Three generations of dog identification technology exist side by side: metal tags with stamped text, QR codes linking to digital profiles, and GPS-enabled smart tags that track your dog in real time. Each solves the same problem - getting a lost dog home - through completely different means, at completely different price points, with completely different tradeoffs.
Here’s a direct comparison to help you figure out which combination makes sense for your dog.
The Three Technologies
Engraved Tags
How it works: Text is physically stamped, laser-etched, or diamond-engraved into a metal or plastic tag. Anyone who picks up your dog reads the information directly.
Requirements: Nothing. No phone, no app, no internet, no battery. Just eyes.
Cost: $5-$25 one-time. No subscription.
Lifespan: 2-5+ years depending on material and engraving method.
QR Code Tags
How it works: A QR code on the tag links to an online profile. A finder scans the code with any smartphone camera and sees your contact information, dog’s medical details, photos, and sometimes the GPS location of the scan.
Requirements: The finder needs a smartphone with a camera (which is nearly everyone these days).
Cost: $10-$30 for the tag. Free basic profiles; $3-$10/month for advanced features on some platforms.
Lifespan: The tag lasts 2-3 years. The digital profile lasts as long as the service exists.
Smart/GPS Tags
How it works: A collar-mounted device uses GPS satellites and cellular networks to transmit your dog’s real-time location to your phone app.
Requirements: Cellular service (from the tag’s built-in SIM), regular battery charging, and your phone.
Cost: $30-$500+ for the device. $5-$15/month subscription for cellular service.
Lifespan: 2-3 years before battery degradation or technology obsolescence.
Direct Comparison
| Feature | Engraved | QR Code | Smart/GPS |
|---|---|---|---|
| Works without tech | Yes | No (needs phone) | No (needs app + cellular) |
| Information updatable | No (need new tag) | Yes (edit profile online) | Yes (via app) |
| Location tracking | No | Scan location only | Real-time GPS |
| Monthly cost | $0 | $0-$10 | $5-$15 |
| Battery needed | No | No | Yes (charge daily-quarterly) |
| Works in rural areas | Yes | If finder has phone | If cellular coverage exists |
| Works underwater | Yes | No (QR won’t scan wet) | Most are waterproof |
| Finder can use immediately | Yes | Within 30 seconds | N/A (you track, not finder) |
When Each Type Wins
Engraved Tags Win When…
- Speed matters. Anyone - including children, elderly neighbors, and people uncomfortable with technology - can read a tag instantly. No scanning, no apps, no loading screens.
- You’re in an area with limited technology access. Rural communities, developing countries, outdoor wilderness areas.
- You want zero maintenance. No batteries to charge, no profiles to update, no subscriptions to remember.
- Budget is the priority. A $6 GoTags tag does everything an engraved tag needs to do.
QR Code Tags Win When…
- Your information changes frequently. Moved recently? Changed phone numbers? Traveling with your dog? Update the digital profile from your phone in 30 seconds. An engraved tag requires buying a new one.
- You want to include more information than fits on a tag. Medical conditions, behavioral warnings (“shy, please don’t chase”), multiple contact numbers, your vet’s number, a photo of your dog.
- You want scan notifications. When someone scans the QR code, you receive an alert, often with the scan location. This tells you your dog was found even before the finder calls you.
Smart/GPS Tags Win When…
- Your dog has escaped before. You don’t need someone to find your dog - you know where they are immediately.
- You let your dog off-leash. Hiking, hunting, or in unfenced areas where your dog could wander.
- You want proactive tracking, not reactive identification. GPS tracking tells you where your dog is right now, not where someone found them later.
- You need health monitoring. Most GPS trackers also monitor activity, sleep, and sometimes heart rate.
The Layered Approach (What Vets Recommend)
Veterinarians and animal control officers consistently recommend layering multiple identification methods:
| Layer | Method | Why |
|---|---|---|
| 1 | Microchip | Permanent, can’t be lost or removed, read by any shelter or vet |
| 2 | Engraved tag | Immediately readable by anyone, no technology required |
| 3 | QR or GPS tag | Extended information or active tracking (optional but valuable) |
Layer 1 + Layer 2 should be considered mandatory. A microchip covers the scenario where the collar comes off (it’s implanted under the skin). An engraved tag covers the scenario where someone finds your dog but doesn’t have access to a microchip scanner (which most people don’t).
Layer 3 is optional but valuable for dogs that are escape risks, off-leash frequently, or in higher-risk situations.
Cost Over 3 Years
| Method | Year 1 | Year 2 | Year 3 | Total |
|---|---|---|---|---|
| Engraved tag | $8 | $0 | $8 (replacement) | $16 |
| QR tag (free plan) | $20 | $0 | $20 (replacement) | $40 |
| QR tag (premium plan) | $20 + $72 | $72 | $72 | $236 |
| Apple AirTag | $49 | $4 (battery) | $4 (battery) | $57 |
| Fi GPS collar | $20 + $168 | $168 | $168 | $524 |
| Tractive GPS | $60 + $108 | $108 | $108 | $384 |
An engraved tag is roughly 20x cheaper over three years than a GPS tracker. But if your dog escapes and a GPS tracker brings them home in 20 minutes versus 2 days of searching, the economics change entirely.
What Happens When Each One Fails
Understanding failure modes helps you choose the right backup:
| Method | Failure Mode | Consequence |
|---|---|---|
| Engraved | Tag falls off or text wears smooth | Finder can’t contact you |
| QR code | Service shuts down or QR damaged | Code links to nothing |
| GPS | Battery dies or no cell coverage | No tracking available |
| Microchip | None (permanent, no battery) | Requires scanner to read |
This is exactly why layering works. Each method’s failure mode is covered by another method’s strength.

Frequently Asked Questions
Can a QR code tag replace an engraved tag?
Not as a sole identification method. If the QR code gets scratched, the service goes offline, or the finder doesn’t know how to scan a QR code, you’re left with no identification. Use a QR tag in addition to an engraved tag, not instead of one.
Is an AirTag a good substitute for a GPS tracker?
For urban and suburban dogs, an AirTag provides surprisingly good tracking at a fraction of the cost and with no subscription. But it’s not real-time GPS - it only updates when an iPhone passes nearby. For serious escape risks or rural areas, a dedicated GPS tracker (Fi, Tractive) is necessary.
My dog never leaves the yard. Do they still need ID?
Yes. Gates get left open, delivery drivers enter yards, fences develop gaps, and natural disasters can separate dogs from their homes. An engraved tag and a microchip cost under $70 total and last for years. The cost of not having them, if your dog does get out, is incalculable.
