Patent attributes
A pin-pad and pin-pad security method are provided. The pin-pad includes: a keypad module including a plurality of buttons; a main board comprising an encryption circuit configured to encrypt a key signal input from the keypad module; a first flexible circuit board to protect an upper portion of the main board; a second flexible circuit board to surround a side surface of the main board; a double cover to block access to a circuit in the main board; and an information blocking circuit unit configured to erase information stored therein to block leakage of the information when disconnection or a short-circuit of an electric circuit is detected from at least one of the main board and the first and second flexible circuit boards. When the pin-pad is disassembled or cut, information stored in an internal memory is erased to block leakage of the information remaining in the internal memory.
