(1) customer keyboard
The keyboard is usually made up of three parts: a keyboard with 16 keys and two keyboards with 4 keys. The 16 key keyboard is a function key used to enter the amount of money for customers, and has the functions of "confirm", "Cancel" and "correct". The 4 key keyboard is usually installed on both sides of the CRT display screen so that customers can choose transaction items.
(2) encryption module
There are two ways of using this module. If it is used alone, its function is to encrypt and decode the data of the communication when the ATM is communicating with the bank host. If it is used together with the client keyboard, it can encrypt all the information entered by the customer besides the above functions.
