QTnet Corporation (Head Office: Fukuoka City, Representative Director and President: Yoshio Ogura) announced the launch of 'QT PRO Secure Mobile [Medical Billing Only (My Number Emergency)]', which supports 'My Number Emergency Response' in its online medical billing connection service, and 'QT PRO VLAN (Guaranteed Type)' for large medical institutions, starting from March 31, 2026 (Tuesday).

QT PRO Secure Mobile [Medical Billing Only (My Number Emergency)]

### ■ Background and Purpose In urgent emergency situations where every second counts, 'My Number Emergency Response' (insurance verification using My Number cards) plays a significant role in accurately grasping information about injured or sick individuals. However, a major challenge has been the time required for complex communication settings and a series of operations in critical emergency scenes, due to the need for high-level security to strictly handle personal information.

Our company has utilized the technology of 'QT PRO Secure Mobile', a closed mobile line service for corporations, to solve these issues. We aim to reduce the burden on emergency personnel and provide a communication environment that users of ambulance services can use with peace of mind.

### ■ Service Features This service enables secure online qualification verification from inside an ambulance through a closed mobile line that does not use the internet.

* **Feature 1: [No Operation Required] Eliminates the hassle of ID/password entry and waiting for VPN connection** We have completely eliminated the complex VPN settings and ID/password entry that were necessary with conventional mobile connections. By simply turning on the terminal, it automatically connects to the 'Social Insurance Medical Fee Payment Fund and National Health Insurance Central Association', allowing emergency personnel to focus immediately on their primary emergency duties without spending time on communication settings.

* **Feature 2: [Information Leakage Prevention] Closed network connection not via the internet** Only the 'Social Insurance Medical Fee Payment Fund and National Health Insurance Central Association' are connected via a closed mobile line. This fundamentally blocks connections unrelated to operations, such as the internet, protecting patients' important personal information.

* **Feature 3: [Impersonation Prevention] Strict terminal authentication at the hardware level** Communication from any terminal other than those registered in advance is strictly prohibited. In the event of loss or theft of a terminal, communication can be immediately stopped by remote operation by an administrator, preventing unauthorized use through a dual physical and technical defense.

QT PRO VLAN (Guaranteed Type)

### ■ Service Features This service allows online billing and online qualification verification in a highly secure environment using a 'closed network' that does not use the internet. It also supports inter-site networks, making it ideal for large hospitals and medical institutions with multiple locations.

* **Feature 1: [Highly Reliable Infrastructure] ~Safety and Stability of Closed Network~** A closed network completely separated from the internet via a dedicated line connection ensures extremely high security. It also guarantees a certain communication speed, providing a safe and stable communication environment.

* **Feature 2: [24-hour Manned Monitoring] Peace of mind with constant monitoring and maintenance system** With a 24/7 manned system, customers' network is constantly monitored.
