Overview
There are several reasons why your card payment might be blocked and show the "Your card does not support this type of purchase" error. These are the most common reasons:
Is it a debit card? Some debit cards require a PIN to be entered. If you are trying to use one of these cards, you will need to use another card to make the payment.
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 the business is located, this could be the problem. In this case, you should contact your bank to see if you 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.
You will need to contact your credit card issuer or bank and they can give you more details as to why the payment attempt was blocked and see if they can allow the authorization. Your other option is to try a different payment method.
