Unfortunately you don't get 0% credit cards in India - but people elsewhere can take advantage of this:
1. Apply for a 0% APR credit card that has no cash advance fee.
2. Withdraw cash from that credit card and invest it in a safe place.
3. Pay the low monthly fees on time. And pay the remainder balance a week before its due.
