When the iPhone was first introduced, few thought it would stimulate growth for small businesses, but that is exactly what happened. Now, even food trucks and cash-strapped merchants can afford to accept credit cards on iPhone.

To take credit card payments on iPhone, you need:

  1. Apple device (iPhone or iPad) connected to WiFi or cell phone coverage
  2. Credit card reader by a mobile payment provider
  3. Credit card processing app downloaded on the mobile device

Choosing the right service is essential, as monthly fees and transaction charges can sneak up on you. We’ve pinpointed the six best credit card apps with the most bang for the buck.

Square Reader and iPhone app

Pocketable Square Reader works with the best free POS app available in the US.

Apart from a beautiful product library with detailed product information, you can add several staff accounts (advanced permissions cost extra), add discounts, track inventory and much more with the free software. Square can be expanded with more advanced POS systems for retail and restaurants, booking systems, marketing, customer loyalty tools, ecommerce and many partner apps.

It’s recommended you use the most recent app for iOS for the best app performance. The most frequent complaint about Square has been lackluster customer service, leading people to look for alternatives to Square.

SumUp merchants can also get a free virtual terminal for remote payments, usable in the app or web browser, for 3.25% + 15¢ per transaction.

PayPal Zettle – payouts in online account

  • Ergonomic card reader with physical PIN pad

  • User-friendly, free PayPal Zettle app

Pricing

The PayPal Zettle app allows merchants to accept payments from most credit cards for 2.29% + 9¢ per swipe and 3.49% + 9¢ per manually entered card. For foreign cards, there is a 1.5% additional cross-border fee plus a 3% currency conversion fee if relevant.

PayPal’s credit card reader works with a user-friendly iOS app.

All transactions are automatically deposited in your online PayPal account and have to be transferred manually to your bank account. Alternatively, you can get the PayPal Business Debit Mastercard to spend funds directly from the e-money account.

Besides the ability to record cash sales in the app, PayPal Zettle merchants can accept gift cards, QR code payments and send invoices and payment links to customers. There is also a product library with images and stock levels, sales reports and discount options.

The main advantage is the ability to integrate the account with the online payment features available on the PayPal Business platform.

QuickBooks GoPayment – good accounting integration

  • Small, round card reader for contactless and EMV card payments

  • Basic, free payment app

  • Connects with QuickBooks accounting software

  • Payouts in bank account within 2-3 business days

Pricing
QuickBooks subscription required
QuickBooks card reader: $49
QB Online users: Pay as you go, but $9.95/mo PCI compliance may apply
Tap/dip rate: 2.5%
Keyed rate: 3.5%

QuickBooks GoPayment (previously Intuit GoPayment) was among the first players targeting small businesses with the option to accept payments any time, anywhere.

The credit card payment app can be used without a monthly subscription, as long as you’re subscribed to a QuickBooks Online or Desktop accounting package.

QuickBooks Online subscribers can use the GoPayment app on a pay-as-you-go basis, in which case card reader payments cost 2.5% and keyed transactions cost 3.5%.

With a QuickBooks Desktop plan, you can opt for a $20 monthly subscription, reducing contactless and EMV transaction fees to 1.6% + 30¢, whereas keyed transactions are 3.3% + 30¢ each.

GoPayment’s card reader accepts EMV (chip) and NFC (contactless) cards, but not swipe.

PCI compliance costs $9.95 per month on any pay-as-you-go plan, but is included on the monthly plan for Desktop subscribers.

POS features include personalized digital receipts and up to 50 user accounts, which means all your employees can accept payments on the go.

Since Intuit is the maker of QuickBooks accounting software for small businesses, one of the notable features is the automatic synchronization with QuickBooks, although this requires an additional subscription.

Clover Go – comes with merchant account

  • Compact card reader for tap and EMV

  • The higher the monthly cost, the more iPhone app features

  • With merchant account

  • Payouts in bank account (varying settlement times)

Pricing
$0 or $14.95 monthly fee
Clover chip & tap reader: $49
Tap/dip rate: 2.6% + 10¢
Keyed rate: 3.5% + 10¢

Clover offers a full range of point of sale (POS) products that can be adapted to most checkouts, spanning from an iPhone credit card reader (Clover Go) to full-fledged hardware and POS software. All the Clover products come with a merchant account for stable mobile credit card processing.

The fees have been simplified a little in recent years. Before, you had to get a contract through partner banks like Bank of America. Now, you can subscribe on the Clover website for no monthly cost (Payments plan) for payments only, or $14.95 a month for basic inventory features (Essentials plan).

The latest Clover Go card reader is very small and accepts tap and chip payments.

Essentials provides handy features like employee management (e.g. payroll, work shifts, permissions), refunds and dashboard reports.

The card reader costs $49 regardless of the plan. All plans charge 2.6% + 10¢ per contactless or chip card payment and 3.5% + 10¢ per keyed card payment.

Payanywhere – competitive for low-volume merchants

  • Small, simple card reader

  • Decent, free payment app for iPhone

  • For monthly turnover of less that $10k – if exceeding it, you may start to pay monthly fees

  • Next-day payouts in bank account

Pricing
Pay as you go, but $3.99 monthly fee after 12 months of inactivity
Swipe, chip & tap reader: $59.95
Swipe, EMV & tap fee: 2.69%
Keyed-in cards: 3.49% + 19¢

Payanywhere’s pay-as-you-go app for businesses doesn’t cost anything monthly – just need the matching 3-in-1 card reader that costs $59.95 upfront. It accepts swipe, dip and tap payments for 2.69%, while keyed transactions incur a fee of 3.49% + 19¢.

If you have not had a single transaction in the last 12 months, you pay a monthly inactivity fee of $3.99. This fee stops applying as soon as you take the first payment again.

Payanywhere card reader connects wirelessly to your cell phone via Bluetooth.

The pay-as-you-go plan is only suitable for businesses with a monthly card turnover of less than $10k. If you reach this limit, Payanywhere has been known to automatically roll you into a different merchant contract with new fees and terms.

Transactions processed before 5pm are deposited in to your bank account the next business day for free; those processed after 5pm may reach your bank account the weekday after. There’s also a same-day transfer option for eligible users.

The Payanywhere app has some great reporting functions where you can customize analytics to focus on sales, payment methods and employee performance. You also get open tickets and tabs, invoicing, inventory features and more. Overall, Payanywhere is good value for money.

Summary: which to choose?

Small American businesses are spoilt for choice when it comes to credit card readers. Although Square still offers the most compelling product suite, SumUp is a close second where a low price and lack of commitment are concerned. PayPal Zettle offers quality card readers too, but with more complicated fees and no automatic bank account payouts.

QuickBooks is only worth considering if you’re using their accounting system already, since a subscription to their software is required. Its iPhone app is basic, so it’s more a solution to occasional transactions in person than a full-fledged point of sale terminal.

Clover has long been a popular choice for small businesses who want a whole infrastructure of sleek-looking POS terminals, and its iOS-based card reader is similarly attractive on its own. It comes with a merchant account promising more payout stability, but Clover is also known for hidden costs.

Our last option, Payanywhere, looks modern and feature-rich on the website, but has a monthly fee kicking in if you don’t use the iPhone reader for a year. This basically means you agreed to a contract with cancellation requirements – a now old-fashioned requirement in the world of pay-as-you-go card readers.
