Tung-Ngern with Connect Hub: Payment Notifications for Merchants

Explore Krungthai’s Tung-Ngern merchant app from a practical shop-operation perspective, including QR payment acceptance, incoming-payment notifications, how it works with Connect Hub In-App, and observations from Connect Hub testing.

What Does Tung-Ngern Provide for Merchants?

Receive Payments with PromptPay QR

Krungthai's official merchant information states that Tung-Ngern merchants can receive payments through PromptPay QR and can obtain a countertop QR sign from a Krungthai branch or download a QR within the application.

For Individual and Corporate Merchants

Krungthai states that both individuals and legal entities can register as Tung-Ngern merchants through its website, with a Krungthai savings or current account required.

A Digital Payment Tool for Merchants

Krungthai presents Tung-Ngern as a merchant application for receiving payments through digital channels and supporting day-to-day merchant sales operations.

Tung-Ngern with the Connect Hub In-App System

Tung-Ngern is one of the merchant applications supported by Connect Hub's In-App system and one that we have tested extensively with our system. When used with Connect Hub Merchant Manager, notification information from the supported app can be used to assist payment awareness and shop operations. Connect Hub does not alter the financial transaction path or receive customer funds on behalf of the bank.

Observations from Connect Hub Tung-Ngern Testing

Sub-Account Support Observed in Testing

In Connect Hub testing, we have observed support for up to 10 sub-accounts. This is an operational observation from our testing and is not presented as information published on the bank's public page referenced for this article.

Payment to the Main-Account QR

In Connect Hub testing, when a payment is received through the main-account QR, we observed message and audible notifications on the main account and all sub-accounts.

Convenient Return to the Foreground

In our testing, even after Tung-Ngern has operated in the background for several hours, bringing the application back to the foreground generally allows the merchant to continue without having to sign in again. This makes it convenient for shops that occasionally return to the app during the day.

Audible Alerts While in the Background

From Connect Hub testing, Tung-Ngern is one of three bank applications we have observed providing audible alerts while operating in the background.

A Practical Day-to-Day Workflow for Merchants

For shops using Tung-Ngern with Connect Hub, the application can be left operating in the background during the day. From our testing, merchants can generally bring Tung-Ngern back to the foreground to review transactions without being forced to sign in again after several hours in the background. Alternatively, merchants can use Connect Hub Merchant Manager to review information relevant to Connect Hub operations whenever convenient.

Distinguishing Bank Information from Connect Hub Observations

Information from Krungthai

Information about Tung-Ngern merchant registration, the required Krungthai account, and PromptPay QR payment acceptance is based on Krungthai's public merchant information.

Connect Hub Observations

Sub-account capacity, main-account notification behavior, background operation, foreground return behavior, and audible background alerts are observations from Connect Hub testing. These behaviors may change when the bank updates the application or related services.

Tung-Ngern is a merchant application from Krungthai Bank designed to help shops receive digital payments. According to Krungthai’s official information, merchants can receive payments through PromptPay QR, and both individual merchants and legal entities can apply for the service. A Krungthai savings or current account is required for registration. For Connect Hub, Tung-Ngern is one of the key merchant banking applications supported by the In-App system and one that we have tested extensively in practical shop environments. Our focus is not on replacing the bank’s payment process, but on helping merchants make better use of the payment notifications generated by the supported application during day-to-day operations. Connect Hub does not receive, process, or act as an intermediary for customer funds. Financial transactions remain under the bank’s process, and payments are transferred directly to the merchant’s bank account. Connect Hub works with notification information from supported merchant applications to assist with payment awareness and merchant operations. From our testing, Tung-Ngern also shows several practical characteristics that are useful for merchants who keep the application running throughout the day. We have observed that the app can remain in the background for several hours and can generally be brought back to the foreground without requiring the merchant to sign in again. We have also observed audible payment alerts while the app is running in the background. These characteristics make Tung-Ngern particularly convenient for shops that occasionally need to return to the banking application during the day. Merchants can check transactions directly in Tung-Ngern when needed, or use Connect Hub Merchant Manager to review information relevant to Connect Hub operations. Connect Hub testing has also observed support for up to 10 sub-accounts. When a payment is received through the main-account QR, we observed message and audible notifications on the main account and all sub-accounts. These sub-account and notification behaviors are observations from Connect Hub testing and should not be interpreted as bank-published specifications. Application behavior may change when Krungthai updates the app or related services.
