Square processes all cards with the same standard rate.

Note: The following card types aren’t currently supported: Discover, JCB or UnionPay International.

Accept Prepaid Cards

The Square Point of Sale app and Square Terminal can process prepaid cards with any of the accepted logos listed above at our standard 1.75% + VAT per-transaction rate for contactless and chip and PIN payments.

Note: When manually entering a prepaid card, check that your customer has registered the card with a billing address and postcode, which can be done by contacting the card issuer. Information on how to register the card may also be available on the back of the card.

Accept International Cards

Square can process most internationally-issued cards with a Visa, MasterCard, American Express, Maestro, Visa Electron or Vpay logo.

Square Reader and Square Terminal accept chip and PIN cards and contactless cards and devices. Note: Only Square Terminal and Square Stand (1st generation) can accept international magnetic stripe card payments.

You can also use the manual entry feature to process an international card. To do so, make sure you have the card number, CVV, expiry date and the Eircode.

Keep the following in mind when processing international cards:

  • To switch between numbers and letters on your device:

    • iOS: Tap ABC or 123 at the lower left of the screen

    • Android: Tap the keyboard icon to the right of the payment card field

  • While most internationally-issued cards are accepted, processing them is subject to issuer approval. If you experience issues processing an internationally-issued card, have the cardholder contact their card issuer.

  • Cardholders may be charged for currency conversion by their card issuer as payments are processed in your country’s official currency.

  • In order to process payments, you need to be located in the country where you activated your Square account and first powered on your Square payment device.
