Sagar It all depends on your cc bills and the cards you hold
-->in brief is spending is more than 1l/month from cc
then get 1 card which maximise your benifit
-->if more than 2L get 2 cards and so on.
-->if its below 25k/month then go for EDC
It doesnt matter you will go with hdfc/idfc/rbl etc etc in the end you will be getting 1% or 5% depending the card you choose .
in my case all the accounts are not my salary one so i just move into them to pay cc bill.
And for [Login to see the link] rewards are less than 1% if you have a basic account there.
