Abstract

Disclosed is a data transmission system comprising a first device having first clock generator for generating a first clock signal for data exchange with a second device, second clock generator for generating a second clock signal for resetting the second device to be operable, and clock supplying unit for supplying the first and second clock signals to the second device, and the second device for performing data exchange with the first device in response to the first clock, the second device being reset by the second clock. It is thus possible to ensure data exchange using existing hardware such as a UART, while supplying a reset clock whose frequency will not be a multiple of 1200 bps even by frequency division by 2.sup.n, to the IC card. This data transmission system will therefore cope with both the demand for the ISO standardization and the use of existing hardware.
