A Common Misconception
Many pet owners believe that microchipping their pet means they can always find them if they go missing. It's an understandable assumption — but it's not how microchips work. Understanding the real difference between a microchip and a GPS tracker is essential for building a complete safety net for your pet.
How Microchips Work
A microchip is a passive radio-frequency identification (RFID) device — about the size of a grain of rice — implanted under your pet's skin, usually between the shoulder blades. It contains a unique identification number linked to your contact details in a national registry.
What Microchips Can Do
- Permanently identify your pet if found by a vet, shelter, or rescue organization
- Prove ownership in disputes
- Cannot be removed or lost like a collar
- Require no battery, no subscription, and no maintenance
What Microchips Cannot Do
- They cannot track your pet's location. A microchip only works when a scanner is held directly over it — typically within a few centimetres.
- They don't send alerts if your pet escapes.
- They don't help you find your pet proactively — only reactively, if someone finds your pet and brings them to a scanner.
How GPS Trackers Work
A GPS tracker is an active device that uses satellite positioning combined with cellular or radio networks to report your pet's real-time location to your smartphone. It requires battery power and, for cellular models, a monthly data subscription.
What GPS Trackers Can Do
- Show your pet's precise location in real time on a map
- Alert you the moment your pet leaves a defined safe zone (geofencing)
- Log movement history and activity levels
- Actively help you locate and retrieve a missing pet
What GPS Trackers Cannot Do
- They can be lost if the collar or harness comes off
- They require charging and may run out of battery at critical moments
- They involve an ongoing subscription cost for cellular models
- They do not serve as legal proof of ownership in the way a microchip does
Head-to-Head Comparison
| Feature | Microchip | GPS Tracker |
|---|---|---|
| Real-time location | No | Yes |
| Escape alerts | No | Yes |
| Proof of ownership | Yes | No |
| Battery required | No | Yes |
| Monthly cost | No | Often yes |
| Can be lost | No | Yes (if collar removed) |
| Works without scanning | No | Yes |
| One-time setup | Yes | No (ongoing maintenance) |
Why You Need Both
Microchips and GPS trackers solve different problems. Together, they create a comprehensive safety system:
- The GPS tracker is your proactive tool — it tells you where your pet is right now and alerts you before they get too far.
- The microchip is your fallback identification — if the collar is lost or the tracker battery dies, your pet can still be identified and returned to you.
Think of it this way: the GPS tracker helps you find your pet; the microchip helps your pet find their way back to you through the kindness of strangers and professionals.
Keeping Your Microchip Registration Up to Date
A microchip is only useful if the registry details are current. Many reunions fail not because the pet wasn't chipped, but because the owner's address or phone number had changed and the registry was never updated. After any move or change of contact details, updating your microchip registry should be on your to-do list.
Combining a registered microchip with a reliable GPS tracker — and keeping both maintained — gives your pet the strongest possible safety net. Don't choose between them; use both.
