What's the best card reader for the self-employed?

Mobile hairdresser, handyman, farmers market vendor or photographer: you take payments alone, on the move, and not every day. Here's what each reader really costs you.

Short answer: SumUp is the best card reader for most self-employed people in the US. It charges 2.6% + 10¢ per in-person payment, $0 a month, with next-day payouts. PayPal POS is the cheapest per swipe at 2.29% + 9¢, with a $29 first reader, but it can hold transactions. Square costs a nickel more per sale than SumUp, yet gives you a free magstripe reader, an offline mode and the easiest path to a full point of sale. With bigger tickets or a growing volume, Helcim's interchange-plus pricing (0.40% + 8¢ markup) can cost less, depending on your customers' cards. At $1,000 a month, the gap between these options is a few dollars, so pick on where you sell and when you need the cash. We compared five readers over a full year, at $1,000 and $2,500 in monthly card sales.

Our method

How we compared and scored

A sole proprietor doesn't take payments like a store. You run a handful of sales a day, sometimes none for a week, often far from Wi-Fi. So we priced every reader at two volumes that look like a one-person business: $1,000 and $2,500 in card sales a month, with a $30 average ticket (about 33 and 83 sales). Then we added the hardware to get your first-year cost.

Rates, hardware and payout times come from each provider's official pricing page in 2026. We then read user reviews and forum threads, starting with the worst: held payouts after a big weekend, readers dead after a slow season, support you can't reach. Scores are the same as in our overall ranking. We didn't open merchant accounts: we compared what providers publish and what their users report.

Two names are missing on purpose. Clover Go and QuickBooks GoPayment come up in other rankings, but we couldn't read their current rates on an official page, and we don't publish a price we can't check.

Best for most self-employed

SumUp

4.1/5

SumUp charges 2.6% + 10¢ per in-person payment in the US, with no monthly fee and no contract. Keyed-in and online payments cost 3.5% + 15¢. At $1,000 a month in card sales, that's $29.30 in fees; at $2,500, $73.30 (our math, $30 tickets).

Against Square, the difference is the fixed fee: 10¢ instead of 15¢. It sounds tiny, but on 83 sales a month it's $4.15 back in your pocket, about $50 a year. Payouts land the next day, which matters when you buy supplies with last week's sales.

The catch is support. Reviews describe a support team that's hard to reach and accounts held during verification, sometimes for weeks. And there is no offline mode listed on its US pricing page, so check signal where you sell.

Standout features
  • 2.6% + 10¢, the lowest flat rate after PayPal
  • No monthly fee, no contract
  • Next-day payouts
+Pros
  • ✓Simple, predictable pricing
  • ✓Cheaper than Square on every sale
  • ✓Good fit for low, irregular volume
−Cons
  • ✗Support hard to reach in reviews
  • ✗Funds held during account checks
  • ✗Offline mode not listed on its US pricing page
Verdict

The best default for a one-person business. Choose Square instead if you want offline mode or plan to grow into a full POS.

Easiest start, offline mode

Square

4.0/5

Square charges 2.6% + 15¢ per in-person payment on its Free plan, $0 a month. The magstripe reader is free, the contactless and chip reader costs $59, and the Square Terminal $299. At $1,000 a month, you pay $30.95 in fees; at $2,500, $77.45 (our math).

For a solo seller, two things set Square apart. Its offline mode lets you keep taking cards when the market's signal dies, and the free point-of-sale app grows with you if you add products, inventory or a second seller. Paid plans (Plus and Premium) cut the rate a bit, but at your volume the Free plan is the right one.

The catch: like every flat-rate processor, Square can hold payouts it flags as risky, especially on a new account or after a sudden spike. And that fixed 15¢ hurts small tickets.

Standout features
  • Offline mode
  • Free magstripe reader
  • Free POS app that grows with you
+Pros
  • ✓Easiest start, nothing to buy
  • ✓Keeps selling with no signal
  • ✓Clear upgrade path
−Cons
  • ✗15¢ fixed fee on small tickets
  • ✗Can hold payouts on new accounts
  • ✗Contactless reader costs $59
Verdict

The best pick if you sell outdoors or want to grow into a full POS. If you only take a few cards a week, SumUp is a bit cheaper.

Best on big tickets

Helcim

3.8/5

Helcim doesn't charge a flat rate. It passes through interchange (the fee card networks set) and adds a markup of 0.40% + 8¢ per in-person sale below $50,000 a month. No monthly fee, no contract. On $1,000 a month, the markup is $6.64; on $2,500, $16.64 (our math), plus interchange, which depends on your customers' cards.

