I'm very curious as how it would now play out for 'digital wallets' like Paytm, MobiKwick, PayUMoney etc.
Paytm is a "Unicorn". It is perhaps valued at $2B with 125 Million users. http://www.business-standard.com/article/companies/paytm-val...
The digital wallets in India started with recharging balance for prepaid mobiles. When somebody recharges, Paytm and its ilk charges commission in the range of 2-5% from the Telcos.
A lot depends on how many customers adopt UPI and how well the banks implement it. If they respect what all NPCI has said, UPI could change a lot of things (affect wallets, improve transparency, cashless economy etc). However, a lot is hanging on few points:
1. How well do banks implement UPI?
2. Does NPCI open up UPI to more players? If yes, when and who? Wallets are the one that are most interested in this. [3]
3. Do they improve on UPI over time? As of now, UPI is missing a lot of its (promised) teeth. For eg: recurring payments, pre-authorized payments, split payments.
If anyone is interested on knowing more, I could probably answer a few questions here :)
