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.
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.
