First Claim
Patent Images
1. A cashless medium card, comprising:
- an external interface for receiving from an adding terminal device a transferred charging amount of money to be added to the cashless medium card and from a subtracting terminal a first purchase amount to be subtracted from the cashless medium card;
a memory storing a second amount corresponding to a current cash balance, the current balance initially being the transferred charging amount; and
a processor coupled to said interface and said memory, which operates within a cashless system without requiring an identity of a holder, subtracting the first amount from the second amount to determine a remaining amount representing available cash of the holder of said cashless medium card and for storing the remaining amount as a renewed second amount in said memory and said interface transferring the first amount from the cashless medium card to the subtracting terminal device.

Abstract
An electronic cashless system uses a cashless medium for memorizing amount information and for performing an operation of amount information. The electronic cashless system comprises an automatic transaction terminal device having a reading/writing unit for writing amount information to the cashless medium, and a center device having a unit for identifying the account balance of multiple accounts and for storing amount information and a non-settled fund file unit for storing amount information written by the cashless medium and a seller ledger file means for identifying the account balance of the multiple seller'"'"'s accounts and for storing amount information.

2. A cashless medium card, comprising:
-
electronic storage storing a current cash balance of said cashless medium card; and a transaction unit interfacing with external terminal devices to change the current cash balance without using an identity of a holder of said cashless medium card, the transaction unit of the cashless medium card, in a charging operation, transferring a first transferred amount of money from one of the external terminal devices to said storage and adding the first transferred amount to the current cash balance and, in a purchase operation, the transaction unit of the cashless medium card, transferring a second amount of money from said storage to another one of the external terminal devices and subtracting the second amount from the current cash balance.

4. A cashless medium card, comprising:
-
a memory storing a current cash balance; an external interface transferring, in a charging operation, from a first terminal device a first amount of money to said memory changing the current cash balance of said cashless medium card and transferring, in a purchase operation, a second amount of money from said memory to a second terminal device and changing the current cash balance of said cashless medium card; and a processor coupled to said interface and said memory, operating with the second terminal device without requiring an identity of a holder of said cashless medium card, changing the current cash balance by the second amount to determine a remaining amount representing available cash of the holder of said cashless medium card and storing the remaining amount in said memory as an updated current cash balance. - View Dependent Claims (5, 6)
