ABSTRACT:
An electronic cash register employing a price-look-up table includes a detachable recording medium for recording item codes and the corresponding item prices, and a reader for reading the data from the detachable recording medium. During a transaction operation, the recording medium is checked to determine whether it is connected to the reader, and, if it is, the detachable recording medium is searched for an item involved in the transaction operation. If that item is present on the detachable recording medium a transaction operation based on the medium-recorded prices for that item, rather than a previously stored price for that item, is carried out.
