NFC Dog ID

This particular 3D printed house could be equipped with an NFC (Near Field Communication) sticker on the inside, which provides an added layer of convenience for the owner. NFC technology allows for contactless communication between devices, and in this case, the sticker can be programmed to interact with various smart devices, such as a smartphone. Thus you can make a PDF file with the contact info of your pet or just modify the piece and put the info on the house.
