Sign'Buy develops a handwritten signature-recognition technology that is based on a dynamic biometric analysis of human finger traits such as direction, pressure, and speed.

Using a smartphone screen as an input device, users can sign by drawing their signature, a process that Sign'Buy refers to as a finger signature (FS).

The company aims for its FS product to become the preferred biometric authentication solution for various platforms including personnel internet-based systems, banking processes, and IoT access control.
