"Your card does not support this type of purchase" error:
Is it a debit card? Some debit cards require a PIN to be entered. If your customer is trying to use one of these cards, they will need to use another card to make the purchase.
Does it have cross-border restrictions? Some cards have restrictions on cross-border usage. If the card was issued in a country other than where your business is located (found in the
origin field when you view the details of the payment), this could be the problem. In this case, your customer should contact their bank to see if they have this restriction, and if so, if it can be removed.
Is it an HSA or FSA card? Some cards, such as corporate cards or FSA cards, can only be used for certain business categories such as travel or healthcare. If your customer indicates that their card might only be available for certain business categories and it should work for your business, contact Stripe Support.
