Its versatility makes it suitable for counter use or mobile checkout across a store, event, or pop-up environment.
Square Handheld — Portable Credit Card Processor
Square Handheld is designed for mobility, allowing payments, tableside ordering, and barcode scanning in a compact form. It features a dust and splash resistant build with a long-lasting battery and offline payment capability to minimize downtime. The slim, pocketable design supports quick transactions in environments like retail floors, restaurants, or service-based settings where customers expect fast service.
SumUp Plus Card Reader — Bluetooth and NFC
SumUp Plus is a compact, mobile card reader that pairs with smartphones via Bluetooth. It accepts magstripe, chip, and contactless payments including Apple Pay and Google Pay. This flexibility supports fast checkout in fields like street fairs, markets, or service calls where a full POS is impractical. It’s ideal for solo operators or small teams seeking a simple, low-friction payment experience.
Verifone VX520 Dual Comm — Durable Terminal
The Verifone VX520 Dual Comm combines a compact footprint with reliable EMV and dual communication options, making it a robust choice for businesses in need of steady performance in challenging environments. It includes an integrated smart card reader and supports PCI compliance. While it emphasizes a traditional hardware approach, its durability and dependable processing remain appealing for brick-and-mortar operations and field services alike.
Deftun MSR90 USB Swipe Reader
The Deftun MSR90 offers USB plug-and-play setup, reading up to three tracks of data across common formats. It’s a straightforward accessory for quick processing wherever a computer or tablet is used as the point-of-sale interface. This reader is suitable for kiosk stations or small businesses that require a simple card swipe option without a full standalone terminal.
Buying Guide
Key considerations when choosing a mobile credit/debit card machine include compatibility, ease of use, and where you plan to sell. If you operate a retail storefront with occasional pop-ups, an all-in-one device like Square Terminal can streamline operations by combining payment, receipt printing, and sales tracking. For fully mobile teams, a slim handheld with a strong battery, like Square Handheld, helps you take payments anywhere with minimal setup.
Payment types supported are critical. Look for readers that handle magstripe, chip (EMV), and contactless payments (NFC), including Apple Pay and Google Pay. In busy environments, speed matters, so note processing times and whether chips complete within a couple of seconds. Durability and resistance to dust or splashes are important in hospitality or field service contexts, where devices face daily wear.
Security and compliance should guide your choice. Ensure devices and readers support PCI standards and that any embedded card data is encrypted. If you need a rugged option, consider models with reinforced housings or protective accessories. Finally, factor in cost structure—monthly fees, transaction rates, and lock-in terms—to determine long-term value for your business model.
For teams that require a simple setup with minimal hardware, USB swipe readers paired with a tablet or laptop may suffice. In contrast, high-volume environments or multi-location operations may benefit from purpose-built terminals that offer offline capabilities, quick receipt printing, and integrated inventory or sales analytics.
These five options provide a spectrum from compact readers to robust all-in-one terminals, helping American businesses select mobile payment solutions that fit their specific workflows and customer expectations.
