Praveen, I am not sure for all the banks, but for the few private banks I have been bankign with, there is a clause which states that the debit card are protected against fraudelent POS transactions, ie.e transactions done by swiping the card. The transactions done 30-45 days prior to the loss of card are protected. So my take is that debit cards are more secure than credit card...at least on this count.
