Micro card and passive commutate device suitable for micro card

摘要

A micro card and the passive commutate device suitable for micro card, wherein the micro card is a micro card designed in a theory of micro and is configured with micro controller and substrate of repeating read-write memory and transmit part connect electrically with the substrate. The transmit part of the micro card is designed into a universal interface to support the transfer of sign of interface of various application device. The micro card link with a pre-set passive commutate device, a first standard interface disposed on the passive commutate device. The first standard interface is for memory card interface, and connect electrically with universal interface and couple with memory card of application device. By micro card sense automatically, judge the interface type supported by the passive commutate device to switch to corresponding work model to save outer date to repeating read-write memory of micro card. 5.(1). The representative drawing of the present invention is FIG. 2. (2). The brief description of the representative symbol of the representative drawing of the present invention: 1: micro card 103: transmit part (universal interface) 2. passive commutate device 20: main body 201: first standard interface 202: receive zone 203: second standard interface
