Best Microchip Scanners for 2022

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

In recent years though, pet microchips have played a huge part in reuniting lost loved ones with their owners. It has been mandatory to microchip dogs since 2016, and the government introduced mandatory cat microchipping in 2021 too. Since October 2020 it has also been mandatory for all owners to chip their horses, ponies and donkeys.

But crucially, pets still won’t be found unless somebody scans them. Microchip scanners are commonly used by rescue centres and vets. But if you regularly come by stray cats where you live, it is also a great item to have to hand. It cuts out the need to go to the vet with your rescue, reducing stress for everyone involved.

You may also want to have one to hand to check your pet’s microchip regularly and ensure it hasn’t moved. It is good to also check it still matches up with the records held by the microchip company.

Not all microchips can be read by every scanner. It is best to buy one which is universal and can read any chip. The majority of modern microchips are ISO standard but some non-ISO still exist. You also want something rechargeable, with a good battery life, and which is easy to read.

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!

    The Top Pet Microchip Scanners Reviewed

    Halo Microchip Scanner

    The most innovative scanner on the market, Halo’s revolutionary chip reader is the ideal aid for finding lost animals and comes with software designed to turn you from a concerned animal lover into a successful dog and cat detective.

    In a lightweight steering wheel design that fits perfectly in your grip, it’s perfect for travel and fully rechargeable thanks to a USB port. Yet don’t expect to have to use this much, as with a stand by time of 6 months, it almost never needs recharging!

    Best of all though is that the scanner is compatible with the computer software Scanner Angel, a database designed to keep track of missing animals. This means missing animal data can be stored onto your device at all times so that if your scanner ever takes a reading from an animal registered as lost the Halo will automatically alert you that it needs rescuing.

    This helps remove all hesitation and uncertainty from an encounter with a lost animal, as you’ll always be able to know for certain whether they need help or not.

    It’s the scanner we use personally and can vouch that it never lets us down. The fact it doesn’t need regular charging is ideal for emergencies and it is much more comfortable to hold than many of the others we reviewed.

    • Weight: 100 g

    Sonew Microchip Reader RFID 134.2KHz

    An incredibly underrated mechanism for pet scanners is memory storage, a particularly important feature for those who work with livestock or in shelters, as you need to be able to scan and gain ID information of so many animals, often in quick succession.

    This ID reader from Sonew has the biggest memory of any other scanner on the market, holding onto an amazing 128 tags at once, allowing you to upload batches of unique ID information to a PC rather than just one ID code at a time.

    It’s no surprise then that this is a widely revered gadget in animal management circles where it is also praised for it’s OLED display screen which is readable and clear under strong light.

    An easy to operate handheld model, it’s by far one of the most portable options, with an uncomplicated one-button system and simple to understand backlit display screen.

    But one of our favourite features of Bewinner’s device is its internal historic data reader, which means you can easily navigate previous code readings if you ever need to double-check a past reading.

    Buying Guide

    How we selected the best microchip scanners

    It is easy to think that if a microchip scanner scans a microchip, that is the job done. This is very true, but there are plenty of extras to look out for which will make your life easier.

    For example, as they’re all wireless and portable, you want one with a long battery life that won’t let you down if you forgot to charge it and need it in an emergency. Opt for a rechargeable scanner too – batteries are not reliable. Most come with a USB cable so you can charge it at home or in the car.

    Something with a clear display is beneficial, as well as the option to store certain microchip numbers if you will need them at a later date (say when you get home and need to call the vets to contact the owner).

    We also looked at cost. Microchip scanners aren’t an essential piece of kit for the majority of pet keepers, so you’d likely not use one daily unless you’re a rescuer. Therefore you won’t want to spend a lot. But we found that some of the cheapest microchip scanners simply don’t live up to the task at hand, so we had to find a balance.

    Because they aren’t a hugely popular item, there aren’t many brand names out there. Halo is probably the best-known brand if you’re concerned about the safety and security of non-branded electrical items.

    It is also best to buy a scanner that can read microchips at all frequencies, too. Microchips typically come in two types, ISO and non-ISO – you can read more about this in our FAQs.

    Size is also important. 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.

    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! This is something we looked for, too. It also makes your job easier, especially with stray or feral animals which may not allow you to get close.

    Other Buyers Ask...

    How much is a microchip scanner?

    They can range from around £20 to nearer £100. Cheaper models may just scan a microchip and give you the number, whereas a top of the range model could be connected to a database of lost animals online.

    However, it’s rare that you would ever have to pay more than £60 for a decent top of the range model and the ones at the bottom of the range still do the most essential job of giving you the microchip number.

    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, microchips 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 the 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. Take the time to be extra sure.

    Why do I need a universal microchip scanner?

    A universal microchip scanner will read both ISO and non-ISO microchips.

    ISO (International Standards Organisation) microchips usually broadcast information on a frequency of 134.2kHz, whilst non-ISO frequency is 125 kHz or 128 kHz. The majority of scanners are now universal, so will operate at all frequencies, but some cheaper modern models will only scan at ISO level.

    ISO (International Standards Organisation) microchips are recognised worldwide. Non-ISO microchips are mostly found in older dogs and cats which were chipped before ISO was established, so while they’re rarer there is still a risk you could encounter one.

    Travel companies in the EU can read microchips that meet ISO standards 11784 and 11785. If you’re travelling to the EU with your pet and they don’t have an ISO microchip, you may have to take your own universal reader when you travel. Some companies and countries won’t allow non-ISO microchips, however, so it is essential to check before you travel.
