Abstract
Abstract An information carrying card has an EPROM device. Individual steps of a manufacturing or inventory scheme are operated using the card. Information can be added to or deleted from the card by a central processing unit or a local read/write device. The information carrying device need not be a card and it can constitute or include an EEPROM or an equivalent device.
