ive searched for previous debit card threads, and i havnt found one that answers my question.
i have a debit card, and want to verify it. its a mastercard, so it should work. i fill in everything right, but the only thing im doubtful about is teh "Security Code" part. whats that? ur social security?( i highly doubt it, but who knos?) is it located somewhere on my card? it says its 3 digits, or 4 if its "AMIX" or sumthin like that. maybe one of those numbers on the back?
thanks a bunch
