Card Readers for Small Business: 2026 Fees Compared
Card readers for small business compared: Square, Stripe, SumUp, Clover and tap to pay on phones, with 2026 hardware prices, fees and a cost example.
Quick answer: The best card readers for small business in 2026 are low-cost mobile readers from Square ($59, 2.6% + 15 cents per in-person payment) and Stripe (Reader M2 $59, 2.7% + 5 cents), plus free tap to pay on a phone. Choose by processing rate on your volume, the software you need and whether you need chip, tap or both.
A card reader lets you take in-person payments at a counter, a market stall or a customer's home. The hardware is cheap now; the ongoing fees and software matter more. This guide compares the main options, explains every fee involved, shows a cost example at different monthly volumes and lists mistakes to avoid. Prices and rates are as of October 2026 from each provider's US pricing page; check the current page before buying.
What is a card reader and how does it work?
A card reader is a device that accepts chip (EMV), contactless (NFC) and sometimes swiped card payments, plus Apple Pay and Google Pay. Mobile readers connect by Bluetooth to a phone or tablet running the provider's app. Countertop terminals and handheld smart terminals run their own software and connect by Wi-Fi, Ethernet or cellular. The reader encrypts card data and sends it to the processor, which authorizes the payment with the card network and issuing bank, then pays out to your bank account, usually within one or two business days.

How much do card readers cost to run?
Total cost has four parts:
- Hardware: one-time, from $0 (phone) to a few hundred dollars for a smart terminal.
- Processing rate: a percentage plus a fixed fee per transaction. This is the big one.
- Software: free basic POS apps; paid plans for inventory, staff, restaurants or appointments.
- Extras: cellular data, chargeback fees, instant payout fees, and on traditional accounts, PCI and statement fees.
Flat-rate pricing (Square, Stripe, SumUp) is simple and predictable. Interchange-plus pricing from merchant accounts can be cheaper at higher volume but harder to read. See credit card processing fees and merchant account vs payment processor for how those structures compare.
Worked example: what a card reader costs per month
A mobile dog groomer takes 120 card payments a month at an average of $75, so $9,000 in card sales. Using the published US rates above:
| Cost item | Square Reader | Stripe Reader M2 | Stripe Tap to Pay |
|---|---|---|---|
| Percentage fee | 2.6% x $9,000 = $234.00 | 2.7% x $9,000 = $243.00 | 2.7% x $9,000 = $243.00 |
| Fixed fees | 120 x $0.15 = $18.00 | 120 x $0.05 = $6.00 | 120 x ($0.05 + $0.10) = $18.00 |
| Monthly processing | $252.00 | $249.00 | $261.00 |
| Effective rate | 2.80% | 2.77% | 2.90% |
| Hardware (one-time) | $59 | $59 | $0 |
At this volume the rates are within a few dollars of each other, so software, payouts and ease of use matter more than the rate. The fixed fee matters more with small tickets: at a $10 average sale, Square's 15 cents is 1.5% on top of 2.6%, while Stripe's 5 cents is 0.5%. A coffee cart and a contractor should not pick the same reader for the same reasons.
How to choose a card reader: step by step
- Estimate volume and ticket size. Monthly card sales and average sale drive which pricing is cheapest.
- List where you sell. Counter, outdoors, customer homes or online too. Outdoor sellers need battery life and maybe cellular.
- Decide on software needs. Inventory, tips, appointments, table service, invoices and staff permissions.
- Check payout speed. Standard next-business-day payouts are usually free; instant payouts cost extra.
- Read contract terms. Avoid long contracts, leases on hardware and early termination fees unless the savings are clear.
- Test with real customers. Start with a low-cost reader or tap to pay before buying a full terminal.
- Connect it to your books. Make sure deposits, fees and refunds are easy to reconcile.
What types of card readers are there?
Mobile readers
Small Bluetooth readers that pair with a phone or tablet. They accept chip and tap payments and cost around $50 to $70. Best for low to moderate volume, markets, pop-ups and service calls. Battery life and Bluetooth pairing are the main practical issues.
Tap to pay on a phone
No hardware at all: the phone's NFC chip accepts contactless cards and wallets. Ideal for occasional sales and mobile trades. It cannot take chip-inserted payments, so keep a backup option for older cards.
Smart handheld terminals
All-in-one devices with a screen, card reader and sometimes a receipt printer, such as Square Terminal or Stripe's S700. They run the POS app on the device, which suits restaurants, salons and retail counters. Expect a few hundred dollars per device.
