In any month, if you transact in 3 or more different categories, then for the top 2 Categories your rewards points will be multiplied by 5.
For example: If you transact for ₹500 for Ordering Packet Food Items (Grocery), ₹500 for
Booking Movie Tickets,(Entertainment), and ₹100 for Train Tickets (Travel) Booking in any month, then, for your Grocery and Entertainment category, Rewards Points will be 5x the usual 0.2% rate. So, you will be getting 1% rewards points for those two categories. That is 5 Reward Points each for Grocery and Entertainment, and 0.2 Reward Points for Travel.
