Transaction Error: Unrecognized card type. Please try again with a Mastercard, Verve or VISA

What does 'Unrecognized card type. Please try again with a Mastercard, Verve or VISA' mean?

This means that the customer used a card that isn't acceptable on Paystack.

Currently, Paystack only supports transactions attempted with Verve, Mastercard and Visa cards. We also support American Express cards for businesses in South Africa.

What can I do about it?

The customer needs to retry the transaction with a Mastercard, Verve card or VISA card. Alternatively, the customer can try another payment channel on the checkout.
