We're Launching 'Sound Pay'! Sounds good?

I believe Google use it for onhub. And a bunch of apps already use it for some form of authentication or connectivity. Paytm is latest.

"Consumers will soon have the option of clicking the 'sound pay' icon in the Paytm app," Nitin Misra, head of products at Paytm, told ET. "It will transmit ultrasonic sound at a certain frequency and it carries data. The data will include how much to pay and the customers credentials."
