However, certain banks, like HDFC, do not stop at mobile alerts. In additions to the alerts, the bank also provides an extra security layer for all credit and debit card customers. Through this facility, the cardholder can create his own additional password, which provides an additional security layer for all On-line transactions, said HDFC Bank credit card marketing head Parag Rao.

If you have just received a new credit card from the bank, but discover that it already has a charge attached on it, don’t be surprised. These days credit fraud happens even before a new card has been received from the bank. Credit card number generators are freely available online (on sites like http://www.brothersoft.com) which claim to generate card numbers of various companies starting from ‘5’ (Master Card) or ‘4’ (Visa) or other digits. It also generates 13, 16, 18 or 19 digit card numbers. These generators use the same algorithms like `Luhn formula’ used by government agencies and banks to generate numbers.

“In one case, a hacker managed to crack the algorithm of a bank’s credit card generator and sold hundreds of numbers online. So even before the fresh card came into customer’s hands, they already had a charge on them. In another case, a credit card hacker set up a site and started using stolen card numbers to provide downloadable images and managed to siphon off about $2 million,” adds Mr Khare.

However, the biggest wrath of the credit card fraud can be felt in the E-commerce portals, which have also become like trading havens for hackers. This is how it works: A hacker enters the stolen card number and CVV (card verification value) number, as mentioned on the reverse of the card, into an e-commerce site and buys a product. The payment is made but the buyer doesn’t take the delivery immediately. He gives the delivery date – of generally a week to 10 days. During this time, the hacker posts his costly buys (from the stolen card) on the portal for sale obviously for an even lower price. As the hacker gets a customer for his product, offered at a jaw dropping price, he gives the customer’s address as the delivery address, on the same or other portal.
