Abstract: This paper researches and analyzes the performance requirements of Card Operating System(COS), and proposes the ideas and methods of COS based on the hardware platform of ARM smart card. The implementation principles of STK application and OTA technology are discussed. The system utilizes OTA technology to implement STK menu of card remote updating. The structure of this system is reasonable, has complete function and high compatibility. It will be widely applied in the future.

Key words: smart card, Card Operating System(COS), Over The Air(OTA) technology
