SAG Business Summary

Securitag Assembly Group Co., Ltd. (SAG) is a leading Taiwanese manufacturer specializing in the design and production of Radio Frequency Identification (RFID) transponders, including tags, labels, keyfobs, and smart cards. The company operates primarily through a hardware-centric revenue model, generating income from the mass production of RFID components and high-margin ODM/OEM services for global clients. SAG's business is segmented into specialized applications for healthcare (e.g., blood bag and test tube tracking), automotive logistics, industrial automation, and smart manufacturing. By integrating custom antenna design, material science, and proprietary in-house machinery, the company provides value-added solutions such as "RFID Plus One," which incorporates active sensors for temperature and environmental monitoring. SAG competes directly with global industry leaders such as Avery Dennison, Zebra Technologies, and HID Global, as well as regional players like Invengo; it distinguishes itself through its "under-one-roof" manufacturing flexibility and expertise in harsh-environment tagging. The company is led by Chairman Tseng Ying-Tang, who also serves as the Chairman of Siward Crystal Technology, a major strategic investor in SAG. The executive management team is anchored by CEO Terry Chiang (Chiang Hung-Yu), who holds an M.S. in Electrical Engineering from the University of Southern California and has been instrumental in transitioning the firm from a card manufacturer to a diverse IoT solutions provider. Key leadership also includes Vice President of New Product Business Yen Tien-Lin, a veteran with a background at Texas Instruments and Agilent, and Associate Assistant General Manager Chang Yu-Chi, who serves as the corporate spokesperson. SAG maintains a strong institutional backing, with Siward Crystal Technology and D&O Green Technologies Berhad holding significant equity stakes, reflecting the company's deep integration within the broader electronics and semiconductor supply chain.
