RFID devices (also known as microchips or transponders) come in a variety of types which are not all compatible.  Currently, transponders only store their unique identification number. Their use must be complemented by a reliable and available database which links this number to the owner and details of the animal carrying the transponder. The information in this database must be kept up to date and accessible.

Implantable microchips are about the size of a grain of rice, and in companion animals are implanted under the skin, just forward of the shoulder blades. The microchip contains a unique identification code, which is registered in our database along with the animal and owner information.
