Each iButton leaves the factory with a unique code, which the reader recognises as soon as you touch it — just like swiping a card, but more robust and much simpler.

​

Why is it more secure? Because it can’t be copied.
The code is fixed at the factory; there are no unauthorised “copies”.

​

You can delete it from the system whenever you like.

​

It works even without the internet: the reader simply checks the key and, if it has been added, it opens the door — all security is local, under your control.

​

Built for everyday use: metal body, designed to withstand frequent use, rain and dust.

No batteries in the key: nothing to charge, nothing to replace — touch, beep, open.

What is an iButton? 

It’s an electronic key in the shape of a small metal coin.
