We recommend that you use the SureFlap Microchip Pet Door or Cat Door with your pet's veterinary inserted microchip. However if your pet is not microchipped, the SureFlap RFID collar tag is available as an alternative. SureFlap RFID collar tags contain a code that is unique to your pet so that if other pets in the neighbourhood have a SureFlap collar tag, or any other type of collar tag used in selective pet doors, they will not be able to gain access through your SureFlap Microchip Pet Door or Cat Door. SureFlap RFID collar tags are compatible with all versions of the SureFlap Microchip Pet Door and with the most recent version of the SureFlap Microchip Cat Door (serial numbers higher than 1152201). One collar tag is supplied with the SureFlap Microchip Pet Door, but you may need to purchase additional collar tags if you have more than one non-microchipped pet. The SureFlap Microchip Cat Door does not come supplied with a collar tag. This pack contains two collar tags.
