The Merchant App Notifies, but the QR Box Is Silent: What Should You Check?

If the merchant banking app receives a payment notification but the QR Box remains silent, check the payment record, QR Box status, Connect Hub Merchant Manager settings, notification permissions, and device connectivity to help identify where the notification path is interrupted.

What Should You Check When the Merchant App Notifies but the QR Box Is Silent?

1. Check the Payment Record

Confirm that the transaction appears in the merchant banking application's received-payment records and that the phone received the notification normally.

2. Check the QR Box Status

Open Connect Hub Merchant Manager and verify that the intended QR Box is shown as ready for use.

3. Check the Configuration

Verify that the merchant banking application and the QR Box intended to produce the audible alert are configured correctly.

4. Check Phone Permissions

Review the required notification-related permissions and Connect Hub Merchant Manager settings to confirm that they remain enabled as required.

5. Check Internet Connectivity

The phone and QR Box do not need to use the same internet network, but each required device needs working connectivity.

6. Test the QR Box Sound

If the direct test sound works but a real payment produces no sound, continue checking the notification path and related configuration.

Check One Stage at a Time Instead of Changing Everything

Capturing the payment record, device status, and relevant settings screens helps identify where the notification process stops and reduces trial-and-error troubleshooting.

If the merchant banking application shows an incoming payment notification but the QR Box remains silent, it is useful not to immediately assume that the QR Box itself is faulty. A payment notification passes through several parts of the setup before it becomes an audible alert from the QR Box. The simplest troubleshooting approach is to check each stage in order and identify how far the payment event has progressed. First, check the merchant banking application and confirm that the relevant payment appears in the received-payment records and that the phone received the application's notification normally. If there is no payment record or no notification from the merchant app, the issue is occurring before the Connect Hub and QR Box stages. If the merchant app is notifying normally, open Connect Hub Merchant Manager and check whether the relevant device is shown as ready for use. Also verify that the supported merchant banking application and the intended QR Box are configured correctly for the setup. Next, check the required permissions and settings on the Android phone, particularly those related to notifications and Connect Hub Merchant Manager. Even when the merchant banking application can display a notification on the screen, other phone settings can still affect whether that supported notification information can be used by the notification system. Internet connectivity should also be checked on both the phone and the QR Box. The devices do not need to use the same internet network, but each required part of the setup must remain connected. If one device loses connectivity, the payment notification may not reach the QR Box as expected. If the QR Box provides a sound-test function, test the box directly. If the test sound plays successfully, the speaker and audible-output function of the QR Box are working at that moment. Troubleshooting can then continue along the actual notification path, including the phone, Connect Hub Merchant Manager configuration, and QR Box connectivity. If the QR Box does not produce a sound even during a direct sound test, the device itself, its connection, and its operating status should be checked before repeating a real payment test. A useful troubleshooting method is to collect evidence from each stage, such as the merchant app's received-payment screen, the device-status screen in Connect Hub Merchant Manager, and the relevant permission or settings screens. This makes it easier to identify where the process stops without changing several settings at the same time. After any correction, perform another small real payment test and confirm both outcomes: the merchant banking application receives the payment notification and the QR Box produces the expected audible alert. Customer funds continue to go directly to the merchant's bank account. Connect Hub uses supported merchant-app notification information to help merchants recognize payment events through the configured notification system.
