System and method for electronically interchanging values

A system and method where a value sender's values are managed on central servers. On the central server, a separate value credit line for offline transfers is managed in a value account associated with the sender by virtue of the corresponding value credit optionally being reserved for the credit line in the sender account. During an online connection, the value credit still available which is stored on an intelligent device and also the values demanded by the receiver are communicated to the server. The value sender's value account on the server is reduced by the value sum used. During an online connection, the server transmits the arranged credit line to the read/write unit. A transmitted credit line is stored on the intelligent device as available value credit. For offline transactions, the available value credit on the device is reduced by the values transmitted to the receiver.
