How does SureFlap^TM know my cat's microchip number?

When SureFlap^TM is put in learn mode then the door is unlocked. The next cat to go through the flap has its microchip read and the code put in memory, permanently. Your cat will now be recognised by SureFlap^TM.

Using this learn mode you don't have to force an uncooperative cat through the flap. Just leave SureFlap^TM in learn mode and let him go through in his own good time... Simply repeat this process with multiple cats.
