The Card Not Authorized error could be due to a card being flagged by the bank for unusual activity. To troubleshoot:
If a second or third card fails the same way
Adding another card inside the same checkout often fails for a reason that has nothing to do with the new card. Once a payment attempt has failed, the payment method can stay attached to that attempt, so every card entered afterwards returns the same error. Try these steps in order:
If every card is declined, the problem is not with your cards. See The Card Works in Person but Not Online below.
The card works in person but not online
If your card works when you tap or insert it at the restaurant but is declined for a phone, online, catering, or manually keyed order - and your card issuer has confirmed there is nothing wrong with the card - the decline is almost certainly a setting on the restaurant's Toast account, not a problem with your card. The most common cause is that the restaurant's account is not set up to accept card-not-present transactions, meaning payments where the card is not physically presented. When that is the cause, chip and tap payments succeed and every keyed, phone, or remote payment fails, no matter whose card it is.
A cardholder cannot fix this, and no additional card will work. Contact the restaurant and tell them: the card works in person, the card issuer has confirmed there is no block on the card, and every card is being declined for remote payment. That is the fastest route to a real fix.
For restaurants: if keyed, phone, online, or catering payments are declining while chip and tap payments succeed, do not troubleshoot the guest's card. Contact Toast Customer Care to confirm that card-not-present transactions are enabled on your account and to check any transaction or daily sales limits.
