RFID (Radio Frequency Identification) is the wireless use of electromagnetic fields to transfer data through microchips, that carry electronically stored information about the animal.
To read the info contained in the microchip, it is necessary to use an RFID reader that, positioned near to the animal’s skin, transmits a low-power radio signal through its antenna to the microchip to power wirelessly its integrated circuit and get its data.
Microchip scanning is now standard practice for animal control agencies, shelters and most veterinary clinics in North America, Europe and Australia for all pets that are brought in as lost or stray. Microchip scanning is also gaining momentum in Asia and Africa. Having a microchip for identification significantly increases your pet’s chances of being returned to if he or she is ever lost or stolen.
