Best credit card reader for small business in 2026
Retail, food truck or service business: five card readers compared on what they cost at your volume, not on the sticker price.
The short answer: Square is the best credit card reader for most small businesses. It costs $0 a month, charges 2.6% + 15¢ per in-person payment, and comes with a free point of sale you can grow into. Helcim, second, is the cheapest once you process real volume: no monthly fee, and only 0.40% + 8¢ on top of interchange below $50,000 a month. PayPal POS has the lowest flat rate, 2.29% + 9¢, and a $29 reader. Stripe Terminal is for shops that already run on Stripe and have a developer. We compared five readers on fees, hardware, payout speed, contracts and support, with the math worked out at $3,000 and $8,000 a month in card sales.

The 5 credit card readers compared
The full ranking. The pricing model column matters as much as the rate: a flat rate is the same on every card, interchange-plus passes the card network's cost through. Prices come from official pages. Scores are the same on every page we publish, including our ranking of POS systems.

Scores on five card-reader criteria. Prices read on official pages in 2026; in-person rates for US cards.
How we compared and scored
A credit card reader costs you three ways: the hardware once, a fee on every sale, and the days your money spends in transit. Most reviews focus on the first. We priced the second at two volumes, $3,000 and $8,000 a month in card sales with a $25 average ticket (120 and 320 payments), and checked the third for every provider.
For each reader, we read pricing, hardware and payout terms on the official vendor pages in 2026, then read merchant reviews, starting with the worst: frozen funds, dead readers, support that never calls back. Overall scores are the same across our pages, so Square, PayPal POS and Clover keep the score from our POS rankings. Helcim and Stripe Terminal are scored here for the first time. SumUp also sells readers in the US, but we couldn't confirm its US rates on an official page, so it isn't ranked. Running a restaurant? Look at a restaurant POS such as Toast instead: table service needs more than a card reader. We didn't open accounts with any vendor: we compared what they publish and what their customers report.

