Best Microchip Scanners for 2020

Thousands of pets go missing in the UK every year, causing many owners to fret, worry and suffer more heartbreak than you could possibly imagine.

In recent years though, the ever-faithful pet microchip has played a huge part in reuniting lost loved ones with their doting owners and in the UK 75% of all lost dogs and 45% of lost cats are returned to their homes thanks to chips.

But crucially, pets still won’t be found unless somebody finds them… and then physically scans them or takes the time to take them somewhere they can be.

Not many people are so kind, but with a good-quality microchip ID scanner, you can become a good pet samaritan with relative ease, helping your community and lost pets find their way home.

So to help you find a perfectly portable scanner with advanced technology and insights, we’ve scoured the market to find the very best pet ID finders on the market!

    Buying Guide

    Things To Consider


    When shopping for scanners, there is almost nothing made of the radio frequency your reader can pick up, despite it being one of the most important things when it comes to accurate or even just successful readings.

    Most microchips operate at 125KHz, 128KHz and 132.2KHz and so you need a scanner that can operate at all of these frequencies to be in with any chance of successfully identifying an unknown chip.


    Nobody wants to go round the park carrying a big huge metal detector and there are plenty of dinky scanners which animal lovers can carry around in their bags covertly and simply bring them out when they suspect an animal is a stray.

    Chip Universality

    One of the most confusing aspects of microchip scanners is their chip reading universality, as there are many different types of pet microchip out there and so some scanners can only pick up and read certain ones.

    That’s why getting a scanner that’s as universal as possible is incredibly important, especially if you own a shelter. There are plenty of horror stories out there of found pets being brought to shelters and those establishments lacking scanners which pick up rare frequencies or certain digits of chips.

    In general, it’s most important to have a scanner which can pick up ISO (International Standards Organisation) standard chips, as unsurprisingly, these are the most commonly used.

    This is a global standard intended to give continuity amongst identification systems worldwide, so that if pets get lost in other countries, most scanners will still be able to pick up a reading.

    The most common ISO standard chips are FDX-B and HDX chips which are detectable at 134.2KHz.

    Non-ISO chips also exist though, especially in older animals chipped before standards were implemented. These will usually emit lower frequencies of 125KHz or 128KHz and are commonly FDX-A.


    Nobody likes using batteries these days and there’d be nothing worse than coming across a stray animal only to discover your triple A’s had gone dud. Most scanners with USB cables and ports are thankfully rechargeable, meaning it’s never something you’ll have to worry about.

    Tag Saving

    If taking in a lost animal isn’t really an option for you, or you are in a career where you’re having to scan lots of pets per day, it’s handy to get a device which can store hundreds of identity tags at once onto its system so you can upload your data at a more convenient time.

    Computer Compatibility

    Scanners which are compatible with database software and such are vital to helping reunite owners with their lost pets, as you can plug in your scanner and check which ID tags you have found are listed as missing on such databases.

    Reading Distance

    The further the reading distance (the distance at which a scanner can detect the chip’s unique ID code), the stronger the detection capabilities of the device. In general, an incredibly strong scanner can pick up readings at 15cm or further!

    Other Buyers Ask...

    How much is a microchip scanner?

    Given that you’re not only paying for a scanner but also an item which is then compatible with online software for tacking and tracing I.Ds, microchip readers are a piece of technology that’s understandably expensive.

    However, it’s rare that you would ever have to pay more than £60 for a truly top of the range model and there are plenty priced as low as £40 which can still do the job.

    How do you use a microchip scanner?

    The most important thing to remember when using a pet microchip reader is patience. Although most pets are scanned in exactly the same place, chips can shift and move around the body over time. Plus your scanner is having to take a reading through actual flesh, so it might not pick it up first time round!

    When scanning, begin between the pet’s shoulders and move east to west, slowly moving down. Then repeat the process north to south from the pet’s head to their tail. Some people opt to do this in ‘S’ shaped patterns across the pet’s back.

    If this isn’t fruitful, try the flanks and sides of the animal, including legs, neck, chest and belly, just in case the chip has moved substantially within the body.

    Then as a final scan, change the position of the scanner in your hand by 90 degrees, as sometimes this can have an effect on readings.

    This whole process can take a minute or more, so it’s important to be patient, as it really is all too easy to just assume an animal is unchipped. Why not take the time to be extra sure
