Abstract

In recent years, the banking business has developed rapidly, and the traditional business also gradually transferred to the electronic automation. The ATM is one of the most successful example, so the study of ATM control system has very important practical significance. To this, the design based on single chip microcomputer (STC89C53) as control core, through the 4 * 4 matrix keyboards, and button simulation daily operation such as withdrawal, displaying in LCD12864 . By using the function of the 24C02 reservoir to avoid data loss. This system can realize simulation card authentication password input, withdrawals, query, change and some functions which are necessary for ATM to own. This paper provides improvement resources and classic cases for the real ATM, which will make it more convenient for the public. 

This paper has 17 figures, 2 tables and 9 references.
