when you are shopping online and are asked for your credit card number, which one do you give - is it the longest one in the centre of the card or the 'card number' at the bottom of the card? thanks
I assume you are referring to a debit card as my credit cards only have the sixteen digit number which is the one you should give. The may also ask for the validation code which is the last three numbers from the signature strip. On a debit card the card number is the number at the bottom as the other number is your bank code and account number.
