Details you will need
Have the card in your hand first. The lookup asks for three things, all printed on the card itself:
- The card number running across the front.
- The expiry date, shown as a month and a year.
- The security code, typically on the back near the signature panel.
Where a scratch coating hides part of the code, wipe it off lightly with a coin so you do not damage the numbers.

If the amount looks off
First, read through each digit you entered again, as a single wrong number is the usual cause. Payments that are still processing can also lower the amount you see for a while. If the figure is still odd after a day or two, phone the issuer using the number on the back of the card.
