To provide a method of securing the entry and verification of a PIN.

There are provided an apparatus and methods for encrypting an identifier such as a PIN entered on a keypad. The apparatus may include a pad, an encrypting circuit adjacent to the pad and a link coupling the pad and the encrypting circuit. The pad is for entering an identifier, and the circuit is for encrypting the entered identifier. The pad may be a physical touch pad such as an N-wire-technology touch pad. Alternatively, the pad may be a virtual touch screen. The encrypting circuit may be a CPU along with a memory coupled to the CPU and programmed to encrypt. The CPU and programmed memory may be the first CPU programmable to encrypt the entered identifier, through which the identifier passes. The encrypting circuit may be a microcontroller programmed to encrypt.
