Our collar ID tags that glow in the dark come with a one-of-a-kind QR code that can identify pets using any smartphone. Pet parents simply register the tag (for free) and add pet and owner information.  
 
How it Works
The animal’s identification QR code is recorded on the tag's body. When read with a phone, the pet’s and owner’s details are displayed on the screen, and the owner receives a GPS location of the person who found the pet!
 
The tag is made of ABS plastic and has a luminous border that glows in the dark for up to 12 hours, making it easier to identify the animal at night.
