Abstract

An electronic label device includes a display device and a microcomputer connected to control the display device. The microcomputer includes a memory having a plurality of registers. Data received via an antenna is stored in the registers. The microcomputer is indirectly controlled to selectively display data stored in the registers on said display device. The indirect control is effected by coupling signals to the said microcomputer without physical contact with elements of the label device, such as by a magnetic reed switch, capacitor coupling or inductive coupling.
