QR tag, microchip or GPS for dogs and cats?
These tools serve different purposes. QR tags help a finder contact you. A microchip identifies your pet through a specialist reader. A dedicated GPS tracker shows location while powered and within coverage.

How does a QR tag work?
The QR opens a browser page with your pet’s photo and contacts. GeoPetPro creates the profile when you order, so the tag arrives ready to use. A finder can contact you and choose to share their phone’s position.
What if nobody scans the QR?
The tag does not transmit location on its own. Someone must scan it to reach your contacts. QR identification can therefore complement a GPS tracker.
What is needed to open a profile?
A phone that reads QR codes and an internet connection. The tag has no battery, SIM card or NFC. No GeoPetPro app is needed.
How do I keep the profile useful?
Use a recent photo, a phone you answer and, if possible, an alternative contact. Receive an email code to change those details. Only publish useful instructions for the finder.
Which style should I choose?
Choose standard for the brand logo, or personalised for your pet’s name engraved on the front. Digital features are identical. Shipping in Portugal is included, with expected delivery in 3–7 business days.
