Most phones aren’t built to read pet microchips. Smartphones use NFC at 13.56 MHz, while common pet chips are low‑frequency (typically 134.2 kHz FDX‑B and some older 125 kHz tags), so they usually aren’t compatible.

• Use a dedicated scanner: Handheld RFID readers are designed for pet microchips and are available online.
• Visit a pro: Many veterinary clinics, shelters, or animal services can scan and confirm an ID number.
• After you get the ID: Check with the microchip registry to confirm the chip is registered and your contact info is current.

Results can vary based on chip type and placement. If you’re unsure which route to take, contacting a local clinic for guidance can help.

You can scan at home with a compatible handheld reader. A slow, patient approach can improve results.

1. Charge and power on: Select the correct mode (FDX‑B 134.2 kHz; use 125 kHz if your device supports it and you suspect an older chip).
2. Reduce interference: Remove metal tags and move away from electronics when possible.
3. Scan technique: Start between the shoulder blades and move slowly in an S‑pattern around the neck, shoulders, and chest. Hold the reader close and keep your pet calm.
4. Repeat passes: Make multiple sweeps and rotate the reader’s angle.
5. Record the number: Carefully note the full ID as displayed.

If you can’t get a read, try a dual‑frequency reader or ask a vet or shelter to confirm. Outcomes may vary by chip orientation and placement.

You can shop for handheld pet microchip scanners online at Walmart, with options for shipping or store pickup. When comparing devices, consider:

• Compatibility: Support for ISO 11784/11785 FDX‑B (134.2 kHz); dual‑frequency models can also read some 125 kHz tags.
• Power and charging: Rechargeable battery, USB charging, and useful battery indicators.
• Display and alerts: Clear screen readability and audible/vibration alerts for successful reads.
• Data features: Basic ID display vs. on‑device storage or PC/mobile transfer.
• Durability and comfort: Portable size, comfortable grip, and protective housing for field use.

Product pages typically list supported standards and features, which can help you choose a scanner suited to your pets and environment.

There are a few ways to get a chip scanned:

• Veterinary clinics: Many will scan as a courtesy, but policies can vary by location. It’s a good idea to call ahead.
• Animal shelters or rescue groups: Often have scanners on hand and may help check an ID number.
• Community events or animal services: Mobile clinics and local agencies sometimes offer scanning.
• At home: You can use your own handheld scanner if you prefer.

Any fees are set by the individual organization. After obtaining the ID, following up with the microchip registry can help confirm registration details. Availability and costs may differ by area.

Start with compatibility, then choose features that fit how you’ll use it.

• Standards and frequency: Look for ISO 11784/11785 FDX‑B (134.2 kHz), which is widely used for dogs and cats. If you might encounter older tags, consider a reader that also supports 125 kHz.
• Read performance: Check the listed read distance and plan to scan slowly for best results.
• Power and portability: Rechargeable battery, USB charging, compact size, and comfortable grip.
• Feedback and storage: Clear display, buzzer/vibration, and optional on‑device record keeping or data export.
• Durability: Protective housing or water‑resistant design for barns, clinics, or outdoor use.
