There are a number of reasons why a transaction might be declined.

Here are the list of the most common ones:

• You’ve not activated your card

• Your PIN is blocked. This happens when you enter the PIN incorrectly 3 times. Find out how to unblock in the app with this FAQ

• The transaction will take you over your credit limit

• The transaction cost will take you into your Credit Cushion amount. You can edit your Credit Cushion in the Manage section of the app

• If it’s your first in-person spend, you’ll need to use Chip and PIN to show it’s you – afterwards, you’ll be able to use contactless up to £100

• You've frozen your card. If this is the case, the card will appear frozen in the app, and you can unfreeze it from there

• You’ve blocked cash withdrawals in the manage section

• We think that the transaction might be fraudulent. To protect our customers from transaction fraud, we may decline transactions that look suspicious, and block the card from further spending

• There may have been a technical issue on the merchant’s network

If your transaction was online:

• The 3D secure code you entered may be incorrect

• You may have entered the wrong card details, such as your PIN or expiry date
