Ic card and method of initializing ic card

An IC card and a method for initializing the IC card are provided to support fast communication of a contact type and RF(Radio Frequency) communication of a contactless type while keeping contact point arrangement following an ISO(International Organization for Standardization) 7816 standard, and store large capacity data by using a flash memory mounted in the IC card. Multiple contact points(100a-100h) include a pair of RF contact points, and at least one communication contact point. A microprocessor(130) selects a slow or fast protocol, and outputs a response by processing data recorded in a memory based on a command inputted through the RF or communication contact point determined by the selected protocol. A fast card interface(120) communicates the command/response through the communication contact point by using the fast protocol. An IC card interface(125) communicates the command/response through the communication contact point by using the slow protocol. A contact point allocator(110) connects the communication contact point determined by the selected protocol to the IC card interface or the fast card interface.
