A credit method and system including a plurality of individual, separated credit stations each provided with a magnetic tape having credit information, such as the numbers of invalid cards. A central station periodically, for instance once each night, transmits, preferably by frequency modulated radio waves, updating credit information to the credit stations, which replace the information on their tape with the updating information. To check a card, it is first presented to a credit station where credit information coded in or on the card in magnetic ink or otherwise is compared with information on the tape. In addition, a voice pattern on the card can be compared with the voice pattern of the person presenting the card at the station as derived from his enunciation of a code word or phrase. If the card is accepted, the transaction is preferably manually entered into and displayed at the credit station before being stored, preferably at a plurality of locations, on another magnetic tape.
