ToneTag is a payment protocol that allows users to complete transactions via sound-based signals, NFC, or Bluetooth. It is designed to detect user proximity and intent to trigger payments without requiring customers to scan a QR code or manually open an application.
The protocol is intended for businesses operating physical touchpoints, such as retail stores, fuel stations, and transit hubs, as well as OEMs developing smart IoT devices. It supports payment methods including UPI and card payments.
A technical feature is its edge-based processing, where transactions are handled locally on the device. This is designed to support payment functionality in environments with unreliable internet connectivity, as transactions may be queued and synced when connectivity is restored.
Buyers should confirm how the SDK and API fit into their existing POS infrastructure and verify if their hardware supports the necessary audio or proximity requirements.
