What is a debit card number?

ok if it is asking for debit card number then the number which will be valid for that field should be only acceptable if your HSBC card has got master card or VISA logo on it the payment page says they accept master card, visa, amex, dinners etc. or else it wont accept the normal bank cards as it cannot be debited with out the pin.. and if it asks for the pin then plz dont give it out.

Hope this answers your question.
