These 25mm diameter stickers are very thin (0.7-1mm thick) with a strong single use adhesive. This enables them to be put on the back of phones (or between a phone and a case), on loyalty tags, inside garage remotes, etc. They are programmed just like the keycards and keyfobs.
NOTE: We STRONGLY recommend programming and testing these before sticking them to the desired surface. Once stuck they will get damaged if you try and remove them. Also, programming can be difficult when they are against a metallic surface such as a phone.
