Abstract: A device adapted to be activated when a consumable portion card with consumable unit portions is inserted therein, the insertion of said card and other articles being blocked by a gate operable if a valid consumable portion or unit still remains on said card, the card taking the place of a coin. The device can be used to operate a bed vibrator, turn on a radio or television for a predetermined time, or activate other types of devices hitherto started or operable by coin-operated mechanisms.
