Why a sound box

Busy counters can't watch every screen.

A sound box speaks every payment out loud, so merchants never have to check a phone.

  • Missed notifications: phones stay in pockets during a rush
  • Fake payment screens: confirmation comes from your gateway
  • Noisy places: a dedicated 5 W speaker is heard over the crowd

How it works

From scan to sound in four steps.

  1. 01

    Customer scans & pays

    Any wallet app scans the merchant's QR code.

  2. 02

    Gateway confirms

    Your payment system calls the Cpay IoT Broadcast API.

  3. 03

    Cpay IoT pushes

    The message is routed to the right device over MQTT.

  4. 04

    Sound box announces

    The amount is spoken and the result is reported back.

From the first import to the millionth broadcast.

Dashboard

Your whole fleet on one screen.

Live KPIs for devices, online rate, payments and broadcast success.

  • Task push history with success, failed and pending
  • Online status report for 7, 14 or 30 days, exported to Excel
Cpay IoT dashboard
Device management

Import, find and group every device.

Status, firmware, voice pack, battery, signal and location are reported automatically and shown in seven tabs of the device detail.

  • Three ways to import: Excel, quick entry or a serial range
  • Split by store or sub-merchant; move between organizations
  • Search by serial, model, group or status; export to Excel

Payment broadcast

Every payment, heard and recorded.

Paid, received, released and broadcast: every step is timestamped, usually within seconds.

  • Transaction record with amount, status and timestamps
  • Push request log: payment, QR code, OTA, online, offline
  • Channel mapping: your gateway's codes to the voice played

OTA upgrade

Upgrade thousands of devices in one task.

Firmware and voice packs reach every device over the air. Offline devices catch up the moment they reconnect.

  • Upload firmware or a voice pack in Software Manager
  • Target by model, group or serial range, with a time window
  • Track success or failure per device, with the reason

Advertising

Turn every broadcast into an ad slot.

Play voice ads at start-up, before or after the amount, or on up to four schedules a day; push image carousels to screen devices, or switch all ads off in one task.

Remote operations

Remote operations, no site visits.

Change settings in bulk, such as the heartbeat interval or server address, sent as JSON to the devices you choose.

  • Reboot, lock or unlock one device or thousands
  • Act from a device list or an Excel file
  • Every task tracked: pending, delivered, success or failure

Map and monitoring

Know where every device is, and if it's online.

A value-added service for large fleets.

  • Clustered map: click a device for its status and model
  • Online rate for the last 14 days, exported to Excel
  • Every online and offline event, per device

Architecture

How Cpay IoT works with your systems.

Secure by design with signed APIs, HTTPS and TLS; clustered MQTT and containerised services scale out with your fleet, and server health is monitored with e-mail alerts.

  1. 01

    Your payment gateway

    Sends each payment result, or runs the fleet from your own platform via TMS APIs.

  2. 02

    Cpay IoT platform

    Signed Broadcast and TMS APIs, a push and task engine, and the console.

  3. 03

    MQTT service

    An EMQX cluster, or AWS, Alibaba Cloud or Tencent Cloud IoT, over TLS.

  4. 04

    Sound boxes

    Announce the amount and report the result back.

Multi-level control, secure by default.

Open API

Open APIs for fast integration.

One broadcast API plus TMS APIs. Each organization gets its own channel ID, key and callback URL.

  • Broadcast income and push dynamic QR codes
  • Fetch, update and batch-import devices
  • Firmware OTA, remote control and real-time ad tasks
  • Transaction history and task result callbacks
