The 7 Best Card Readers for Small Businesses (2025 Comparison)

When’s the last time you paid with cash? Chances are, it’s been a while.

In the US, over 214 million adults (which is 82% of the population) have a credit card in their name. On average, they carry nearly three cards and make around 244 credit card payments a year.

To serve them, you'll need a card reader so you can accept credit card payments, accept debit card payments, and accept contactless payments. Card readers let your customers pay how they want and they make sure you get paid fast.

In this guide, we’ll break down the 7 best card readers for small businesses in 2025, plus show you how to pick the right one for your budget, setup, and growth plans. Let’s get into it.

Quick compare: the best small business card readers of 2025

How to choose a card reader: Your 6-point checklist

Okay, so you know you need a card reader. But which one?

It’s easy to get overwhelmed with all the options out there. Some are cheap up front but hit you with hidden fees later. Others look great until you realize they don’t work with the tools you already use.

That’s why this next part matters. We're going to walk you through a checklist so that you have a simple way to figure out what really matters before you buy.

1. Cost & fees

Let’s start with the big one: cost. We understand that small business owners need to keep an eye on their purse-strings. It's no secret that 82% of small businesses fail due to cash flow problems. So when it comes to choosing a card reader for small business, the numbers really matter.

However, it's not just about how much the credit card reader costs up front. You’ve also got to look at the full picture.

There are two main things to look at:

1) The hardware cost – This is the price of the actual credit card reader or mobile card reader, with either purchase or rental costs. Some are cheap, and some are even free. Others might cost more if they come with advanced features.

2) Transaction fees – These are the fees that you pay each time you accept a card payment. Most providers take a small percentage of the sale, plus a flat fee. Some use a pricing model called Interchange+, which can be more detailed but harder to understand.

And then there are the extra costs you don’t always see at first:

• Monthly fees
• PCI compliance fees
• Long-term contracts

These hidden fees can add up quickly, especially when you’re taking credit card payments, debit card payments, or mobile payments like Apple Pay or Google Pay.

2. Integration: 

If your card reader doesn’t connect with your other systems (like your inventory management or sales app for instance) you’ll spend a lot of time doing things twice.

Think about it... Entering sales data by hand, fixing inventory mistakes, and spending extra hours reconciling payments at the end of the day is all wasted time and, in turn, wasted money.

Inventory errors mean you might run out of stock or have too much of something. And all that extra work slows down your payment processing and hurts your cash flow.

This is where a system like Epos Now stands out. It’s an all-in-one device that links your mobile credit card reader (or mobile payment solution), POS system, and inventory tools. When everything integrates, you avoid manual work, reduce mistakes, and get your sales data in real-time.

So when you’re picking a card reader, don’t just think about the hardware (like the machine itself or the barcode scanner) or processing fees. Think about how it fits into your whole setup.

3. Ease of use:

Have you ever bought one of those "easy setup” gadgets, like a smart speaker or a new phone charger, and ended up totally lost? You get home, open the box, and suddenly you’re tangled in wires or stuck on some confusing app.

Well, picking a card reader for your business can feel the same way if it’s not straightforward.

Some mobile card readers are as simple as pairing via Bluetooth to your phone or tablet—quick and painless. Others need you to plug into a cash drawer, connect with your Wi-Fi, or get familiar with a whole new system.

And then there’s the software itself. If the app or interface isn’t user-friendly, you’ll spend more time troubleshooting than actually being able to accept card payments.

So, find a card reader that’s easy to get going and easy to use every day with an intuitive interface and smart terminal. Because the less time you spend fumbling, the more time you have to focus on customer experiences and that'll result in more customers and more sales.

4. Accepted payment types

When you pick a card reader for your small business credit card processing, you want to make sure it can accept all the main ways people pay. We call this payment flexibility and it's important.

If you've ever walked into a store and asked if they accept AMEX, for instance, only to hear, “Sorry, no,” you know how frustrating that can be. The same goes for your customers. You want to avoid turning people away just because you can’t accept their chosen payment method.

At the absolute minimum, your new card reader needs to work with EMV chip cards (for chip payments). These are the cards with a small metal chip on the front. When customers insert their card, the chip helps keep the payment safe and secure. Most people have these cards now so you need to accept chip.

Your card reader should accept contactless payments and mobile wallets. Customers swipe, sure, but the modern-day customer likes to pay on their phone or on their Apple watch. This is called NFC technology (near field communication) and in the States, more than half of Americans are now using some form of contactless payment on mobile devices or apps like Apple Pay, Google Pay, or Samsung Pay (using Android devices). So enable tap payments.

Finally, your reader should still accept magstripe cards with a magnetic stripe. These are the cards you swipe through a slot. Not everyone uses them anymore, but some customers still do so having this option is a good backup.

5. Security & PCI compliance

PCI stands for Payment Card Industry. PCI compliance means you follow rules that keep your customers’ payment information safe.

If you don’t follow these rules, your payment provider might charge you extra fees, which is usually between $10 and $100 each month. But the real risk is a data breach, where someone steals payment info. That can cost your business thousands of dollars, sometimes $5,000 to $100,000 per month.

The good news is that your card reader provider should handle most of the PCI compliance for you. You don’t have to worry about it all by yourself.

Choosing a card reader with strong security and built-in PCI compliance helps keep your business safe, your customers’ data protected, and guarantees you're taking secure transactions.

6. Support & reliability

When you run a small business, especially one open outside the usual 9 to 5, you need support you can count on, anytime.

That’s why 24/7 customer support is so important. If your card reader or payment system stops working late at night or on weekends, you don’t want to wait hours or days for help.

Good support means you can get back to accepting payments quickly, keeping your customers happy and your business running smoothly.

Also, check if your card reader comes with a hardware warranty. This protects you if the device breaks or stops working, saving you money on repairs or replacements.
