Abstract
A system for exchanging data between a portable payment terminal and a stationary base terminal in communication with a payment center. The portable terminal and the base terminal each include a central unit and a radio transmit-receive module. Each central unit is adapted to generate/read binary messages transmitted/received in the form of radio waves by the transmit-receive module. The portable payment terminal or the stationary base terminal include means for storing the binary messages and means for deactivating the central unit such that the radio transmit-receive module is operable only when the central unit is deactivated.