Square
Square charges 2.6% + 15¢ per in-person payment on its Free plan, which costs $0 a month. There's no contract and no monthly minimum. At $3,000 a month in card sales, you pay about $96 in fees; at $8,000, $256 (our math, $25 tickets).
What puts Square first isn't the rate: PayPal POS is cheaper per swipe. It's everything around the reader. The free point of sale handles items, inventory, receipts and simple reports, and paid plans at $49 and $149 a month per location add more as you grow. You can start with a small reader and move to a countertop register without switching providers or retraining staff. If you later need a full register for a store, our convenience store POS ranking shows how Square stacks up there.
The catch is the fixed 15¢. On small tickets it adds up: on a $5 coffee, you pay 5.6% in fees. Like every aggregator, Square can hold payouts it flags as risky, so keep a cash buffer when your volume jumps. Square is also a flat-rate aggregator, so past $10,000 a month you're probably overpaying.
- Free POS included with the reader
- No contract, no monthly minimum
- Paid plans per location as you grow
- Hardware lineup from reader to register
- ✓Easiest start of the ranking
- ✓Grows into a full POS without switching
- ✓Same rate on every card brand
- ✗15¢ fixed fee hurts small tickets
- ✗Can hold payouts it flags as risky
- ✗Overpriced past $10K a month
The best reader for most small businesses starting out. Not the cheapest once you pass about $10,000 a month in cards, or if your tickets are under $10.
Helcim
Helcim doesn't charge a flat rate. It passes through interchange (the fee the card networks set) and adds a markup: 0.40% + 8¢ per in-person payment below $50,000 a month, falling as your volume grows, down to 0.15% + 6¢. There's no monthly fee, no contract and no cancellation fee. Helcim says merchants usually land near or below 2% overall.
On $8,000 a month in 320 sales, Helcim's markup is $57.60 (our math), plus interchange. On a debit-heavy card mix, interchange is low and the total beats every flat rate in this ranking. On premium rewards cards, interchange climbs, and the edge shrinks. That's why we can't give one number: ask Helcim to estimate a statement with your real mix.
The catch is the hardware. The Card Reader costs $199 and the Smart Terminal $349, or $32 a month on a one-year plan. That's more than Square or PayPal up front. And interchange-plus statements are harder to read. If you want one rate you never think about, this isn't it.
- Interchange-plus with a 0.40% + 8¢ markup
- No monthly fee, no contract, no cancellation fee
- Markup drops as volume grows
- Smart Terminal on a $32/mo plan
- ✓Lowest total cost past roughly $10K a month
- ✓Debit cards get much cheaper
- ✓Transparent pricing model
- ✗$199 reader, pricier than flat-rate rivals
- ✗Statements are harder to read
- ✗No single number to compare before signup
The best pick once you process serious volume and want to stop overpaying on debit cards. Too much hardware cost for a side business doing $500 a month.
Stripe Terminal
Stripe Terminal charges 2.7% + 5¢ per in-person payment. The low fixed fee helps on small tickets: on a $5 sale, you pay 3.7%, against 5.6% at Square. International cards add 1.5%. At $3,000 a month, you pay $87; at $8,000, $232 (our math).
The hardware is solid: the M2 reader costs $59 and the S700 smart terminal $299. Tap to Pay works on iPhone and Android for an extra 10¢ per payment. The real strength is the single account: online and in-store sales, refunds and customers in one dashboard.
The catch: Stripe Terminal isn't plug and play. You need a point of sale that supports it, or a developer to build with Stripe's tools. For a solo shop owner without one, the reader is useless out of the box.
- 2.7% + 5¢ in person
- Tap to Pay on iPhone and Android
- Readers from $59 to $299
- Online and in-store sales in one account
- ✓Low fixed fee for small tickets
- ✓Unified online and in-person reporting
- ✓Professional hardware
- ✗Needs a developer or a compatible POS
- ✗+1.5% on international cards
- ✗Tap to Pay costs 10¢ more per sale
The right choice if your business already runs on Stripe. The wrong one if you just want to take a card at the counter tomorrow.
PayPal POS
PayPal POS, formerly Zettle, has the lowest flat rate in this ranking: 2.29% + 9¢ per in-person payment, with no monthly or setup fees. Your first reader costs $29, extra readers $79. The Terminal costs $199, or $239 with a built-in barcode scanner. At $3,000 a month, fees come to $79.50; at $8,000, $212 (our math). That's $44 a month less than Square at the higher volume.
Money lands in your PayPal balance within minutes, and transfers to your bank are free. If you already sell online with PayPal, you see every sale in one place.
So why fourth? The point of sale is thinner than Square's, merchants describe support that's hard to reach, and the payout goes to PayPal first, not to your bank. PayPal's account reviews and holds are a frequent complaint among sellers.
- 2.29% + 9¢, lowest flat rate here
- $29 first reader
- No monthly or setup fees
- Funds in PayPal within minutes
- ✓Cheapest flat rate at any volume
- ✓Cheap hardware
- ✓Online and in-person sales together
- ✗Money lands in PayPal before your bank
- ✗Thinner POS than Square
- ✗Support hard to reach
The cheapest flat rate for sellers already using PayPal. Pick Square instead if you want a fuller POS and payouts straight to the bank.
Clover
Clover makes some of the best-looking card readers and countertop terminals on the market, from the small Clover Go to full stations. That's where its score comes from. The rest is harder to judge, because Clover is sold both directly and through banks and resellers, each with its own pricing and terms. The official pricing page we tried to read didn't show its rates.
The lineup runs from the Clover Go reader to the Flex handheld and the Mini countertop terminal. Some reseller deals come with multi-year contracts, so the terms depend on who sells it to you. Hardware bought through one processor can't always move with you to another.
If your bank offers Clover, ask for the processing rate, the monthly fee, the contract length and the early termination fee in writing. Compare that total with Square and Helcim over twelve months.
- Wide range of countertop and handheld devices
- Sold directly or through banks
- From pocket reader to full station
- ✓Polished, reliable hardware
- ✓Works with many banks
- ✗Pricing not shown on the page we read
- ✗Terms vary by reseller
- ✗Harsh merchant reviews on fees and contracts
Great hardware, murky pricing. Only worth it if your bank's written offer beats Square and Helcim over a year.
What a card reader really costs you each month
The reader is a one-time cost. The fees hit every month. Here's what you pay in processing on $3,000 and then $8,000 a month in card sales, with a $25 average ticket (120 and 320 payments). Our math, from official rate cards, for US cards in person.
- PayPal POS at 2.29% + 9¢: $79.50, then $212.
- Stripe Terminal at 2.7% + 5¢: $87, then $232 ($12 and $32 more with Tap to Pay).
- Square at 2.6% + 15¢: $96, then $256.
- Helcim markup at 0.40% + 8¢: $21.60, then $57.60, plus interchange, which depends on your card mix.
At $8,000 a month, the gap between Square and PayPal POS is $44 a month, or $528 a year: more than any reader in this list. Past $10,000 a month, get a statement estimate from Helcim on your real card mix before you decide.

