I'm using some 4-5 accounts for my online transactions. So far what I feel the best is ICICI pockets account which can be upgraded to basic savings account without any limit. Also KOTAK 811 also gives the same option. Both bank charges 100+tax for the card annually unless you upgrade to any other card. You you guys want to open an online account and if you will never maintain a balance above 1l then there are various banks available.
1. RBL BANK ABACUS ACCOUNT
2. IDFC BANK ONLINE SAVINGS ACCOUNT
3. PAYTM PAYMENTS BANK
