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.
Claims13
An electronic cashless system comprising:
- a terminal device;
- and
- a center device connected to said terminal device;
- said terminal device including
- first communicating means for communicating with said center device a first amount information to be subtracted from an account in said center device, said first communicating means annexing an account information with said first amount information;
- and
- means for storing said first amount information into a memory;
- and
- said center device including:
- deposit ledger file means for identifying and storing account balances of multiple accounts, account by account;
- non-settled fund file means for storing a non-settled fund which is an accumulated value of said first amount information, without specifying an account of said first amount information, at each time which said first amount information is subtracted from said account in said center device;
- and
- processor means in response to said first amount information communicated with said terminal device, for subtracting said first amount information from said account specified by said annexed account information, and for renewing said non-settled fund in said non-settled fund file means by adding, without annexing said account information, said first amount information which is subtracted from said account by said processor means.

An electronic cashless system comprising:
- a commercial transaction terminal device;
- and
- a center device connected to said terminal device;
- said commercial transaction terminal device including:
- means for inputting a commercial transaction amount information;
- tallying file means for memorizing said commercial transaction amount;
- and
- means for notifying said commercial transaction amount information to said center device and for storing said commercial transaction amount into said tallying file;
- and
- said center device including:
- deposit ledger file means for identifying and storing account balances of multiple accounts, account by account;
- non-settled fund file means for storing a non-settled fund which is a value of accumulating a first amount information, without specifying an account of said first amount information, at each time which said first amount information is subtracted from an account in said center device;
- and
- processor means in response to said commercial transaction amount information communicated with said terminal device, for renewing said non-settled fund in said non-settled fund file means by subtracting said commercial transaction amount information from said non-settled fund.

An electronic cashless system comprising:
- a center device having a file storing a plurality of accounts and an account balance for each account;
- and
- a cashless medium which is communicatable with said center device through a line and which is portable by a user;
- said cashless medium including:
- first communicating means for communicating with said center device a first amount information to be subtracted from an account of said user in said center device;
- a first memory storing a second amount information corresponding to a cash amount which is held by said user;
- and
- means for obtaining a total amount information by adding said first amount information to said second information and storing said total amount information into said first memory;
- and
- said center device including:
- deposit ledger file means for identifying and storing account balances of multiple accounts, account by account;
- non-settled fund file means for storing a non-settled fund which is an accumulated value of said first amount information, without specifying an account of said first amount information, at each time which said first amount information is subtracted from an account in said center device;
- and
- processor means in response to said first amount information communicated with said cashless medium, for subtracting said first amount information from said account specified by an annexed account information, for obtaining a renewed non-settled fund in said non-settled fund file means by adding, without annexing the account information, said first amount information to said non-settled fund stored in said non-settled fund file means, and for storing said renewed non-settled fund into said non-settled fund file means.
