We have recently upgraded our payment processing provider. As part of this you may need to re-enter your card information against your account.
Our new payment gateway uses the latest in 3D secure technology to help prevent fraudulent transactions. As part of this you may be asked for some additional information, or your bank may send you a one-time code via your banking app or SMS enter to approve and finalise the transaction. Your transactions may also appear slightly different on your bank statement.
