If your Business Account's balance isn’t sufficient to cover the cost of the transaction, your attempted payment will fail. Check your available balance or change your payout method to add more money.
Entering the wrong PIN will mean your payment cannot be authorised and will therefore fail. You can quickly and easily change your PIN with your SumUp profile if you’ve forgotten it.
We include transaction limits on your card to keep you secure should your card be lost or stolen.

In some circumstances, it's possible to change your SumUp Card limits by contacting our Support Team.
With SumUp, you can temporarily block your card to protect it if it has been misplaced or stolen. If you have since found your card and continued using it, it may be that the block is still in place and you need to unblock your card to continue using it.
If you believe your card has been permanently blocked, contact our Support Team for help.
SCA not enabled
Strong Customer Authentication (SCA) authenticates card-not-present transactions to prevent fraud. Once you enable SCA, you need to confirm payment in the SumUp App when making a purchase. Without this confirmation, the transaction will fail.
If, after enabling SCA, attempted purchases still fail, either contact the shop you’re buying from, use a different payment method, or try a different internet browser.
To protect you from fraudulent use of your card, both the card issuer and acquirer are able to decline a transaction if suspicious activity is detected.
