(1) the keyboard of a client is usually composed of three parts: a 16 key keyboard and a two - 4 key keyboard. The 16 key keyboard is a function key for the customer's input amount and "confirm", "Cancel", "correct". The 4 key keyboard is usually installed on both sides of the CRT display screen to allow the customer to choose a transaction project.

(2) encryption module has two ways to use. If it is used alone, its function is to encode and decrypt the encrypted data of communication when ATM is communicating with the bank host.
