The company explained that all the information gathered by the Touch ID is stored in a chip located inside the A7 chip.

They claim the chip can’t be accessed even if someone exploits the new 64-bit processor on the smartphone.

iMore decided to swap the fingerprint readers between two iPhone 5S in order to check on that.

The A7 chips eventually recognized the fingerprint reader that was shipped with it from the factory, showing errors of recognition for a reader from another device.

The findings demonstrate that the fingerprint reader enhances the security level of the Touch ID as no one can exploit the system.
