According to Stripe, our payment gateway, this message likely means:
Your debit card requires a PIN to be entered. If you are trying to use one of these cards, you’ll need to use another card to make the purchase.
Your card has restrictions on cross-border usage. If the card was issued in a country (the ‘origin’ field when you view the details of the payment) other than where your business is located, this might be the problem. In this case, please contact your bank to see if they have this restriction.
Your card (often corporate cards or FSA cards) can only be used for certain business categories, like travel or healthcare.
