  • Payment Solution

    OTAC technology can generate virtual dynamic card information without a network connection, adding an additional layer of security in the payment process. This patented technology is a Card-Not-Present (CNP) security solution that replaces static card information with variable dynamic card information, providing users full control over their security and finances.

  • Connected Car Solution

    With current digital key solutions, linking with car-sharing services to receive keys and start vehicles requires a network connection. Thus, there are potential problems when vehicles are in underground or remote areas with poor access to a network. Using OTAC technology, digital keys can be activated and shared with authorized users without any issues regardless of driver or vehicle location.

  • IoT Solution

    Using dynamic codes, OTAC helps devices easily identify and authenticate users and other devices. When a user generates OTAC on a local device, it can be delivered through various channels such as voice recognition, keypads, and Bluetooth. The OTAC algorithm is small enough to be loaded onto any chip for enhanced security.

  • M2M Solution

    Businesses today are moving towards a microservice environment with reliable end-to-end infrastructure. However, certification processes are as inconvenient as ever because they involve multiple rounds of time-consuming communication. Furthermore, microservices that rely on access control could become overwhelmed by authentication services. OTAC provides one-way identification and authentication between users and devices in end-to-end infrastructure, significantly reducing turnaround time and simplifying the steps involved.

  • Military Defense Solution

    During a war or battle, it is very difficult to identify and differentiate between allies and targets. At present, we use devices that transmit static information to identify allies. But in cases of hacking, this method poses risks of transmitting intact information to the enemy. OTAC generates dynamic codes on local devices even in offline environments, eliminating the risk of being hacked. Devices with the OTAC algorithm application can transmit dynamic codes that keep changing to safely identify allies wherever they are located.
