Mobile credit card processors have transformed how small businesses, pop-up shops, and restaurant staff accept payments. No longer tied to a fixed checkout till, merchants can now process credit and debit card transactions anywhere there's a cellular signal ā using nothing more than a smartphone, a downloadable app, and a compact card reader costing between $25 and $50.
These systems support EMV chip-and-pin cards as well as contactless payments like Apple Pay, Google Pay, and Samsung Pay. Most providers charge no monthly fee, only transaction fees ranging from 2.5% to 3.5%. Some offer a monthly subscription to lower rates to interchange fees alone ā the small charges banks levy for moving funds between accounts.
Beyond payment processing, the best mobile point-of-sale (POS) systems help manage inventory, ensure compliance with payment regulations, reduce chargeback fraud, and protect against data breaches. Below we highlight the top mobile credit card processors of 2026.
Best Affordable Mobile Credit Card Processor: SumUp
SumUp is a mobile card reader available in 31 countries, though it's a relative newcomer to the US market. It supports EMV chip cards and is powered via a micro-USB port with a lithium-ion battery. The reader connects via Bluetooth to your smartphone using a free app.
This solution suits lower-volume users thanks to a fixed transaction cost with no monthly fee or minimum usage. It accepts MasterCard, Visa, American Express, and Discover, plus Apple Pay and Google Pay. Payouts reach your bank account in one to two business days. However, you must use the physical card reader for every transaction ā manual entry is not supported.
SumUp offers a straightforward, low-cost way to accept card payments on the go, with no hidden fees and broad card acceptance.
