Mobile Payment Systems: We Put Them to the Test

Why Trust Techopedia

If you're in business and are looking for a mobile payment processing system, there are now countless options to choose from. We test 8 and provide full results.

As an amateur artist kicking around the idea of selling my work, I’ve recently wanted to know about the best way to accept payments to a mobile phone. If you're in business and are looking for a mobile payment processing system, there are now countless options to choose from. Card readers – tiny dongles that usually plug into your mobile device’s stereo jack – allow you to accept all major credit cards on almost all new devices, from phones to tablets. (For background reading, check out Cache, Text or Direct Bill: The Truth About Mobile Payment Systems.)

That's a big improvement over only a few years ago, when if you wanted your business to be able to receive more than just cash, you needed expensive hardware and a costly card processing service. No more. Today, anyone with even a smartphone or a tablet can process almost any payment, anywhere.

Belinda Mays, a success strategist who uses Square mobile payments told me,

"I was conversing with someone about what I do and I mentioned my book and we discussed it briefly … They asked where they could get a copy and I said, 'right here'. They said, 'I don't have any cash on me.' 'Not to worry,' I told them, 'I can process your payment on my phone.' I popped open the trunk, swiped their card, gave them the book, the receipt was sent to their email, and voila, a sale."

Point of sale systems are convenient for both vendors and customers, and allow mobile transactions to be done in a whole new way.

"I love that I can walk my 'cash register' over to my customer, which I see as another way to provide service," said Jonathan Plotzker co-owner of a skincare company called Heliotrope San Francisco.


And of course, processing the payment on a phone – rather than reverting to old-school methods like manual carbon-copy devices – adds a level of security for the consumer, especially since those credit cards never have to leave their owners' site. So, although mobile payment systems are not used in overwhelming numbers yet, the number of businesses using these devices is growing.

Only a small number (10 percent) of businesses that responded to ControlScan’s 2012 Mobile Payment Acceptance Study said they were currently using a mobile device to process card-present (CP) payments; however, those who were using the technology indicated they were satisfied with current mobile hand-held technology and the mobile payment systems that support them. Personal services organizations had the highest adoption rate (17 percent), with 47 percent of these respondents replacing their traditional POS with one or more mobile devices.

Mobile Payment Systems: High Tech or Tech Wreck?

Recently, I tested eight devices and their respective mobile apps. The majority of the devices in this shootout are powered by the stereo jack, which typically requires that the volume be turned to the maximum. All the card readers tested work with most credit cards and on most devices, especially Apple iOS and Android. They all offer some kind of encryption, and none of them stores any credit card information on the either the phone or tablet. Scanning the cards can be fickle sometimes -these readers are in their infancy after all – but most of the readers will do it within three tries. In many cases, a beat-up magnetic credit card strip appears to be to blame, rather than the hardware or phone. Here’s our shoot out.
