Abstract
A security system, particularly useful in an electronic funds transfer system, makes use of secret identification codes known only to system users. The codes are encrypted upon insertion into the system and are stored in a data processing unit in encrypted form. A security module is used to decrypt the code entered by a user and compare it to the corresponding encrypted code stored in the data processing unit.
