Radiofrequency communication device comprising a timer

摘要

The device (1) has an interrupter (6) permitting a radiofrequency operation of the device over an activation of the interrupter and stopping the operation after releasing the activation of the interrupter. A timer circuit (7) maintains a continuous radiofrequency operation of the device for a period that is equal to a period of an electronic transaction to be performed e.g. bank payment transaction, after the activation of the interrupter. The timer circuit is provided with a static electronic interrupter (8) i.e. transistor.
