Embodiment 1

[0029] see Figure 1-8 , in an embodiment of the present invention, a memory card device with NFC function is composed of two parts, including an SD storage function module and an identity recognition function module, and the SD storage function module includes a first interface unit, a control unit and a storage unit; the identity recognition function module includes a second interface unit, a processor unit, a program storage unit, a data storage unit and a work storage unit; wherein, the first interface unit and the first interface unit of the SD storage function module and the identity recognition function module The two interface units are located on the card body of the memory card device; the control unit and storage unit of the SD storage function module and the processor unit, program storage unit, data storage unit and work storage unit of the identity recognition function module are all encapsulated in the memory card The inside of the device; the external dimension...

Embodiment 2

[0031] see Figure 1-8 , the difference between this embodiment and embodiment 1 is:

[0032] In this embodiment, the interface part of the memory card device includes a first metal contact (corresponding to "1" in the figure), a second metal contact (corresponding to "2" in the figure), and a third metal contact (corresponding to "2" in the figure). "3" in the figure), the fourth metal contact (corresponding to "4" in the figure), the fifth metal contact (corresponding to "5" in the figure), the sixth metal contact (corresponding to "6" in the figure "), the seventh metal contact (corresponding to "7" in the figure) and the eighth metal contact (corresponding to "8" in the figure), wherein the first metal contact is used to store the power signal of the function, The second metal contact is used to transmit the ground signal of the storage function, the third metal contact is used to transmit the data signal of the storage function, the fourth metal contact is used to transm...

Abstract

The invention relates to the field of storage devices, in particular to a storage card device with an NFC function, which comprises an SD storage function module and an identity recognition function module, and the SD storage function module comprises a first interface unit, a control unit and a storage unit; the identity recognition function module comprises a second interface unit, a processor unit, a program storage unit, a data storage unit and a work storage unit; an interface part of the memory card device comprises a memory function interface and an identification function interface. The method is used for solving the problems of space structure waste and complexity caused by double NANO SIM card holders in the intelligent terminal; an SD card storage function can be used on one NANO SIM card seat at the same time; the SIM card identity recognition function and the NFC function can be used separately and independently and can also be used simultaneously, the size of the terminalcan be miniaturized, the optimization problem of the terminal space is solved, and the memory card has the mobile payment function while meeting the requirement of file storage.

Description

technical field [0001] The invention relates to the field of storage devices, in particular to a storage card device with NFC function. Background technique [0002] In real life and work, smart terminals, as a communication tool, are more and more widely used. In existing smart terminals, there are usually subscriber identification cards (SIM cards, Subscriber Identification Modules) and memory cards (SD cards). When we use terminals, SIM cards are used to identify user identities, and Micro SD cards are used to store user data. With the development of technology, the volume of the terminal is getting smaller and smaller, and the structure is more and more complex. Multiple physical interfaces (card holders) are provided to be compatible with the structure of SIM cards and Micro SD cards, which is a kind of compact smart phone. waste. [0003] In order to make more effective use of the space in smart terminals, people have invented NANO SIM cards and Micro SD cards. Mor...
