PROGRAMMER FOR IDENTIFICATION SYSTEM Abstract of the Disclosure A tag has a memory programmable to store alphanumeric indications in a pattern identifying an object associated with the tag. The stored indications are convertible to signals transmitted to a displaced reader in an individual pattern at first and second frequencies to identify the object. The memory may be programmed, during the production of a first logic level in a signal on a program pin, (a) by the operation of keys on a keyboard in a programmer housing, each key representing an individual alphanumeric character, or (b) from an external source such as a typewriter keyboard used in conjunction with the programmer. The signal on the program pin has a second logic level to provide for bulk erasing all particular memory positions. A configuration signal has a first logic level providing for the alphanumeric coding of the memory and a second logic level providing for the selection, at particular memory positions, of individual capacitors to generate signals at the first and second frequencies. When the programming signal has the second logic level and the configuration signal has the first logic level, bulk information may be erased from the memory. Dependent upon the logic levels of the programming and configuration signals, (1) information is programmed in the memory, (2) the capacitors are selected or (3) programmed information is bulk erased when an energizing pin in the programmer receives a particular voltage. A detent on the tag has a plurality of pads for introducing the different logic levels to the programming, configuration and energizing pads in the tag. This detent mates with a detent in the programmer housing to provide for the introduction of the programming, configuration and energizing signals to the tag through the pads in the tag detent,
