Abstract

An RFID tag in a receptacle is active and includes a microprocessor, a data storage device operable to store a selected code (e.g. an ID code to identify said object or said product), the object including a display for displaying the aforesaid selected code upon a signal from the microprocessor and an energy storage device (e.g. a lithium ion battery), operable to energize the microprocessor, the display, and the transmitter. The tag has an antenna having a dimension thereof that is substantially as large as to a maximum dimension of receptacle.
