Bhim UPI App from NPCI

On 30th December 2016, Prime minister Narendra Modi launched BHIM, which is an UPI app from National payment corporation of India (NPCI). For UPI transactions, any UPI enabled app can be used. Each UPI enabled app provides a distinct vpa address (this is similar to email address which you can use for sending/receiving payment). BHIM provides vpa address of the format yourname@upi

BHIM is a light weight application and is very simple to use. When installing first time a sms will be send to verify your mobile number. Unlike many other UPI apps, this app provides users with an option to select the sim if the phone is dual sim. Some other UPI apps require you to put the bank linked sim card in primary slot. To use this app your mobile number should already be linked with your bank account. Then the app will automatically get your bank details, you just need to set your UPI MPIN for each bank account to start using it.
