The Swing-Microchip cat flap features a special antenna that reads and recognizes your cat's microchip, unlocking the door as your pet approaches. It can store up to 32 standard ISO 11784 microchips and has been specifically designed and tested for worldwide use. Storing the microchip code is simple and quick: bring your cat to the door from the outside and press the corresponding memory button to save the code. The Swing-Microchip can be installed in wooden and glass doors or walls. This model, like the other Swing doors, includes a windstopper system and a special 4-way opening system: you can choose whether to let your cat in and out, only in, only out, or completely lock the door. This cat flap also features a convenient passage indicator: a small plastic flag shows whether your pet is inside or outside. The Swing-Microchip is battery-operated and has a low battery indicator. When changing the batteries, the stored data remains fully intact. If your cat does not have an implanted microchip, you can use the included collar with an integrated chip. For cleaning, simply wipe the door with a soft, dry cloth from time to time, as well as the sensors inside the tunnel on the right and left of the door.
