A system for managing electronic receipts is provided. According to one aspect, the system includes a portable device, a base device, a user device and an electronic receipts administration system. The electronic receipts administration system provides the base device with the appropriate data to allow the base device to generate, store and manage electronic receipts accordingly. A user uses the portable device to conduct a transaction with the base device. The base device uses a variety of information to generate an electronic receipt for the transaction. Such information includes, for example, information stored on the portable device, information stored locally on the base device and information stored on another device such as an electronic cash register. The electronic receipt is then stored on the portable device. The user device allows the user to subsequently retrieve the electronic receipt for management purposes.

PROBLEM TO BE SOLVED: To surely prevent leakage of important information by changing the way to encipher a registered user password at each time to reduce the probability that the registered user password is deciphered by the third person as much as possible in the case that a server device preliminarily enciphers and writes the user password of a user who is permitted to use a DB card, and register it when writing a DB file in the DB card. SOLUTION: When writing the DB file in a DB card 3, a server device 1 enciphers the user password with a time variable changing at each time as the key and registers it in the DB card. A portable terminal device 2 acquires the time variable key from the card when accessing the DB card and enciphers a password inputted by an operator by this time variable key to collate the password; and when the operator is an authorized user, the device 2 permits access to the DB file in the card.
