The invention relates to the field of transmitting series of data between electronic circuits, and more specifically a method and a system for transmitting series of data, from a first electronic circuit to at least one second electronic circuit, via an electrical connection line between the first circuit and the second circuit, in reference to a ground line common to the circuits, of at least one series of data pulses. Each data pulse makes it possible to both electrically supply the second circuit and to transmit an item of data which can be interpreted by the second circuit. The supplying of the second circuit by the first circuit is cut between two successive pulses. For each data pulse and before the second circuit is switched off, because of failure in supply, the item of data transmitted by the pulse is stored on a non-volatile memory support of the second circuit.

Method and system for transmitting data sets

A device comprising a physical support and an electronic chip supported by the support and comprising a memory module and a processor configured to implement a computer program configured to produce a result from data. The device further comprises a display module configured to display the result and a radio antenna configured to receive at least one electromagnetic signal configured to electrically supply the display module. The data comprises at least one item of static data, stored in a non-transient memory and an item of dynamic data, circulating in a transient memory. The dynamic data is received by the device through the at least one electromagnetic signal and the at least one electromagnetic signal is received by the device from at least one communication device.
