More Details on Our Top Picks
SumUp Plus Card Reader, Bluetooth, NFC RFID Credit Card Reader for Smartphone
The SumUp Plus Card Reader shines for its ability to accept all major credit and debit cards through NFC and RFID technology, making it highly versatile for mobile transactions. Unlike the Square Reader for Magstripe, it supports contactless payments, which many customers now prefer. Its Bluetooth connectivity works seamlessly with smartphones and tablets, offering a straightforward, no-contract experience. However, the transaction fee of 2.6% + 10¢ can add up quickly for high-volume businesses, and it depends entirely on your mobile device for operation. Compared to the Square Reader for Magstripe with Lightning, which only accepts magstripe cards, the Plus offers broader payment options at a slight cost, making it ideal for those needing flexibility with minimal setup. The tradeoff revolves around paying a higher fee for the convenience of contactless payments.
Pros:- Supports all major credit and debit cards via NFC and RFID
- No hidden fees or long-term contracts
- Portable and easy to use with smartphones or tablets
Cons:- Transaction fee of 2.6% + 10¢ may be expensive for high sales volume
- Requires a compatible smartphone or tablet for operation
Best for: Small business owners or mobile vendors who need broad payment acceptance, including contactless transactions.
Not ideal for: High-volume merchants seeking the lowest possible transaction fees or those who prefer integrated POS systems without relying on a smartphone.
- Connectivity:Bluetooth
- Payment Technology:NFC, RFID
- Compatible Devices:Smartphones, Tablets
- Transaction Fee:2.6% + 10¢
Our verdict“This device suits mobile vendors who prioritize broad payment options and convenience over transaction costs.”
Square Reader for Magstripe with Lightning Connector
The Square Reader for Magstripe with Lightning Connector offers a straightforward way to accept swipe cards on compatible iOS devices, making it ideal for quick, no-frills transactions. Unlike the SumUp Plus, it only supports magstripe cards, which limits future-proofing but keeps costs lower for businesses that still rely on swipe payments. Its seamless integration with Square’s POS app allows for digital receipts, sales tracking, and instant deposits—features that make it a strong choice for small retail setups. The major tradeoff is that it doesn’t support chip or contactless payments, which can be a drawback in more modern or security-conscious environments. Also, it requires a Lightning port, so it’s incompatible with newer iPads without adapters. Compared to the Square Reader for Magstripe (USB-C), this model is more portable but less versatile in card acceptance.
Pros:- Easy integration with Square POS apps
- Supports multiple major credit cards via swipe
- Allows digital receipts and sales tracking
Cons:- Limited to magstripe cards, no chip or contactless support
- Requires a Lightning port, limiting compatibility with newer devices
Best for: Small businesses using iOS devices that primarily process swipe credit cards and need quick deployment.
Not ideal for: Businesses that want contactless or chip card support, or owners with Android devices, as this model is limited to Lightning-compatible iOS devices.
- Compatibility:iOS devices with Lightning connector
- Payment Types:Magstripe credit cards
- Deposit Time:1-2 business days or instant (fees apply)
Our verdict“This reader is ideal for iOS users who mainly process swipe payments and value simple integration over card technology variety.”
SumUp Solo Credit Card Payment Card Reader with Charging Station
The SumUp Solo stands out for its integrated full touch-screen interface, making it a portable all-in-one solution for mobile sales compared to standalone magstripe readers like Square’s USB-C or headphone jack options. Its support for free SIM card and mobile data offers reliable connectivity, ideal for vendors who need to process payments in locations without Wi-Fi. While it does include a charging station and a compact design, its limited printer functions mean it’s not suitable for high-volume receipt printing. Its battery life can vary based on usage, which might be a concern for all-day transactions. Compared to the more basic Square Magstripe options, the Solo provides a more comprehensive experience, but at a higher price point and with added complexity.
Pros:- Portable with a full touch-screen interface
- Includes free SIM card and mobile data for flexible payments
- Built-in charging station prolongs usability
Cons:- Primarily designed for printing receipts, with limited printing functions
- Battery life can vary and may require frequent charging during busy periods
Best for: Mobile entrepreneurs or event vendors who want a standalone device with a touchscreen and on-the-go connectivity.
Not ideal for: Businesses primarily needing barcode scanning or extensive printing capabilities, or those with limited budget, as it’s a more premium device.
- Display Type:OLED
- Display Resolution:200 x 200 dpi or 300 x 300 dpi
- Connectivity:Wi-Fi, mobile data (SIM included)
- Includes:Charging station
Our verdict“This pick is best for mobile vendors seeking an all-in-one device with intuitive controls and reliable connectivity on the go.”
