Yesterday i was going thru ICICI online banking and found something new called Virtual Credit card (i dont know when they introduced). It is linked to actual credit card and here we can set whatever limit we want, but less than actual card's limit. It means for online shopping and usage we can use this virtual card and keep the limit very low. So that even if hacker gets hold of your card he cant enjoy much coz your card limit may be very less.
hmm dont you think it is a cool feature for safe online shopping!
btw when I was googling more about this I found another thing Kotak net card, which is even more better. In this case it is linked to debit card and with very less activation period and credit limit. hmm lot new stuff to make online shopping safe.
