♦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.
