Portable transaction-log recorder

Abstract

An improved apparatus for the recording of credit card transactions at point of sale, and for reporting said transactions to a central accounting and processing activity. The instant invention includes a self contained, compact, portable and lightweight cassette-like transaction log recorder which is adapted to be releasably and operatively engageable with an imprinter mechanism. The recorder contains both an external duplicate sales ticket and an internal continuous form log sheet for the sequential recording of individual transactions at the time various data is applied to successive sales tickets. The recorder is also provided with external receiving means for receiving the customer's credit card at a receiving station, means for translating the card from the receiving station to an imprinting station, means for latching the card immovably at the imprinting station to an external removing station. The recorder is further provided with a safety interlock system which prevents the human error of recording two discrete transactions on the same portion of the log sheet. This interlock system includes means for effectively disabling the card latching means until the log sheet is deliberately incrementally advanced, thereby displacing the record of the previous transaction from the imprint station and presenting an unused portion of the log sheet for recording of the next sequential transaction. Unless the card latching means is operative, no imprinting can occur.
