No matter how careful you are as a pet owner, sometimes dogs or cats go missing and it can be difficult to track them down. Besides traditional collar tags and microchips, pets can now wear “smart” ID tags too.

According to an article on the website Live Science, smart tags can be a good way to help track your pets. Many of these tags have a QR code that can be scanned with a smartphone. When scanned, a QR code can supply someone who finds your lost pet with much more data than a traditional tag.

They can see the animal’s photograph and medical information, as well as your contact details. This will enable them to contact you right away to let you know your pet has been found.

Contact information can be changed quickly and easily, so you can add your pet sitter’s or doggy daycare’s number if you are not available.

Many companies make personalized ID tags with QR codes. If you’re ready to upgrade to a smart tag, check out this article from PetHub to learn more about smart tags before you buy.
