Abstract (en)
[origin: ES8304345A1] The indentification system consists of a key comprising a passive memory area (10) and a shift register (9) and a lock which can be coupled with the key. The lock is capable of supplying a set number of pulses causing the code contained in the memory (10) to be loaded into the register (9). The register (9) is subdivided into a certain number of elements linked together but loaded independently. This loading is carried out successively by the multiplexer (111). Transmission of an incorrect number of loading pulses leads, through connection (113), to a modification of the contents of the shift register (9).
