Abstract
An electronic weighing instrument includes an IC card reading and writing device. An IC card is inserted into the IC card reading and writing device, and as a commodity to be weighed is designated by inputting, a price per unit weight of the designated commodity preset in the IC card is read out. A price of the commodity is calculated from the price per unit weight and a weight of the commodity obtained from a digital signal developed from a load detector, and the weight and the price are indicated on a display unit while a code, the weight, the price per unit weight and the price of the commodity are registered into a registration memory of the IC card. Where a plurality of such weighing instruments are installed, there is no need of provision of a cable interconnecting the weighing instruments. Further, since prices per unit weight of commodities are stored in the IC card, the capacity of the memory required for each weighing instrument can be minimized.
