The best mobile credit card readers have positive user reviews on customer review sites and app stores. Mobile credit card reader providers should provide customers with fast and reliable support. Using a combination of phone support, live chat and knowledge bases, customers should be able to quickly resolve issues 24/7.

Mobile credit card readers should allow companies to accept mobile and contactless payments as well as offer self-service capabilities for customers to check themselves out. Hardware should integrate with robust software and apps that allow users to manage numerous aspects of their business, including inventory management, reports and analytics, loyalty programs and gift card management.

And the best mobile credit card reader providers should offer affordable or free equipment to help businesses begin accepting payments quickly and easily.

What are mobile credit card readers, and how do they work?

A mobile credit card reader lets employees accept payments at the table, curbside or at the customer’s home. It’s a portable standalone device or a small dongle that attaches to a cell phone or tablet through a headset jack, lightning connector or Bluetooth. 

After entering the transaction amount, the user swipes, dips, inserts or taps the customer’s credit card. Bluetooth-enabled (BLE) models also support contactless payments. 

Depending on the credit processor, a signature may be required. Post-sale, the customer receives a receipt by email or text. Alternatively, retailers and restaurateurs may use standalone mobile credit card readers. These devices do everything a cell phone-based reader does but don’t require a separate phone or tablet.

How to choose the best mobile credit card reader for your business

Mobile card readers (and the associated POS software) can help your company add a new income stream or accept curbside payments. However, a complex user interface or high processing fees may restrict growth. Use these tips to find the right mobile credit card reader for your business.

Assess mobility use cases, budget and goals

A solopreneur wanting a mobile solution for a small startup has different needs than an established retailer looking to add local delivery and curbside services. Likewise, if you already have Apple products, you’ll want the best credit card readers for iPhones. Think about your current and future business needs before choosing hardware.

Consider the following questions:

  • What is your monthly budget for POS software?
  • How many mobile credit card readers do you need?
  • Do you require compatibility with existing cell phones or tablets?
  • How much can you spend upfront for mobile equipment?
  • Will you process payments while offline?
  • Are e-commerce, accounting or social media integrations vital?
  • Do you only want an in-store solution or an online POS or e-commerce solution, too?
  • What industry-specific features are you looking for?
  • Do you expect your company to expand quickly?

Once you understand your business requirements, it’s time to find solutions. Aside from guides like this one, check out reviews of POS software, e-commerce services and credit card processing systems.

Only Square offers a no-strings-attached mobile card reader. As long as you sign up for a free account, they’ll send you free hardware. However, this reader doesn’t take contactless payments or provide the extra security features of chip readers. Other vendors, like Clover POS, may include free equipment with the purchase of certain POS software subscriptions. 

Mobile card readers for cell phones and tablets range from $10 to $99. Square’s magstripe dongle is the cheapest, whereas Lightspeed’s Chipper 2X BT is the most expensive. 

Aside from upfront costs, merchants may have recurring POS subscription fees ranging from $1 to $2,000 monthly. The vendors we reviewed charge flat rate transaction fees. Pricing is relatively similar between providers and may vary by plan. 

Frequently asked questions (FAQs)

Mobile card readers have upfront and ongoing costs. One-time fees include the costs of buying the hardware, shipping and taxes. Some vendors offer free equipment, and paid card readers start at $10.

Ongoing costs consist of monthly POS subscriptions if you opt for a paid plan. However, Square has a free version. You’ll also pay a per-transaction fee. This varies by vendor and subscription tier.

Square’s mobile card readers earn high ratings for their affordability and ease of use. Small businesses can choose between free or paid models and take advantage of Square’s built-in POS tools, active fraud prevention and end-to-end encrypted payments.
