As the global information age grows, the importance of information protection increases and the interest in security methods is growing.
As a result, technologies that require security are evolving at each airport, such as immigration systems, issuance of resident cards,
bank security, data center security, and access to residential spaces. Incheon International Airport has already established and operated
an iris-aware security system, and many of these biometric systems are emerging in life.

At the request of the client company that develops the security and surveillance system, PIEZO Technology Co., Ltd. develops/delivers
or transforms the iris recognition auto-focus and mirror-type modules using its TULA (Tiny Ultrasonic Linear Motor) to play an important role as the best.
The modules using this TULA have high speed, long stroke so that high-accuracy surveillance and surveillance systems can be developed.
