Customers are gradually reducing cash payments and switching to pay by cards or e-wallets. Thus, it’s important for retailers to equip their stores with a high-quality credit card reader.

There are certainly a lot of things to consider when choosing a credit card reader brand, whether it’s your first time buying a credit card processor or you’re upgrading your old credit card readers. If you want to know what are the best credit card processors for retail in 2021, we’ve compiled a list of the top 5 card readers for your business based on their popularity and specifications.

Let’s keep reading our reviews to understand the pros and cons of each brand.

What is a credit card reader?

A credit card reader is a device that can decode the debit and credit card information stored in a microchip or a magnetic stripe of the cards to accept payments, including:

  • Cardholder information
  • Account number
  • Authorization code
  • Card expiration date

Today, credit card readers can electronically scan that information. In the past, you had to rely on a physical copy in a “knuckle cracker” to extract the necessary information from a customer’s card. As the name implies, users will have to scrape their knuckles onto the device to create their copies. Today, merchants still use this type of device as a backup when the electronic credit card processor fails.

How do credit card readers work?

Credit card readers are the connection parts in the payment networks, which are normally used at the ATMs of the banks or the POS terminals of retail stores.

  • When customers dip or swipe their cards, the credit card reader will decode the encrypted information and transmit it to the customer’s issuing bank for authorization.
  • The issuing bank will review if the card is involved in fraud or qualifies for the transaction (whether the account has sufficient cash or credit to complete the payment).
  • If the cardholder’s account has no problem, the issuing bank will pass their approval to the POS system and authorize the transaction.

The transaction process sounds complicated and involves many parties, but the modern card reader technology helps merchants complete these steps instantly in just a few seconds.

Types of credit card readers

1. Countertop credit card readers

Countertop credit card reader is ideal for retailers that sell products and accept payments in-store.

Countertop credit card readers


These are the cheapest kind of credit card processors and have the fastest payment processing speeds.

  • Connected to your broadband line or phone, it can process the payment in a second.
  • Connected to the mains power, it’s always ready to go and no need to worry about the device running out of battery or recharging them.


  • The only disadvantage of the countertop credit card readers is that due to the wired connection, you can’t move them. Depending on your business operations, this may or may not be an issue.

2. Portable credit card readers

A portable credit card reader is the best choice for merchants who want to accept payment at the customer’s desk. As a result, customers can continue to enjoy their quality time like dinners or romantic dates without interruption. Portable credit card readers are not much more expensive than countertop credit card readers – a reasonable choice for small and medium businesses.

Portable credit card readers


Portable credit card readers give merchants more room to move around when accepting payments.


To process payments, you need to be within scope because there is still a limit of mobility from the device’s Bluetooth connection.
You need to monitor the battery to ensure it doesn’t run out of power at a critical moment.

3. Mobile credit card readers

Without a cable or wired network connection, mobile credit card readers can accept payments anywhere as long as there is a 3G mobile signal. These are great options for:

  • New businesses who haven’t got a merchant account yet
  • Small businesses who need a lightweight and simple POS
  • Mobile businesses like personal trainers, mobile dog groomers, and food trucks
  • Any service businesses that need to visit their customers at home and perform services like delivery, contractors, exterminators, and plumbers
Mobile credit card readers


Flexibility and convenience are clear benefits of mobile credit card readers for the following sales situations:

  • Mobile sales such as occasional craft fairs, farmer’s markets, and pop-up shops
  • Event sales
  • Traveling sales
  • Selling floor


Compared to desktop and portable devices:

  • The price of a mobile credit card reader is significantly higher.
  • The payment processing speed is slightly slower depending on mobile network speed.

There are some important aspects to consider the best credit card reader for your business:

  • Ease of use
