Best Credit Card Readers AI pick
Chosen by an AI model from its trained knowledge, with its reasoning.
AI pick (line): Square Square Reader (2nd generation)
It is a small Bluetooth reader that takes chip and tap payments, and it works with a free app and a merchant account you can open without a contract, so it suits most small sellers.
Not for: Businesses already on another processor, those needing magstripe swipe on the same device, or anyone who wants a standalone terminal that doesn't depend on a phone.

Square Square Terminal (line)
An all-in-one handheld with a built-in receipt printer that runs on its own battery and Wi-Fi.

For fixed countertop checkout
Square Square Register (line)
A dedicated two-screen counter POS with a customer-facing display and no tablet required.
Not for: Mobile or market sellers.
For custom software on Stripe
Stripe Stripe Reader M2 (line)
A Bluetooth reader built for apps that integrate Stripe Terminal.
Not for: Anyone without a developer or a Stripe-integrated app.
What the AI looks for in Credit Card Readers
- Processor lock-in
- The reader works only with its own provider's merchant account, so pick the processor first and the hardware second. A reader bought for the wrong processor is useless.
- Payment types
- It must take EMV chip and NFC contactless payments, including mobile wallets. Magstripe-only readers shift fraud liability onto the merchant and are effectively obsolete.
- Device compatibility
- Check the supported iOS and Android versions, and the connection type (Bluetooth, USB or Lightning). Older audio-jack or Lightning readers do not work with current phones.
- Offline payments
- Look for an offline mode that stores payments and processes them once you reconnect. Markets and events often have poor signal.
- PIN entry security
- Readers that accept PIN entry should be PCI PTS approved. This certification is required for secure PIN debit and for PIN-preferring regions.
Brands that matter
- Square: The broadest lineup for small sellers, with no contract and its own software.
- Clover: Sold through banks and processors, and hardware is often tied to a specific merchant account.
- SumUp: Simple readers for low-volume sellers in many countries.
- Stripe: Readers for businesses whose software integrates Stripe.
- Shopify: The tap and chip reader only makes sense if you sell through Shopify POS.
What to avoid
- Used or refurbished terminals that are still locked to someone else's merchant account
- Magstripe-only or headphone-jack readers
- Unbranded readers that don't name a supported processor
Questions
Do I need a reader at all if my phone supports tap to pay?
Not always. Tap to Pay on iPhone or Android takes contactless payments without hardware, but you still need a reader to accept inserted chip cards.
Can I use a Square reader with PayPal or Stripe?
No. Readers only work with their own provider's account.
