The present invention relates to a handling system for information carriers such as credit cards (1) and the like, including information storing means such as chip circuits (4) and the like. The essence of the invention resides in the feature that a credit card, when not used, is to be unserviceable. To activate a credit card to serviceable condition there is introduced into the chip circuit, by a code transmitter (Fig. 3), one or more states of authority, which are adapted to be read by a transceiver device (28) included in a press copying machine for credit cards (18, Fig. 4). The authority information received is arranged to be indicated (35) at the press copying machine. The press copying operation is also arranged to control the transceiver device (28) such that a signal is transferred to the chip circuit (4-6) to extinguish the state therein, that is, to deactivate the credit card after authority indication. |
