This safety QR sticker for door safety will help you to identify the person who knocks on the door. For example, if anyone comes to your door besides knocking on the door, they will scan the QR sticker which has already been pasted on the wall near your door. After scanning, the QR sticker video chat/ audio call is automatically connected to the house owner, and one more special thing about this sticker is there is no need for wires, installation, or electricity and you can use this sticker at the house as well as the office.
