The best mobile credit card processing readers make it easy for businesses to process credit and debit card payments offline, such as in store, at a trade fair, or on the go.
Taking card payments is increasingly essential for any modern business, but Point of Sale (POS) terminals are usually tied to an internet connection. What happens if you want to sell at a trade fair, or set up a market stall, or any other kind of pop-up shop?
This is where mobile card readers come into their own for credit card processing, allowing you to take card payments wirelessly and on the go. You don't need a checkout till, you just need a smartphone or tablet that can run apps to connect with a mobile card reader.
They can even be great for small mom-and-pop shops that are looking to keep their initial costs down, and a tablet running apps on a stand can work in lieu of a till.
Most merchant services providing a mobile card reader offer rates similar to online payment processing systems. Many charge no monthly fee, just transaction fees in the range of 2.5-3.5%. However, there are options to pay a monthly fee in order to reduce transaction fees down to interchange fees only, i.e. the pennies the bank will charge for movement of funds between accounts.
Where mobile credit card processing really comes into its own is its sheer flexibility. Using nothing more than your own smartphone, a downloaded app, and a cheap card reader costing around $25-$50, you can be ready to start taking payments anywhere there is a cellular network signal. Even then, some merchants offer an offline option.
Even better, it's not just the ability to take payments from credit/debit cards with an EMV aka chip-and-pin, but contactless payments can now also be taken, including Apple Pay, Android Pay, and Samsung Pay.
Here we look at some of the merchant service providers who can provide the best in mobile card readers for taking payments on the go.
Square provides a range of innovative PoS solutions, and their mobile card reader continues this policy. As with Square's products in general, your mobile device can serve as a checkout and sales center for your retail business, and the card reader remains an integral part of that.
The card reader itself is just a small device that clicks onto your smartphone via a Lightning USB connection for iPhones and iPads, or phone jack connection for Android phones. The attachment can then have cards simply swiped through it to be processed.
The swiping process is easy, but it's also secure with no card or customer data being stored in your phone. Instead it's sent over an encrypted connection for processing, and then that's the processing done.
The basic card reader itself is free, and transaction fees are a flat-rate 2.6% + 10c for Visa, Mastercard, Discover, and American Express. Even better is that there are no monthly fees, either.
However, there is a different device required for contactless payments, which allows not just for chip and pin cards to be read, but also use Apple Pay for payments.
Altogether, Square make taking transactions a painless process, and the card reader is both easy to use and simple to work with. The charges are very reasonable, too.

The GoPayment smartphone app is notable, and this has a companion card reader, both of which come for no additional charge.

Another benefit of this service is that there is no setup fee, or any minimum usage level, making QuickBooks more attractive for the lower volume user.

iZettle is a new and improved version of the card reading service that has been around in one form or another for a while now, since 2010 in fact and it's also now owned by PayPal. It’s proved to be very popular and the latest incarnation is likely to boost that appeal. The great thing about it, and perhaps the main reason that it has been a hit with so many people, is that it is one of the simplest solutions out there for taking payments.
The iZettle is a compact card machine that works alongside a very impressive app on your phone to make the processing of payments a doddle. This edition of iZettle is just as attractive as the earlier model and proves to be very affordable, which means that it continues to be hugely popular with small business owners who want a cheapish way to process payments.
Once you’ve bought the card reader you’ll then be charged a fixed rate for each transaction, which makes it a sensible option and monthly fee-free alternative to some of its competitors. The app, incidentally, is free.

PayAnywhere has been in existence for around a decade or so now, although it's only in the last couple of years that it has been improved enough to be called a serious player in the card processing stakes.
PayAnywhere currently comes with two different packages for the mobile market, so currently you can opt for their pay-as-you-go package, which has a 2.69% transaction fee attached to it. That covers transaction processing of under 10k per month for swiped, dip or tap payments.
Meanwhile, keyed entries cost 3.49% plus $0.19 each while there’s also an apparent inactivity fee per month. However, PayAnywhere states on its site that this is applicable only to merchants who do not process a transaction for 12 months. When processing resumes, the inactivity fee will no longer be charged.
