Apple Lossless Audio CODEC (ALAC), implemented a fingerprint reader in iPhone 5S during 2013, allowing users to secure their iPhone terminals both for unlocking and for purchasing applications from App Store. If you have a terminal with fingerprint reader, touch ID, and have you ever wondered if he can be heard while running, well it seems that this is possible. According to some users with a lot of time at their disposal, the fingerprint reader of the iPhone 5S can be heard during operation, more precisely when we place our finger on it for scanning.
To be able to listen to your sensor touch ID i shall to go to a place where absolutely no noise can be heard and bring the door of the prison with the fingerprint reader closer to your ear. Next, you have to place your finger on the Home button, after the terminal has been unlocked and the scanning actions of your fingerprint should generate a series of very weak sounds. For everything to work, you need complete silence and clean ears, but don't expect to hear anything other than a series of extremely fast clicks when you place your finger on the reader.
The idea itself is not an extraordinary one and you will certainly not amaze anyone if you tell that you listened to Touch ID while it was working, but at least you know that this is now possible.
