POSTX is the official Korean partner of globally renowned tactical brands such as 5.11 Tactical, Mechanix Wear, Original S.W.A.T., Helikon-Tex, Condor, and Propper, supplying a wide range of products from military and law enforcement gear to civilian outdoor equipment.
The company operates one of Korea’s largest tactical equipment logistics centers, managing more than 300 domestic and international brands, as well as Korea’s largest tactical specialty online store, NETPX. Through a fast and efficient distribution system and rigorous quality control processes, POSTX delivers reliable products to the market. In addition, its offline stores provide an environment where consumers and professionals can directly experience and evaluate equipment in person.

Through years of experience in tactical equipment distribution and development, POSTX recognized the need for a domestically produced identification-friend-or-foe (IFF) device optimized for the Korean military’s operational environment. Existing foreign products posed not only cost burdens but also limitations in adapting to Korea’s terrain, climate, and operational methods.
In response, POSTX launched the development of SPAVER SIGNATY, aiming to enhance operational efficiency for Korean forces while contributing to the technological self-reliance of Korea’s defense industry. The result was the birth of SIGNATY, a Korean-made IFF device equipped with core technologies such as high-speed MCU-based precision synchronization, short-range wireless configuration, wireless firmware updates, and multiple programmable flashing patterns—features designed to provide immediate value in real combat and mission scenarios.

Since its launch, SIGNATY has continued to evolve through ongoing technological upgrades and quality improvements. Through industry–academic cooperation and the participation of specialized research teams, POSTX has secured both technical stability and structural reliability.
SIGNATY was selected as an outstanding case in the Ministry of Trade, Industry and Energy’s Technology Voucher Program, receiving official recognition for its technological excellence. It has also undergone pilot evaluations under the Ministry of National Defense’s Excellent Commercial Products Program, where its performance was verified in real military operating environments. Continuous improvements based on field feedback have further enhanced product completeness.
In 2025, SIGNATY obtained New Excellent Product (NEP) Certification, once again proving its competitiveness and quality as a domestically developed technology-based product. These achievements demonstrate POSTX’s growth beyond a distribution company into a specialized defense technology enterprise capable of independently developing and manufacturing tactical equipment.

SIGNATY is a 100% domestically developed IFF device that has been supplied to multiple branches of the Republic of Korea Armed Forces—including the Army, Navy, Air Force, and Marine Corps—as well as to several overseas customers. Its performance and reliability have been validated in real operational use.
By delivering superior performance at a more reasonable cost compared to foreign alternatives, SIGNATY has contributed to saving tens of billions of won in national defense budgets and has become a representative example of the potential and competitiveness of Korean-made tactical equipment.
Today, SIGNATY has established itself not merely as an identification device, but as a Korean standard for IFF systems that satisfies both defense technology independence and real-world operational effectiveness. Building on SIGNATY, POSTX will continue to invest in technology development and product advancement, growing as a company that shapes the future of tactical equipment in Korea.