For a contractor billing $800 jobs, that model wins: on large tickets, the gap with a 2.6% flat rate is real money. On a debit-heavy mix, it wins even more. On premium rewards cards, the edge shrinks.

The catch for a beginner: the Card Reader costs $199, and you can't know your exact total before your first statements. If you sell $1,000 a month, the reader alone eats most of the first year's savings.

Standout features
  • Interchange + 0.40% + 8¢
  • No monthly fee, no contract
  • Best on large tickets
+Pros
  • ✓Low markup on every sale
  • ✓Transparent pricing model
  • ✓Debit cards cost much less
−Cons
  • ✗$199 reader
  • ✗No single rate to compare up front
  • ✗Statements harder to read
Verdict

Worth it once your card volume or ticket size grows. Too much hardware cost for a side business.

You already have custom software

Stripe Terminal

3.5/5

Stripe Terminal charges 2.7% + 5¢ per in-person payment, plus 10¢ for Tap to Pay on your phone. The M2 reader costs $59. At $1,000 a month that's $28.65; at $2,500, $71.65 (our math).

The rate is fine. The problem is setup: Stripe Terminal is a toolkit, not an app you download. It needs software built around it. If your booking tool or website already uses Stripe and supports Terminal, it's a clean way to keep everything in one place.

If you're a solo seller without a developer, skip it. SumUp, Square or PayPal POS work out of the box.

Standout features
  • 2.7% + 5¢
  • M2 reader at $59
  • One dashboard with your online sales
+Pros
  • ✓Low fixed fee per sale
  • ✓Unified with Stripe online payments
−Cons
  • ✗Needs developer integration
  • ✗Tap to Pay adds 10¢
  • ✗No ready-made app for solo sellers
Verdict

Only if your software already speaks Stripe. Otherwise, pick a reader you can use today.

Cheapest per swipe

PayPal POS

3.4/5

PayPal POS (formerly Zettle) charges 2.29% + 9¢ per in-person payment, with no monthly fee. Your first reader costs $29, then $79; the Terminal is $199. At $1,000 a month, you pay $25.87 in fees; at $2,500, $64.72 (our math). That's the lowest flat rate in this ranking.

Over a first year at $1,000 a month, reader included, PayPal POS comes to about $339, against $371 for Square with its free magstripe reader. If you already sell online through PayPal, both channels land in the same balance.

Why it isn't higher: PayPal says transactions may be held, and reviews describe readers failing after a few months, or after sitting unused for a season, with support bounced back to PayPal. Its reliability score is the lowest here.

Standout features
  • 2.29% + 9¢
  • $29 first reader
  • Online and in-person in one balance
+Pros
  • ✓Lowest flat rate
  • ✓Cheap entry hardware
  • ✓No monthly fee
−Cons
  • ✗Transactions may be held
  • ✗Readers failing in reviews
  • ✗Support routed through PayPal
Verdict

The cheapest per sale. Keep a backup way to get paid, because a dead reader on market day costs more than the fee savings.

Your cost, your work

What your reader really costs in year one

At low volume, the reader price matters as much as the rate. Here are monthly fees at $1,000 and $2,500 in card sales, $30 average ticket, US cards (our math from official rates).

  • PayPal POS at 2.29% + 9¢: $25.87 and $64.72.
  • Stripe Terminal at 2.7% + 5¢: $28.65 and $71.65.
  • SumUp at 2.6% + 10¢: $29.30 and $73.30.
  • Square at 2.6% + 15¢: $30.95 and $77.45.
  • Helcim: $6.64 and $16.64 in markup, plus interchange.

Over twelve months at $1,000 a month, hardware included: PayPal POS about $339, Square $371 with the free magstripe reader or $430 with the $59 contactless one, Stripe $403 with the M2. The spread is under $100 a year. What really decides it is signal where you sell and how fast you need the cash.

You work at clients' homes

Hair, massage, tutoring, repairs: you nearly always have a phone signal. A Bluetooth reader from SumUp or PayPal is enough. Start with Tap to Pay on your phone if you take only a few cards a week.

You sell at markets and fairs

Signal collapses when the crowd arrives. Take Square for its offline mode, run a $1 test sale before opening, and ask the organizer for Wi-Fi.

