If you for some reason don't want to want to use the Den4Dogs App you can also buy keycards and use those instead. These have a value of NOK 115,- or NOK 250,- and can be bought here in our webshop. To use them simply hold it in front of the den's display at about 1cm distance. The door will open and you have 20 sconds to open the door and let your dog get in. To collect your dog you simply hold the same card in front of the display again. Only your card can open the door when your dog is in the den.
