Indian private sector lender Yes Bank has joined forces with mobile payment solutions provider ToneTag to integrate sound-based contactless payments on its YES Pay mobile wallet.

ToneTag’s technology will enable Yes Pay users to make cardless and offline payments at merchant outlets through their mobile phones.

Yes Bank senior president and country head – digital banking Ritesh Pai said: “Contactless payments based on sound tones is something we haven’t seen before and is a very interesting concept brought forth by ToneTag.

“As IoT sees greater investment, consumers will become increasingly reliant on contactless payments, ToneTag is our bet at making Yes Pay Wallet future-ready.”

The ToneTag technology uses the in-built mic or speaker of any device to allow data transfer through sound waves. It supports a wide range of devices including PCs, PoS, EDC devices, wearables and mobile phones.

The software development kit of ToneTag incorporates a range of features including patented noise filters, three levels of encryption, tokenisation, white box cryptography and multifactor authentication.

ToneTag CEO Kumar Abhishek said: “With ToneTag, Yes Pay wallet users can enjoy an NFC like payments experience without the associated hardware dependencies, which is a significant improvement over current technologies such as QR codes that are being used in the market for in-store payments.”