You bill jobs and deposits

Contractor, photographer, trainer: fewer, bigger payments. Watch for holds on new accounts. Send ID and business documents at signup, and once you pass a few thousand a month, price Helcim.
  • Price your fees over twelve months, reader included.
  • Check whether the reader works offline.
  • Check when payouts land and in which account.
  • Send all verification documents at signup.
  • Tell your provider before a big event.
  • Keep a backup: Tap to Pay on your phone.
What other rankings skip

Held funds, dead signal, sleeping readers: the solo seller's traps

Most rankings compare reader prices. Self-employed sellers in forums and reviews talk about something else: the payout that didn't come after a big weekend, the reader that won't connect in a crowded market, the device that won't wake up in spring. Six points from those threads.

01

Payouts held on a new account or after a spike

Cash flow

A brand-new account, a sale far larger than usual, a deposit taken before the job: those are the triggers flat-rate processors use to hold money. PayPal states transactions may be held; reviews of SumUp describe balances frozen for weeks during checks.

Describe your business precisely at signup ("wedding photographer", not "services"), upload ID and business documents right away, and warn support before a large job or event. If a payment is held, ask for the reason in writing.

Habit
Warn support before big events
02

Bluetooth, standalone or phone only

Hardware

Bluetooth readers are cheap but live on your phone's battery and signal. Standalone terminals (Square Terminal, PayPal Terminal) cost $199 to $299 and work on their own. Tap to Pay needs no hardware at all but only takes contactless.

Simple rule: fewer than five sales a day with signal, your phone or a Bluetooth reader is enough. Outdoors or nonstop, go standalone.

Cheapest start
Square magstripe, free
03

The network dies when the crowd shows up

Events

Festivals and holiday markets put thousands of phones on one cell tower. One seller describes a whole wine festival without card payments because the network was saturated.

Arrive early and run a $1 test sale. Ask for the organizer's Wi-Fi. Use Square's offline mode. And post a sign saying you also take cash.

Before opening
Run a $1 test
04

The reader that sleeps all winter

Hardware

Reviews describe readers stored for months that no longer work, or that fail right after warranty. A drained battery or a missed firmware update can cost you opening day.

Charge it once a month, turn it on so it updates, and run a test sale a week before reopening.

Upkeep
One charge a month
05

The fixed fee on small tickets

Math

On a $5 sale, Square's 15¢ fixed fee adds 3 points to the rate; SumUp's 10¢ adds 2, PayPal's 9¢ adds 1.8. If you sell coffee, candles or produce, the fixed fee matters more than the percentage.

If your average ticket is under $10, compare total fees on your real basket, not the headline rate.

On a $5 sale
15¢ = 3% extra
06

When interchange-plus beats a flat rate

Math

Flat rates like 2.6% are simple. Interchange-plus (Helcim) passes through the card network fee and adds a small markup. At low volume, the $199 reader eats the savings. With large tickets or several thousand a month, the markup of 0.40% + 8¢ leaves far more in your pocket.

Ask Helcim to estimate your costs from a real month of card sales before switching.

FAQ · 6 questions

Card reader for self-employed · FAQ

  • What's the cheapest card reader for a small business?

    Square's magstripe reader is free, and Tap to Pay on your phone needs no hardware. For chip and contactless, PayPal's first reader costs $29. But at $1,000 a month, the rate matters more than the device: PayPal POS's 2.29% + 9¢ saves about $5 a month over Square.

  • Which reader has the lowest fees at $2,500 a month?

    Among flat rates, PayPal POS: $64.72 a month, against $73.30 for SumUp and $77.45 for Square (our math, $30 tickets). Helcim's markup is only $16.64 at that volume, but interchange comes on top, so ask for an estimate on your real card mix before you switch.

  • Can I take card payments with just my phone?

    Yes, with Tap to Pay: your phone reads contactless cards and wallets. Stripe charges 10¢ extra per Tap to Pay sale. It's a great backup or a way to start, but it drains your battery and only takes contactless.

  • How do I take cards with no signal?

    Use a reader with an offline mode, like Square's: it stores the payment and processes it when the connection comes back. Run a test sale before opening, and keep cash as a fallback.

  • Why is my card processor holding my money?

    Usually a risk check: new account, unusual sale, or a deposit before the job is done. Ask for the reason in writing, send your documents right away, and move your balance to your bank regularly.

  • Is a monthly plan ever worth it for a freelancer?

    Rarely below a few thousand a month. Square's paid plans and interchange-plus models pay off with volume. At $1,000 a month, stay on a free plan with no contract.
