The onus would be on the credit card companies to collect about 10 questions and answers from a customer while registering. And when any e-commerce site asks for information about a credit card from the cc company it should also send any 3 q’s n a’s of the customer. So the customer using the e-commerce site gets these 3 q’s n only after he answers them, should he be asked to fill in the CVV details. This might limit the mis use of credit cards (online atleast)
PS: No “sucky idea” comments please !!!
