images with a resolution – 500 ppi. The owner of the phone can teach Touch ID to identify a few fingers, and touch sensor can be arbitrarily – finger orientation does not matter.


To improve recognition accuracy Touch ID finger fit enough to repeat the procedure a web developer several times. There is no need “from scratch” to rescan the desired mark.