Square Reader for Magstripe (USB-C)
The Square Reader for Magstripe (USB-C) offers a quick setup for accepting swipe cards on Apple devices with USB-C ports, making it more flexible than the Lightning version. It integrates seamlessly with Square’s POS system, supporting sales management and digital receipts. Compared to the headphone jack model, it benefits from a more modern connection, but both are limited to magstripe cards, which restricts future payment options. This model is well suited for businesses that prefer a wired connection for stability and use newer MacBooks or USB-C equipped iPads. The main tradeoff is that it still doesn’t support chip or contactless payments, which are increasingly standard. Its reliance on Square’s ecosystem means businesses must commit to their platform.
Pros:- Easy to set up and use
- Compatible with Apple devices via USB-C
- Integrates with Square POS for comprehensive management
Cons:- Limited to magstripe cards, no chip/contactless support
- Requires a Square account and app for full functionality
Best for: Apple device users who want a stable, wired magstripe reader for quick, reliable swipe transactions.
Not ideal for: Businesses needing contactless or chip card support, or owners looking for a device with integrated chip reading capabilities.
- Compatibility:Apple devices with USB-C
- Connectivity:USB-C
- Features:Magstripe reader
- Integration:Square POS app
Our verdict“This reader makes sense for Apple users seeking a wired, reliable swipe payment solution with seamless Square integration.”
Square Reader for Magstripe (Headphone Jack)
The Square Headphone Jack Magstripe Reader offers a simple, no-charging way to accept swipe cards on many older Android and iOS devices, making it a practical choice for budget-conscious or legacy system users. Unlike the SumUp Plus or newer Square models, it requires a device with a 3.5 mm headphone jack, limiting its compatibility with modern smartphones. It supports all major credit and debit cards via swipe, but doesn’t handle chip or contactless payments, which could be a drawback as card technology evolves. Its plug-and-play setup and lack of power requirements make it very accessible, but the limited functionality restricts its use in more advanced retail environments. Compared to the USB-C version, it’s less versatile but perfect for those with compatible devices needing a straightforward swipe solution.
Pros:- Accepts all major cards via swipe
- No charging needed, plug-and-play simplicity
- Compatible with many popular mobile devices
Cons:- Requires a device with a 3.5 mm headphone jack
- Limited to magstripe transactions only
Best for: Small businesses or vendors using older smartphones with headphone jacks that need a simple, low-cost swipe solution.
Not ideal for: Businesses that want to accept chip or contactless payments, or those with newer smartphones without a headphone jack.
- Compatibility:Devices with 3.5 mm headphone jack
- Payment Types:Visa, Mastercard, Discover, Amex
- Power:No charging needed
Our verdict“This option fits legacy device users who need a basic swipe reader without extra features or costs.”
Square Terminal – Credit Card Machine to Accept All Payments | Mobile POS
The Square Terminal stands out for its comprehensive all-in-one design, combining payment acceptance, receipt printing, and a cordless form factor. Compared with the Square Reader for Contactless and Chip, it offers a more integrated experience, eliminating the need for separate devices. Its built-in battery and fast chip processing ensure quick transactions on the go, which is ideal for busy businesses. However, its larger size and the requirement for a subscription to Square’s service might deter casual users or small-scale sellers. This device makes the most sense for small retail outlets or food vendors needing a portable, multi-functional terminal with minimal setup. The limited detailed user reviews suggest some uncertainty about long-term reliability, and the costs of ongoing service fees are a consideration for tight budgets.Pros:- All-in-one device combining payments and receipts
- Accepts all major credit and debit cards
- Cordless with a long-lasting built-in battery
- Fast chip card processing in two seconds
Cons:- Limited detailed user reviews available, making long-term reliability uncertain
- Requires a subscription to Square services for full features
Best for: Small retail shops and mobile vendors who want a versatile, all-in-one payment solution with receipt printing.
Not ideal for: Casual sellers or hobbyists who prefer a simple, inexpensive card reader without subscription commitments.
- Product Dimensions:5.6 x 3.4 x 2.5 inches
- Item Weight:14.7 ounces
- Manufacturer:Square
- Batteries:1 Lithium Ion batteries required (included)
- Date First Available:February 12, 2019
Our verdict“This pick is best for small businesses seeking a portable, multifunctional POS with quick transaction speeds.”
Square Reader for Contactless and Chip (2nd Generation)
The Square Reader 2nd Generation is a compact, highly portable device that excels at accepting contactless payments and chip cards, making it ideal for quick, secure transactions in various settings. Unlike the Square Terminal, which offers a full POS experience, this reader focuses solely on payment acceptance, which suits businesses that already have a POS system or prefer a minimal hardware footprint. Its improved connectivity and extended battery life make it reliable for on-the-go use, but it doesn’t support magstripe payments, limiting its versatility for some users. It’s perfect for merchants who mainly process contactless or chip payments and want a lightweight, no-fuss device. However, users must have a compatible device to operate it, and poor signals can cause connectivity hiccups, especially in remote locations.Pros:- Accepts multiple payment methods including contactless and chip cards
- Enhanced connectivity and security features
- No monthly fees or long-term commitments
- Offline payments supported for up to 24 hours
Cons:- Requires a compatible device for operation, adding dependency
- Limited to contactless and chip card payments; no magstripe support
- Potential connectivity issues in areas with poor signal
Best for: Event vendors, food trucks, or service providers who need a small, secure contactless payment device that doesn’t require a dedicated POS terminal.
