Abstract:
An apparatus for determining the validity of an encoded check adapted to operate a metering device comprises means for accepting the encoded check. Decoding means decode the check and provide a check code responsive signal. Additionally, the apparatus includes subscriber operated code means to provide a subscriber identifying code signal. Computer means check for correlation of these signals and also are programmed to check credit data. If the computer means determines authenticity, a signal is provided to check storage and dispensing means for issuing a new check which in character and nature is substantially identical with the accepted check, except for encoding. Prior to rendering the check available to a subscriber, the new issued check is encoded for causing it to be operable with a predetermined metering device. In the alternative embodiment, the same check accepted is re-encoded and rendered available to the subscriber.
