ABSTRACT:
A combination timepiece and electro-optic identification code device employs elements of the timekeeping display and has a programmable read only memory (PROM) storing a number of identification codes with means for selecting the code and transmitting it from the memory via an electro-optic display portion on the timekeeping display to an opto-electronic reader placed in proximity with the timepiece. The code selected may be unique to the device itself, may be selected by the user, and be a machine-readable code representative of the time, or may be a combination of any of the above codes.
