TAP OTAC by SSenStone is a comprehensive security and financial fraud prevention solution that utilizes One-Time Authentication Code (OTAC) technology. It generates dynamic, non-reusable authentication codes for user and device identification without requiring a communication network. The system allows for secure user authentication and card registration through a simple card tagging process, eliminating the need for fixed passwords or PINs. TAP OTAC can be used for various purposes, including card payments, financial transaction authentication, access control, and app/web logins. The authentication process involves embedding an applet in the IC chip of a payment card and an SDK in a financial app, enabling authentication by tagging the payment card to a smartphone with the app installed. This solution works across mobile operating systems and provides enhanced security and user convenience in both online and offline environments.
