Your pet may be microchipped, but without a scanner, that chip cannot help. Microchips do not track or alert—they simply store an ID number that must be read by a compatible device.
Today, scanners are no longer just for vets. Compact models like the one from Tera make it easy for pet owners to scan at home or on the go.
In this guide, you will learn what a pet chip scanner does, who needs one, how to choose the right device, how to use it, what to do after scanning, and answers to common questions.
Let’s get started.
What's a Pet Chip Scanner and How Does It Operate?
A pet chip scanner is a handheld tool that reads the ID number stored inside a microchip implanted under your pet’s skin. It works by using radio frequency identification, or RFID, to detect and display that number on a screen.
When you pass the scanner over the pet’s neck or shoulder area, it sends out a low-power signal. If there’s a microchip nearby, the chip responds with its unique ID. This number can then be matched to contact details stored in an online database.
Most pet microchips use something called FDX-B technology. These chips operate at 134.2 kHz, which is the international standard. Some older or regional chips use different frequencies like 125 kHz. That’s why not all scanners work with all chips—and why it matters to choose one that’s compatible.
A scanner doesn’t track or store location. It simply reads and displays the number stored in the chip. Consider it as a key to reveal your pet's identity.
Now that you know how it works, let’s look at when and why having your own scanner might make sense.
Who Needs a Pet Chip Scanner?
A pet chip scanner isn’t just for professionals. If you belong to one of the following groups, owning one could truly make a difference.

If you see yourself in any of these roles, a scanner can turn uncertainty into confidence. And in a moment when minutes matter, having one nearby could change everything.
How to Select the Suitable Pet Chip Scanner
Not all pet chip scanners are identical—you don't require the most advanced one. You just need one that fits how and where you’ll use it.
Start with chip compatibility. Most microchips today use 134.2 kHz, also known as ISO 11784/11785. Make sure your scanner supports this frequency. Some older chips use 125 kHz, so if you're scanning pets with unknown origins or older chips, dual-frequency support is helpful.
Next, think about the screen. Basic scanners just show the chip number. Others have larger displays or memory to save multiple scans. If you work with more than one animal, this can save time.
Do you need portability? Many scanners are handheld and lightweight, perfect for use at home or outdoors. If you’re scanning in bulk or at a shelter, battery life and scanning range may matter more.
Also consider power and connectivity. USB-charging is standard. Some models connect via Bluetooth or even sync data to apps or PCs. If you prefer simple plug-and-scan, avoid complex setups.

How to Use a Pet Chip Scanner
Scanning a pet’s microchip might sound technical, but it’s actually simple. Here's a step-by-step guide on how to do it—no veterinary degree needed.
-
Turn on the scanner and check the screen.
Most scanners activate with a button or when plugged in. A quick screen light-up means you're ready to go.
-
Hold the scanner steady in your hand.
Make sure the sensor side is facing your pet. Take a deep breath—your calm helps keep your pet relaxed too.
-
Gently scan from the neck down to shoulder blades and along the spine.
This is where most microchips are placed. Move slowly and steadily, like waving a wand.
-
If nothing shows, expand the scanning area to the entire body, moving slowly and methodically.
Microchips can shift slightly over time. Go over the area twice if needed—don’t rush.
-
Once a number appears, you’ve found the chip.
That’s your pet’s unique ID. It might look like a long string of digits—don’t worry, it means the chip is working.
-
Jot it down or snap a photo of the screen.
You’ll need this number to check or update your pet’s registration later.
Even if it takes a few tries, scanning is safe and painless for your pet—and empowering for you.
Now that you’ve found the chip number, let’s walk through what to do with it.
What to Do After You Scan the Chip
When a number appears on your scanner, you’ve found your pet’s microchip. This is their unique ID—like a digital name tag under the skin.
Next, visit a tool like the AAHA Universal Pet Microchip Lookup Tool petmicrochiplookup.org. Input the number to search participating registries and identify which database(s) have registration information for that chip number. You won’t see personal details, but you'll learn which registry to contact for information linked to that microchip ID.
If the lookup tool indicates the chip is registered, contact the identified registry to ensure your contact information is up to date. If no registration is found, you will need to register the chip with a reputable pet recovery service. Updating information with a registered database is usually free, but initial registration may involve a fee depending on the service.
Maintaining up-to-date microchip information for your pet ensures that a single scan can reunite you if they ever go missing. Don’t wait until something happens—take two minutes to make sure everything is in place.

Frequently Asked Questions
Can I scan my pet’s microchip with my phone?
No, smartphones cannot read pet microchips. You need a dedicated RFID scanner made for that purpose.
Will a vet scan my pet’s chip for free?
Many clinics will do this at no charge, especially if your pet is lost. It’s best to call and ask.
How do I know if my pet has a chip?
Ask your vet to check, or use a scanner to try reading one. In North America, chips are typically implanted just in front of the shoulder blades. In continental Europe the standard site is the mid‑left side of the neck, so scan both areas if you’re unsure where the chip was placed.
What if nothing shows up when I scan?
Try scanning again more slowly or at a different angle. If still no result, your pet may not have a chip or it may be unreadable.
Can one scanner read all pet chips?
Not always. Most modern chips use 134.2 kHz (FDX-B). Some scanners only support this, while others also read 125 kHz. Check before you buy.
What happens after I get the chip number?
Go to a registry lookup site and enter the number. You’ll see if it’s active and where it’s registered.
Is scanning safe for my pet?
Yes. It’s non-invasive and painless. The scanner simply reads a signal from the chip—nothing is injected or removed.
Can I buy a chip scanner for home use?
Yes, and it’s a good idea. Devices like the one from Tera are simple, affordable, and work well for home or travel.
