    摘要： Disclosed is a tamper resistant PIN entry apparatus for input of a key and for encryption of a password in a cash transaction machine. The PIN entry apparatus supplies the electric power to a memory of an electric circuit section, in such a manner that a first rod and a second rod of a rear case connect contacts of a key scan board, wherein the first rod is protruded on the rear of a key module including a button provided substantially on the front of the key module and the second rod of the rear case is coupled with the rear of the key module. At this time, in case that the rear case is removed from the key module or damaged, thereby changing the location of any one of the first and the second rods at the contact, the electric circuit section detects the event and destroys the memory itself physically. Otherwise, the electric circuit section makes information stored in the memory physically or softwarely unreadable, thereby preventing the leakage of the information.
