Near Field Communication (NFC) is a non-contact identification and interconnection technology that enables short-range wireless communication between mobile devices, consumer electronics, PCs, and smart control tools. NFC is the abbreviation of Near Field Communication. NFC provides a simple, touch-based solution that allows consumers to exchange information, access content and services simply and intuitively. NFC consists of NFC module and NFC antenna.

A card reader (Card-reader) refers to an interface device that reads and writes a multimedia card as a mobile storage device in a computer. A commercial version of the reader can read security smart cards. Card readers are usually USB-connected and can access memory cards in a variety of formats, such as CompactFlash and SecureDigital. When the memory card is matched with an appropriate card reader, it can be used as a general flash drive. In addition, some printers also have integrated card readers. Users can easily use the printer to print photos. Some readers can only access one type of memory card, while others are all-in-one readers. Now, some memory cards have integrated the function of the card reader, and the user only needs to insert the memory card into the USB socket, and the computer can access the data in the memory card in real time.

The card reader (Reader) is a special device. There are slots for inserting memory cards and ports for connecting to a computer. After inserting a suitable memory card into the slot, connecting the port to the computer and installing the required driver, the computer treats the memory card as a removable memory, so that the memory card can be read and written through a card reader.

According to the type of compatible memory card, it can be divided into CF card reader, SM card reader, PCMICA card reader and memory stick reader. According to the port type, it can be divided into serial port card reader (very slow, very rare), parallel port card reader (suitable for early motherboard computers), USB card reader (fast speed, easy to use).

Card readers are divided into contact card readers, contactless card readers, single-interface card readers and dual-interface card readers, and multi-socket contact readers.

From the interface point of view, card readers mainly include: parallel port card reader, serial port card reader, USB card reader, PCMICA card reader and IEEE 1394 card reader. The first two card readers have basically been eliminated due to slow interface speed or inconvenient installation. USB card reader is currently the most popular card reader on the market, PCMICA card reader is mainly used in notebook computers, and IEEE 1394 card reader is not widely used because the supported interface is not yet popular.

Pins, also known as pins, are called Pins in English. It is a section of the end of the lead, which is soldered to form a solder joint with the pad on the printed board. It is the connection between the internal circuit of the integrated circuit (chip) and the peripheral circuit, and all the pins constitute the interface of this chip.

Further, the shape and size of the main body 10 are the same as the memory card supported by the card reader. The main flash memory or multimedia cards on the market are: TF card, SM card, CF card, MicroDrive, MemoryStick, MemoryStick PRO, MMC card, Micro SD Card, MiniSD card, SD and SDHC, XD card. According to the type of flash memory to be read, card readers are divided into single-function card readers and multi-function card readers. Single-function card readers generally can only read one type of flash memory card, such as TF card reader can only read TF card flash memory card, SM card reader can only read SM flash memory card; and multi-function card reader It is suitable for all kinds of flash memory cartoons, whether it is TF card, CF card or MemoryStick, it can be easily read. The short-range wireless communication module of this embodiment can be adapted to the above-mentioned single-function card reader or multi-function card reader, as long as the shape and size of the main body 10 are made so that the card reader adapted to it can read The same shape and size of the card can be achieved.

Table 1 shows the definitions of each pin of the short-range wireless communication module of this embodiment. Table 2 shows the definitions of each pin of the memory card of the card reader in this embodiment. It can be seen from Table 1 and Table 2 that the third pin and the fourth pin of the electrical connection port 20 are the same as the third pin and the fourth pin of the memory card of the card reader. The definitions of the four pins are consistent, and they are all power supply pins. The third pin and the fourth pin of the electrical connection port 20 and the seventh pin and the eighth pin of the memory card of the card reader are both input and output (I/O) pins. pin. The first pin of the electrical connection port 20 is defined as a DETECT pin, corresponding to the first pin position of the memory card of the card reader, but the definition is different because the memory card needs a data line connection, and the short-range wireless communication module of this embodiment does not need a data line connection function. The DETECT pin can help the card reader determine whether the short-range wireless communication module is inserted.
