Microchipping offers positive identification of dogs and cats without undue expense or cruelty. The technique is already accepted as positive identification for traded dogs and cats. Universal scanners that can detect all microchips have been available in Britain for some years.
Portable readers permit scanning almost anywhere.
The ISO has approved a standard frequency for all brands of microchips intended for use in pet identification. Many UK locations already have readers. Pet identification chips have no moving parts or internal power supply. Except when vitalized by radio beams from a compatible scanner, they remain completely inactive. At least 34 billion unique identification codes are available.