Not ideal for: Businesses that still rely on magstripe payments or need an all-in-one POS solution, as this device doesn’t support magstripe or receipt printing.
- Payment Types:Contactless, Chip Cards, Apple Pay, Google Pay
- Connectivity:Enhanced connectivity with stays paired feature
- Battery Life:Extended battery life
- Security:Data security, 24/7 fraud prevention, payment-dispute management
- Offline Payments:Up to 24 hours
Our verdict“This device is ideal for mobile merchants who prioritize contactless and chip payments in a compact, secure form factor.”

Factors to Consider When Choosing Mobile Card Readers
Choosing the right mobile card reader involves evaluating several important factors. Beyond basic compatibility, consider how each device fits into your existing payment ecosystem, your typical transaction environment, and your budget. Failing to match a reader’s capabilities with your needs can lead to inefficiencies or additional costs. The following sections highlight key considerations to help clarify your decision.Compatibility and Connectivity
Most mobile card readers connect via Bluetooth, USB-C, or headphone jack, so it’s crucial to match the device with your smartphone or tablet. Bluetooth models offer wireless convenience but may experience interference; wired options can be more stable but less flexible. Also, check if the reader is compatible with your operating system, whether iOS or Android, to avoid integration issues.
Payment Method Support
Consider which payment types you’ll process most often. Magstripe readers are generally cheaper but less secure, while chip and contactless NFC readers provide more security and are increasingly necessary as consumer preferences shift. Opting for a device that supports multiple methods ensures you won’t need to upgrade prematurely as payment standards evolve.
Ease of Use and Setup
An intuitive interface and quick setup process reduce transaction times and minimize frustration. Devices with clear instructions, straightforward app integration, and minimal configuration are especially valuable for small businesses or those new to mobile payments. Remember, a complex setup can slow down your sales process.
Durability and Portability
If you operate in mobile environments—markets, events, or on-site services—look for lightweight, rugged models that can withstand travel and outdoor conditions. Compact designs that easily fit in pockets or bags help keep your workflow efficient and hassle-free.
Pricing and Long-Term Costs
While some devices are inexpensive upfront, consider ongoing costs such as transaction fees, monthly service charges, or replacement parts. Balance your initial investment against the volume of transactions to determine what offers the best overall value. Sometimes spending a bit more initially can save money in the long run through better durability or more features.
Frequently Asked Questions
Can I use a mobile card reader with multiple devices?
Many mobile card readers support pairing with multiple devices via Bluetooth or wired connections, but often only one device can be connected at a time. Check the specific model’s specifications to see if it allows multiple pairings or easy switching. This flexibility can be useful if you operate across different smartphones or tablets without needing separate readers.
What should I do if my card reader isn’t working properly?
If your mobile card reader malfunctions, start by checking the connection and ensuring the device’s firmware and app are updated. Restarting your device or re-pairing the reader often resolves connectivity issues. If problems persist, consult the manufacturer’s troubleshooting guide or contact support—many issues are fixable with simple steps, but persistent faults may require a replacement.
Are wireless card readers secure enough for sensitive transactions?
Most reputable mobile card readers incorporate encryption and comply with PCI standards to protect sensitive payment data. Devices supporting contactless and chip transactions generally offer higher security than magnetic stripe options. For added peace of mind, choose readers with built-in security features and ensure your payment app is up to date, reducing the risk of data breaches.
How do I handle transactions if my internet connection drops?
If your internet or Bluetooth connection drops during a transaction, some mobile readers can store transaction data locally and process it once reconnected. However, this feature varies by model. To avoid interruptions, ensure your device has a stable connection and consider a reader with offline capabilities if offline sales are frequent. Always verify how each device manages such situations before purchasing.
Is it worth investing in a more expensive mobile card reader?
Investing in a higher-priced device often means better build quality, broader payment method support, and enhanced security features. If your business processes a high volume of transactions or requires reliable, fast payments, spending more on a premium model can improve efficiency and reduce downtime. For low-volume or casual use, a more affordable option might be sufficient, but weigh the long-term benefits against the initial cost.
Conclusion
For small businesses prioritizing overall reliability and versatility, the SumUp Plus Card Reader offers an excellent balance of features. Those seeking affordability and simplicity may prefer the Square Reader for Magstripe, especially for occasional use. If you need a full mobile POS system, the Square Terminal provides an all-in-one solution for higher transaction volumes. Beginners or infrequent users should lean toward straightforward, plug-and-play devices, while established merchants handling diverse payment methods will benefit from investing in models supporting contactless and chip payments. Match your choice with your specific operational needs and budget for the best results.Halloween Picks
