India already does. For that fact mobile and card payment is a lot better executed than in USA. The difference is that it's a more recent happening and that is why they could learn from the mistakes of others and improve things. The problem is that a large part of the population grew up using cash and are more comfortable with it than with any form of mobile/card payment. The younger generation will prefer cashless transactions but being cashless only will leave a large part of the market alienated.
