A point of sale device, in which no money tendered or received by a customer is touched by the operator, comprises a note handling device with viewing windows 20 to enable the operator to check the authenticity of the tendered notes, a keyboard 14, which includes keys for accepting and rejecting tendered notes, and a prompting display (38, Fig. 2 not shown) which assists the operator in determining the selling price of an item within one of a set of categories: By indicating numerical codes corresponding to items to be sold the prompting display permits sales of a relatively large number of different items to be covered by a relatively small number of keys. <IMAGE> |
