Payment wallets as well as banks have been offering this facility to their customers, but lack of interoperability was hampering the growth in its adoption. For instance, if you have installed Paytm app on your mobile phone and the merchant displays say Freecharge QR code on her counter, a transaction is not possible. With Bharat QR, this will no longer be the case. Customers will not have to scan different QR codes depending on the payment network in use at merchant outlets. Similarly, merchants will only need to display one QR code at the storefront or through the acquiring bank’s mobile application. In future, the facility will be extended abroad too.
