First Abu Dhabi Bank has introduced a new sound-based payment system using its digital wallet. The system, described as a first of its kind in the Gulf, allows customers to make payments using the banks Payit digital wallet app on their smartphone by listening to a sound and clicking pay. It uses sound waves to enable contactless payment and communication between devices ‘independent of hardware’. This system can be used with electronic cash registers, POS machines and devices and merchant mobile phones for payments in real time. The bank has partnered with fintech firms ToneTag and Marshal to launch the service. The bank’s head of payments Ramana Kumar said after successfully rolling out the UAE’s first QR-based payment system in March, the bank focused on launching a game-changing UAE-wide solution that is built around communication between smart devices.
