Trillbit Data-over-sound technology has a two-way full-duplex mode of communication, for the near-field communication applications.

This addresses a critical limitation of NFC or QR code. Enabling two-way data transmission means that devices can receive the confirmation back.

This makes any transaction very secure.
for example, encrypted key exchange for secure financial transactions,or sending  confirmation receipts to a merchant or buyer.

Our technology works across devices and cross OS and requires no additional hardware, which makes it a powerful alternative to peer-to-peer payments and transaction.