Frozen funds, leases, surcharges: the card reader traps
Most reviews compare stickers. Merchants complain about money that doesn't arrive, contracts they can't leave and readers that go silent at the worst moment. Here are eight points from their stories.
Avoid frozen funds
Cash flowFrozen payouts are the top complaint against flat-rate processors. The trigger is almost always a risk review: a sudden spike in volume, a ticket far above your usual, or a business type the processor didn't expect.
What helps: describe your business exactly at signup, upload every verification document on day one, and message support before a big event or a large invoice. Don't leave weeks of revenue in a processor wallet; move it to your bank on a schedule.
- Habit
- Move funds to your bank weekly
When interchange-plus beats a flat rate
MathA flat rate bundles the card network's cost and the processor's margin. Interchange-plus splits them. On debit cards, interchange is low, so interchange-plus is much cheaper. On premium rewards cards, it's higher.
The rule of thumb: once you pass about $10,000 a month, or if most customers pay with debit, ask for an interchange-plus quote. Compare effective rate (total fees divided by sales) on a real month.
- Helcim markup
- 0.40% + 8¢ below $50K/mo
Never lease a terminal without reading the exit
ContractA free terminal with a multi-year lease is the oldest trap in card processing. The lease often can't be cancelled even if you close the business, and it outlives the processor contract.
Before signing anything with a bank or reseller, get the contract length, the early termination fee and the total cost over the term in writing. None of the readers ranked here require a lease.
- Ask for
- Early termination fee, in writing
The fixed fee matters more on small tickets
MathA coffee shop and a furniture store shouldn't pick the same reader. On a $5 ticket, Square's 15¢ adds 3 points on top of the 2.6%, for 5.6% total. Stripe's 5¢ keeps it at 3.7%, PayPal POS's 9¢ at 4.1%.
Divide your monthly card sales by your number of transactions. If your average ticket is under $15, compare fixed fees first.
- $5 ticket at Square
- 5.6% in fees
Passing fees on to customers
RulesAdding a card fee to the bill looks like an easy way to protect your margin. But surcharge rules depend on your state and on the card networks, and they don't treat credit and debit the same way.
Read your state's rules and ask your processor before adding a surcharge line. If the rules are unclear where you sell, a small cash discount gets you most of the benefit with less risk.
- Safer option
- A cash discount
Offline payments come with risk
HardwareSome readers can store payments when the signal drops and process them later. The risk is yours: if a stored card is declined when the reader reconnects, you lose the sale.
At markets and events, test your signal before opening, set a low limit for offline payments if your reader allows it, and keep a backup phone on another carrier.
- Test
- A $1 payment on site
Tap to Pay: great backup, not a main reader
PhoneTap to Pay on iPhone and Android needs no hardware. It's ideal for pop-ups and as a backup when the reader dies. At Stripe, it costs 10¢ more per sale: $12 a month on 120 payments.
It drains your phone battery and can't read a chip card with a PIN. Past a few dozen sales a day, keep a real reader on the counter.
- Stripe add-on
- +10¢ per payment
Know how to reach support before you need it
ReliabilityEvery provider here gets complaints about support: long waits, chat-only answers, nobody on the phone on Saturday night. Write down the fastest contact channel at signup, and check whether phone support needs a paid plan.
Keep a second way to take payments ready on busy days. Your support ticket won't be answered faster because the line is out the door.
- Backup
- Second reader or Tap to Pay

Credit card readers · FAQ
What is the cheapest credit card reader for a small business?
On hardware, the PayPal POS reader at $29 for your first one, then Stripe's M2 at $59. On fees, it depends on your volume. At $3,000 a month in card sales, flat rates run from $79.50 (PayPal POS) to $96 (Square) a month by our math. Past roughly $10,000 a month, Helcim's interchange-plus pricing usually wins, because its markup is only 0.40% + 8¢ on top of what the card networks charge.
Is a flat rate or interchange-plus pricing better?
Flat rate is better when you're small, interchange-plus when you're not. A flat rate (2.6% + 15¢ at Square) is easy to read and the same on every card. Interchange-plus passes through the network's cost and adds a fixed markup, so debit cards get much cheaper and rewards cards cost more. If most of your customers pay with debit and you process more than a few thousand dollars a month, ask Helcim for a statement estimate on your real card mix.
Can I take card payments on my phone without a reader?
Yes. Tap to Pay on iPhone and Android turns your phone into a contactless reader. Stripe charges an extra 10¢ per payment for it, about $12 a month on 120 sales. It's great for a pop-up or as a backup, but it drains the battery and can't read a chip card inserted with a PIN, so most shops still keep a real reader on the counter.
Why do card processors freeze funds?
Because they carry the risk if a sale turns into a chargeback. A sudden spike in volume, an unusually large ticket or a business type they didn't expect can trigger a review, and your payouts wait until it's done. To avoid it, describe your business precisely at signup, warn support before a big event, and keep your processing steady. Flat-rate aggregators like Square and PayPal are the ones merchants complain about most.
Do I need a contract for a card reader?
No, not with the readers in this ranking. Square, Stripe, PayPal POS and Helcim show no contract on their pricing pages, and Helcim states there's no cancellation fee. Long contracts usually come from resellers and banks who bundle a terminal lease. If someone offers you a free terminal with a three- or four-year agreement, ask for the early termination fee in writing before you sign.
How fast do I get the money from card sales?
PayPal POS pays into your PayPal balance, then you move the money to your bank. Square and Stripe pay to your bank account, but payout timing isn't shown on the pricing pages we read; check it in your account settings before you sign up. If your cash flow is tight, check payout timing before you compare rates.
Do card readers accept Apple Pay and Google Pay?
Yes. Every reader in this ranking takes contactless payments, so Apple Pay, Google Pay and tap-to-pay cards all work. The fee is the same as a tapped card on flat-rate plans. On interchange-plus pricing, a mobile wallet payment is billed at the rate of the card behind it.
Should I pass card fees on to customers?
Sometimes, but check the rules first. Surcharge rules depend on your state and on the card networks, and they treat credit and debit cards differently. A cleaner option is often a small discount for cash. Before adding a fee line to your receipts, read your state's rules and ask your processor how its surcharge tool works, if it has one.
