Apparatus and method to facilitate shopping
Abstract
Abstract A recorder for use by shoppers in a self-service store, having three sets of key banks for recording three groups of symbols, such as numerals, appearing on each item selected for purchase by the buyer. The recorder includes a mechanical verifier for determining the accuracy of the entries made in the recorder. The indicia appearing on each purchased item includes a coded number which, combined with the other two numbers of the indicia, must equal a predetermined total for the information to be recorded in the machine, and for restoring the keyboard to a condition ready to accept indicia appearing on the next purchased item. One of the other two numbers represents the price of the selected item while the other number represents the weight in ounces. When the indicia from all of the items selected for purchase are properly entered and totaled in the recorder, if the total weight of the selected items is correct, then the total price will be correct and may be paid by the customer without further checking or tallying of the purchases.
