The invention discloses a read-write device and a control method thereof. The read-write device provided by the embodiment of the invention is characterized in that more than two slots used for holding memory cards are formed on a card socket; a control circuit board control one interface of a USB-HUB module to be corresponding to the memory card in each slot, and then read-write operation of the memory cards in the plurality of slots can be realized at the same time through the USB-HUB module, the control circuit board and a testing pin circuit board, so that the speed of read-write operation of a large number of memory cards can be improved, and the cost can be lowered; and the device is small in size, light in weight and high in reliability.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a memory card read-write device and a control method thereof. Background technique [0002] SD (Secure Digital, secure data) card is a memory card standard and is widely used in portable devices, such as digital cameras, personal digital assistants, and multimedia players. Due to the characteristics of portability and simple operation, SD card is very popular among consumers. With the popularization of SD cards, the application of reading and writing devices for reading and writing SD cards is becoming more and more extensive. [0003] With the development of information technology, people now have higher and higher requirements for real-time performance. Domestic banks have launched a pilot reform of mobile payment. One of the solutions currently adopted is to insert an SD card into the mobile phone. This SD card has The encryption protection function can be associated wit...
