Square Terminal — All-in-One Payment Device

Square Terminal integrates payment acceptance, sales ringing, and receipt printing in a single device. It supports major credit and debit cards and offers a single, predictable processing rate with no long-term contracts. Card chips process in roughly two seconds, enabling quick checkout at the counter or anywhere in the store. Best for: small shops and hosted events where a compact, all-in-one solution reduces clutter and speeds up transactions. Limitation: higher upfront hardware cost may be a consideration for very small teams.
Square Reader for magstripe (USB-C)

This magstripe USB-C reader is designed for quick adoption by businesses already using USB-C devices. It offers next-day funds in many cases and seamless setup through the Square Point of Sale app. Best for: businesses that want to extend card acceptance to tablets or laptops with USB-C, without subscribing to a separate terminal. Limitation: does not support chip cards without an additional reader or device; magstripe-only transactions may have different compliance needs in some regions.
Deftun MSR90 USB Magnetic Card Reader

MSR90 is a USB emulation keyboard interface that requires no driver or software installation. It reads up to three tracks and supports ISO7811, AAMVA, CA DMV, and most magnetic card formats. Best for: desktops or laptops needing quick magnetic stripe input without software dependencies. Caution: relies on USB keyboard emulation, which may lack advanced transaction features found in full POS systems.
SumUp Solo — Full Touch Payment Tablet

SumUp Solo combines a full touch interface with mobile data and a free SIM card to ensure payments can be processed anywhere. It emphasizes ease of use, intuitive sales management, and strong connectivity. Best for: mobile vendors and pop-up shops that need reliable payments without depending on Wi-Fi. Limitation: some retailers may require ongoing data plans for uninterrupted operation in remote locations.
SumUp Plus Card Reader — Bluetooth NFC

SumUp Plus provides Bluetooth connectivity for smartphone use, with compatibility for NFC and magnetic stripe payments. It suits sellers who want a compact, mobile-ready setup with a modern interface. Best for: entrepreneurs who prioritize wireless flexibility and quick pairing with a smartphone or tablet. Caution: depends on a compatible mobile device and stable Bluetooth connection for consistent performance.
Buying Guide
What should you consider when choosing a credit card reader?
- Payment methods supported: Decide if you need magstripe, EMV chip, NFC/contactless, or Apple/Google Pay compatibility. Some readers handle all major card types, while others focus on specific formats.
- Connectivity: Choose between USB, Bluetooth, or cellular-enabled devices. Mobile sellers benefit from Bluetooth or cellular devices, while fixed locations may prefer USB-powered readers tied to a POS tablet or computer.
- Mobility vs. permanence: If you operate at a single checkout counter, a terminal like Square Terminal can simplify workflows. For field sales, a compact reader with smartphone integration is often better.
- Fees and terms: Look for transparent rates, no hidden fees, and whether long-term contracts apply. Some brands emphasize flat rates, while others use tiered pricing.
- Setup and maintenance: Consider ease of setup, required apps, and whether the device integrates with your current inventory or accounting software.
- Security and compliance: Ensure PCI alignment and data encryption. Verify that the solution supports secure receipts and compliant data handling.
