MOVABLE DATA STORAGE MEDIUM AND DATA TRANSMISSION SYSTEM COMPRISING THE SAME

摘要

PURPOSE: A movable data storage medium and a data transmission system comprising the same are provided to perform one-to-one data communication and one-to-one communication by transceiving the data through RF communication without physical connection. CONSTITUTION: An antenna unit(110) recognizes another medium existing within a certain distance, and receives a propagation from another medium. An RF module unit(130) performs data communication with the RF module unit, and a memory unit(150) stores data communicated with the RF module unit. A controller controls the data communication with the RF module unit.
