The microchip is computer readable and lasts indefinitely as it doesn't need a battery to operate. Each microchip has a unique ID number that is put onto a central database together with your address details. SureFlap is compatible with all the following types of microchip commonly used for pets:
15-digit microchips (also known as FDXB)
Most 10-digit microchips (also known as FDXA)
9-digit microchips (also known as Avid Secure/Encrypted Chip)
If your cat becomes lost then all vets and re-homing centres are equipped with a special scanner to read the microchip. They can simply look up the ID number on the database and give you a call to return your cat.