Countertop POS systems
Full registers with a customer-facing display, cash drawer and printer. Clover and Square Register are examples. They cost the most and usually come with software subscriptions, but they handle inventory, staff, tips and reporting for busy shops.
Traditional merchant terminals
Standalone terminals supplied by banks and independent sales organizations, often with a merchant account and sometimes a lease. They can suit high-volume businesses that negotiate interchange-plus pricing, but read the contract carefully.
What fees show up on a card reader statement?
Flat-rate providers show one fee per payment, but your monthly statement may also include refunds (the processing fee is often not returned), chargeback fees, instant payout fees and software subscriptions. Traditional merchant statements can include interchange, assessments, a processor markup, PCI compliance fees, statement fees and monthly minimums. Divide total fees by total card sales to get your effective rate, and compare that number each month. If your effective rate creeps above 3.5% on a flat-rate plan, look for add-ons you are paying for and do not need.
Card reader vs invoicing: when to use each
Readers are for payments while the customer is in front of you. For work billed after the job, a deposit, or business clients who pay on terms, send an invoice with a payment link or bank details instead. Many service businesses use both: tap or chip for on-the-spot payments, and invoices for larger jobs. You can create an invoice in minutes with our free invoice generator and add a payment link; see how to add a payment link to an invoice. For phone-only setups, read our Tap to Pay on iPhone guide.
Common mistakes when buying a card reader
- Comparing only the percentage. The fixed fee and add-ons change the effective rate, especially on small sales.
- Signing a hardware lease. Leased terminals can cost far more over a multi-year term than buying.
- Ignoring chargebacks. Know the dispute fee and process; read how to handle chargebacks.
- Surcharging incorrectly. Surcharges are banned on debit cards and limited by state and network rules; see credit card surcharge rules.
- Skipping PCI basics. Encryption helps, but you still need secure devices and staff practices; see PCI compliance for small business.
- Not giving receipts. Customers and your bookkeeping both need them; a payment receipt template helps for non-POS payments.

Frequently asked questions
What is the cheapest card reader for a small business?
The cheapest hardware is no hardware: tap to pay on a compatible iPhone or Android phone through Square, Stripe or similar apps costs nothing upfront. Among physical readers, Square's contactless and chip reader and Stripe's Reader M2 both list at $59 as of October 2026. The bigger long-term cost is the processing rate, so compare fees on your expected monthly volume.
Do card readers have monthly fees?
Many mobile readers have no monthly fee: you pay the hardware and a per-transaction rate. Monthly fees appear with point-of-sale software plans, cellular connectivity (Stripe lists $10 per reader per month for cellular), and traditional merchant accounts. Read the pricing page for software subscriptions, PCI fees and early termination clauses before signing anything with a long contract.
Can I take card payments on my phone without a reader?
Yes. Tap to Pay on iPhone and tap to pay on Android let compatible phones accept contactless cards and digital wallets through a provider's app. It works well for mobile service businesses. You cannot accept chip insertion or swipes this way, so customers with non-contactless cards need another option, such as a payment link or a physical reader.
Are card reader fees tax deductible?
Yes. For a business, both the hardware cost and processing fees are ordinary business expenses. Processing fees are usually recorded as merchant or bank fees. The reader itself is equipment, and small items are commonly expensed in the year purchased under the de minimis safe harbor if you have elected it. Keep the receipt and monthly processor statements.
Should I pass card fees to customers?
You can in many states, either as a surcharge on credit cards or as a cash discount, but rules differ by state and by card network, and debit cards cannot be surcharged. Surcharges must be disclosed and capped. Many small businesses simply build card costs into prices. See our guide to credit card surcharge rules before adding any fee to receipts or invoices.
Which card reader works without internet?
Most readers need a connection to authorize payments, either through the phone's data or Wi-Fi. Some systems offer an offline mode that stores payments and processes them later, but you carry the risk if a card declines once you reconnect. Readers with built-in cellular connectivity are an alternative for markets and job sites with weak Wi-Fi.
Do I need a merchant account to use a card reader?
Not with payment facilitators like Square, Stripe or SumUp, which onboard you under their own master account so you can start within a day or two. Traditional merchant accounts from banks or ISOs require an application and underwriting but can offer lower rates at higher volumes. Our merchant account vs payment processor guide explains when switching makes sense.
Is a card reader PCI compliant?
Modern readers from major providers encrypt card data at the point of entry, which greatly reduces your PCI DSS scope, but you are still responsible for basic compliance such as protecting devices, not writing down card numbers and completing any required self-assessment. Providers explain what they cover. Read our PCI compliance guide for small businesses for the remaining steps.
