How Do Card Readers Work? Tap vs Swipe vs Dip

Smooth, seamless payments via card readers help distinguish your business from the competition. Whether you’re running a small boutique or the sales department of a large enterprise, grasping the mechanics of card readers is crucial for ensuring a hassle-free checkout experience.

In this guide from Payment Nerds, we’ll explore the different types of credit card readers, how they work, and the various ways they can benefit your business.

What Are Card Readers?

A card reader is a device that enables merchants to accept and process payments from credit and debit cards^[1]. It links the customer’s card to the payment processor, quickly exchanging payment details and authorization. This device also ensures secure credit card processing so funds can be transferred safely to your business account.

Today’s card readers offer more than just the basic “swipe and go.” They support both card and contactless payments, including chip reading, “Tap to Pay” features, and integration with digital wallets. Card readers can function as standalone devices or as part of a point-of-sale system.

Depending on your business’s requirements, you can select a payment solution that fits your goals, budget, and customer preferences.

How Do Card Readers Work? 

Card readers work by securely transmitting payment information from the customer’s card to the payment processor. Here’s a step-by-step breakdown:

1. Card Interaction: The customer either taps, dips, or swipes their card through the reader. For tap payments, the card utilizes near-field communication (NFC) technology. When dipping, the chip is read, and for swiping, the magnetic stripe is scanned.
2. Encryption: The card reader encrypts the payment data to safeguard it from unauthorized access.
3. Data Transmission: The encrypted data is sent to the payment processor, which verifies the transaction details with the card’s issuing bank.
4. Approval: Once approved, the transaction amount is deducted from the customer’s account and transferred to the merchant’s account.

This entire process occurs within seconds, making electronic payments efficient and convenient for both businesses and customers.

What Types of Card Readers Are Available?

No matter the type or size of your business, there’s a card reader to match your needs. Here are three main categories to look for:

 

Countertop Card Readers

You’ll usually find these traditional credit card readers in brick-and-mortar stores. They are often fixed in place and connected to a point-of-sale terminal, though they can also operate through a phone line or internet connection^[2].

Modern countertop readers typically accept all card payment methods, including swiping, dipping, and tapping. They’re also ideal for businesses with permanent locations, such as retail shops and restaurants.

Mobile Card Readers

Mobile card readers are often mobile devices that connect to your smartphone or tablet. They can process payments through virtual terminals or retail payment gateways^[2].

These devices are perfect for businesses on the move, like food trucks, pop-up shops, and service professionals. Mobile readers also offer unmatched flexibility, enabling you to accept payments anywhere.

Integrated POS Card Readers

These readers are seamlessly connected to a POS system. They can be attached to mobile devices or integrated into point-of-sale terminals, allowing customers to pay by swiping, tapping, or inserting their cards.^[2].

An integrated POS card reader merges payment processing with additional features like inventory management and sales tracking. It has become common in medium to large-sized businesses that rely on efficiency and data analysis.

What Ways Can You Make Payments Using Card Readers?

Card readers accommodate a variety of payment methods to meet different customer needs. Here’s a close look at each card payment method:
