The Dept of Post is planning to launch a series of cards called theWhite Line pre-paid smart card by the India Post. They will work like debit cards to make transactions and bill payments at stores, mobile and internet. Post offices will issue these cards with denominations ranging from Rs 1000 to Rs 50,000. An easy to carry plastic money scheme. Will they be able to replace debt cards fro small time users or will they have a bigger market share ?
