UPI 2.0Edit

On 16 August 2018, UPI 2.0 was launched which enabled users to link their Overdraft accounts to a UPI handle. Users were also able to pre-authorise transactions by issuing a mandate for specific merchant. 2.0 version included a feature to view and store the invoice for the transactions. There's also an added feature of AutoPay facility for recurring payments.[6][7][8]

Supported banksEdit

The website of National Payments Corporation of India (NPCI) lists the banks that facilitate UPI.[9] Banks here are termed as Payment Service Providers (PSP) - listed with their UPI application and handle - and issuers.[9] PSP includes those banks which have their own mobile application to facilitate transaction and issuers include banks which don't have their payments interface and rely on third party software for transaction using UPI.


There are talks happening to operate UPI in United Arab Emirates and Singapore which has sizeable Indian expatriates and for ease of payment for Indian tourists travelling abroad. Committee on digital payments led by Nandan Nilekani had suggested that NPCI should internationalise payment services like UPI, RuPay and BHIM.[10] NPCI is planning to link UPI with standalone mobile wallets so that users can transfer money from one provider to another one which till now is restricted due to use of closed source technology. There is also provision for off-line UPI payment through the use of near field communication (NFC).[11]
