The games token (1) has an integrated electronic data substrate with a processor (11), store (12) and aerial (15) for transmitting r.f. signals (20), surrounded by an electromagnetically transparent housing section (2). The store contains permanent and uncopiable master data (14). To the token is allocated a decentralised, autonomous write-read station WR by means of which information can be read out from and written into the data substrate MI, which is initialised by an authorisation system. At every identification process the write-read station WR generates new initialisation data (21) which are transmitted to the data substrate MI, linked there with a code (22), returned to the write-read station and decoded and examined there. This provides a trully unforgeable games token which can be used in any kind of games installation and ensures trouble-free play.
