Have you ever wondered how a cat flap with chip recognition works?The problem with conventional cat flaps is that they can also allow uninvited guests such as strange cats or small animals to enter.
A cat flap with chip recognition uses a sensor that recognizes the cat's microchip and thus only grants access to your pet.
In this article, you will learn everything about how a cat flap with chip recognition works, its advantages and how to install it, so that only your cat can come and go whenever it wants.
Technical basics of the cat flap with chip recognition
A cat flap with chip recognition allows only your cat to have access to your home. The secret behind it is radio frequency identification technology, or RFID for short. This technology uses electromagnetic fields to transmit data that recognizes your cat's implanted chip. This keeps the door closed to uninvited guests.
The way it works is extremely simple but effective. Your cat's chip contains a unique identification number. When your cat approaches the flap, the cat flap sensor reads this chip and decides whether to open the door or not. This enables selective access control without the need for physical contact.
Power supply of the cat flap: An overview
The power supply of the cat flap and the transponder is crucial for their functionality. The transponder, i.e. the chip, does not require its own power source. Instead, the necessary energy is provided by the cat flap reader. This is done by an electromagnetic field that is activated when the cat approaches and reads the chip. The cat flap itself is either connected directly to the power supply or powered by batteries to ensure constant operational readiness.
Access control through chip recognition: How it works

Access control through chip recognition is based on the identification of the cat's implanted chip. As soon as the chip comes into the reception range of the cat flap sensor, the sensor reads the chip's unique identification number. Access is only granted if this number is stored in the flap's system. This ensures that only authorized cats are allowed in and that the home remains protected from unwanted guests.
The need for a cat flap with chip recognition
A cat flap with chip recognition is a necessity for cat owners for several reasons. Especially if your cat is an outdoor cat, you want to make sure that it can come and go safely at any time. Such a flap offers your cat freedom and you as the owner the certainty that only your animal has access. This is especially important to keep out unwanted guests such as strange cats or wild animals.
The need also arises from the need for comfort and security. With a cat flap with chip recognition:
- Can you sleep peacefully without getting up to open the door for your cat.
- Protect your home from the intrusion of other animals.
- Make sure your cat has access to her home whenever she wants.
Overall, such a cat flap offers comfort not only for the cat itself, but also for the pet owner.
Advantages of a cat flap with chip recognition
A cat flap with chip recognition offers clear advantages over conventional models. The biggest advantage is probably the selective access control . Only cats that have a registered microchip can pass through the flap. This means that your cat has free access at all times, while unfamiliar animals have to stay outside. This function is particularly useful if you live in an area where there are a lot of cats.
In addition to security from strange animals, a cat flap with chip recognition offers other advantages:
- Avoid stress for your cat as it does not have to fight with strange animals for its territory.
- Protect your home from the intrusion of foreign animals that could cause damage or transmit diseases.
- Convenience for the owner as manual door opening is no longer necessary.
Overall, a microchip cat flap provides more safety, hygiene and convenience in the everyday life of cat owners.

The best installation location for your cat flap

Choosing the best place to install your cat flap is crucial to making it easier for your cat to access while protecting your home. Ideally, you'll want a location that's easily accessible to your cat and where the flap won't be exposed to the elements . This could be a door to the garden, a side wall that's not directly exposed to the elements, or even a basement window if your cat is used to taking that route.
You should also consider installing the flap in a slightly elevated location , as cats prefer to survey their territory from an elevated position before entering or leaving it. A small platform or staircase in front of the flap can help with this. Also make sure that the installation location is not too close to your living area to minimize drafts and the entry of cold.
Tunnel extension for microchip cat flaps: A guide

If you want to install your microchip cat flap in a thicker wall, a tunnel extension is necessary. These extensions are designed to simply be plugged onto the existing tunnel of the flap to achieve the required length. For each extension, the tunnel thickness increases by 50 mm, allowing you to adapt the flap perfectly to the wall thickness .
The installation adapter: your helper during installation
The installation adapter is an essential accessory for installing your cat flap in various materials such as glass, thick walls or metal doors. It not only makes installation easier, but also ensures that the flap is held securely . The use of the adapter is particularly important when installing in glass, as there are special requirements for stability and tightness here.
The Key to the Microchip Cat Flap: How It Works
The key to the microchip cat flap works by detecting your cat's unique microchip. When the cat approaches the flap, the sensor reads the chip and only allows your cat access , while other animals must stay outside. Up to 40 cats can be stored in the flap, making it ideal for multi-pet households.

When the cat approaches the flap, the sensor reads the chip and only opens the door if the chip's identification number is stored in the system. This enables selective access control so that only authorized cats are allowed in.
How does a microchip controlled cat flap work?
A microchip controlled cat flap works by reading the cat's microchip using RFID technology. The flap's sensor recognises the chip's unique identification number as soon as the cat comes into the reception area. Only when the number is registered in the system will access be granted, ensuring that only authorised cats have access.
