♦Ibutton Principle
when unlocking, the electronic control system will verify whether those 64 bits binary
code in the TM cards is same with the existing password. If it is same, the door will
be unlocked, if not the same, the door will not be unlocked. In this condition, the door
lock will alarm when the mistakes occur continuously, that is to say, there are
2^64 times different binary code in the chip of TM cards.
