with Plus FINGER

All smart locks embodies authentication parts in the main product, meaning the location is fixed with the product itself. Is that the best way? What about children with short heights or handicapped on wheelchair? Keyin’s Plus FINGER can be installed anywhere you want. On the door, on the wall, inside the door, or you can even carry it if you wish! You can just stick it, or screw it for better stability. All the choices are up to you.
* It’s recommended the devices are installed within a Bluetooth connecting distance with a smart lock

Sometimes it is necessary to keep people inside. In a police station or a nursing institution for example.

Most locks just have an open/close button on the inner body, so that anyone from inside can escape without authentication.

Special locks of Keyin are specialized for these occasions. The open button in the inside is removed and is opened only when credentials are met. Which credentials? That is where PLUS LINK comes in. Just use Plus FINGER.
