| Zusammenfassung: | A card reader, a data reading and writing system, and a reading and writing method thereof are provided. The data reading and writing system is adapted to be connected to a host, so that the host can read and write data to an memory card through the data reading and writing system. The host uses one of a first type of communication protocol or a second type of communication protocol. The data reading and writing system includes a protocol determination controller, a communication interface controller, and a memory card controller. The protocol determination controller obtains a determination message of the host to determine that the host uses the first type of communication protocol or the second type of communication protocol. |
