Some celebrities love animals so much that they carry a microchip scanner if they encounter stray pets. Whenever a stray dog or cat crosses their path, they can easily scan the lost souls for a microchip. 

Millie Bobby Brown is a celebrity who is passionate about animals. Most widely known for her role in the hit television series Stranger Things, Brown founded a rescue organization called Joey’s Friends. In an interview with Vogue, Brown talked about the microchip scanner she carries around in a Louis Vuitton bag. 

You don’t have to be a celebrity to make a difference in the lives of pets, and Brown hopes her scanner idea will inspire other pet parents. Before we give you the full scoop on her dog rescue and charitable efforts, here’s how you, too, can help save lost or stray pets with a microchip scanner.

What to Look for in a Microchip Scanner for Pets

When purchasing a microchip scanner for personal use, here’s what to look for:

Microchip Compatibility: Look for a microchip scanner that supports ISO11784/11785 FDX-B, most commonly used in the United States. EMID is often used for older microchips, whereas rescue groups, shelters, and veterinarians use ID64 or AVID encrypted chips.

Read Range: A more extended range means easier scanning, which is ideal for pets who will wiggle and move around when you try to scan. Read range refers to the distance between the scanner and the chip it can read (around one to nearly 5 inches away).

Speed & Accuracy: You’ll want the scanner to display the chip quickly, as in a second or so. A higher-quality scanner can help reduce reader errors and missed microchips.

Display & Data Storage: OLED Screens or TFT screens are easier to read in low-light conditions or outdoors. Some models store your scan history or allow you to export the identification numbers via Bluetooth/USB.

Battery Type: Look for a rechargeable battery such as lithium-ion, which is more convenient than standard battery-operated models (i.e., AAA or AA batteries).
Portability & Durability: A lightweight and compact design is ideal for travel or on-the-go usage. If you plan to keep it with you when outdoors, look for a waterproof or more rugged casing.

Microchips come in different frequencies; not all scanners can read every type. The current standard is the 15-digit microchip, which most modern scanners can detect. 

However, older microchips, like the 10-digit ones used in the early 2000s by companies like HomeAgani, use a different frequency and may require a compatible scanner. AVID also produces a unique 9-digit microchip, adding another complexity layer. 

Bottom line: Never give up if your microchip scanner isn’t working or can’t find a microchip. Microchips are known to migrate and may not always be easily found. Double-check with your local shelter or veterinarian for further assistance reuniting lost pets. 

How to Prevent Your Pets From Going Missing

Keeping your pet microchipped and ensuring the data is accurate are two keys to reuniting with them if they get lost. Be sure to update your microchip company should you change addresses, names, pet ownership, phone numbers, etc.
