We (Razorpay) recently did a webinar[0] on UPI, along with a corresponding blog post[1]. We also have an FAQ[1] up on the same.<p>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:<p>1. How well do banks implement UPI?<p>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]<p>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.<p>If anyone is interested on knowing more, I could probably answer a few questions here :)<p>[0]: <a href="https://youtu.be/0Yyxor0VYsE" rel="nofollow">https://youtu.be/0Yyxor0VYsE</a><p>[1]: <a href="https://razorpay.com/blog/what-is-upi/" rel="nofollow">https://razorpay.com/blog/what-is-upi/</a><p>[2]: <a href="https://razorpay.com/upi/" rel="nofollow">https://razorpay.com/upi/</a><p>[3]: <a href="http://www.livemint.com/Companies/ZSGu2hTgSn21bKzvY8hycI/Paytm-strengthens-top-management-for-payments-bank.html" rel="nofollow">http://www.livemint.com/Companies/ZSGu2hTgSn21bKzvY8hycI/Pay...</a>
