13.56MHZ RFID Reader/Writer Module V4.0





RFID  frequency identification is a non-contact object recognition technology, it can automaticlly recognize target and get relevant data through rf signal, so there are so many interactive projects which need to use RFID to achieve object recognition. Generally speaking, one basic kit of RFID general system mainly consists of three parts :

Tag : composed by coupling components and chip, every tag have only electronic coding, adhere to the target object identifier

Reader : equipment used to read (sometimes can write) tag information, can be designed for handheld or stationary;

Antenna : transmit rf signal between the tag and reader.

At present there are so many RFID module, and there are difference from the interface of Arduino, we design these two version of RFID module which connect with Arduino through serial port, and both of these two version have exact same function and connection mode, but the antenna is different.

Description

This RFID module is upgraded version from 13.56MHZ RFID Reader/Writer Module.

Compared with the old version, it supports more types of cards and has better reading/writing performance.

This RFID module is desgined based on MFRC522. It is a highly integrated reader/writer for contactless communication at 13.56MHz. It supports ISO 14443A/MIFARE mode and MIFARE Classic (e.g. MIFARE Standard) products. Contactless communication using MIFARE higher transfer speeds up to 848kbit/s in both directions.


 


We embeded an MCU on this module. By sending command via UART interface, you can make it work. Operation is very easy. Most work is done by the embeded MCU. There is also a SPI interface on the board. This is the MFRC's SPI. You can access MFRC directly via this inteface.

Features

1、Support 7-byte UID reading.

2、Support various Mafare cards

3、Outstanding Reading/Writing distance

4、Special Electronic Wallet Fountion

5、Control by Serial UART interface: Baud rate could be 2400bps ~ 115200bps, with default baud rate 9600bps

6、Configuration data is preserved in EEPROM against power cut off

7、Built-in 8K EEPROM for data storage

8、Easy to use, by sending simple commands users can control it to read or write cards

9、In compact command, command is as short as one byte

Parameter

1、Power Supply: 4.5V~5.5V, typically 5V.

2、Interface: UART (5V TTL) and SPI (3.3V TTL)

3、Size: 40mm x 50mm

 



Usage :

Baud rate could be 2400bps ~ 115200bps

Default setting :

    1) Baud Rate: 9600bps

    2) Parity bit: None

    3) Start bit: 1

    4) Data bit: 8

    5) Stop bit: 1


There are two kinds of command: Basic command and compact command. All the command are in Hex format. Please download manual for more information.

Connecting with Arduino is pretty easy. With Arduino Sensor Shield, just plug in and play. 

 





 

The working  principle of RFID is actually not complex, once the tag into the working area of card reader, card reader can read the data of tag by magnetic field generated by the antenna.

According to the specific use of different scene, we can use different types of tags, different types of tags have different range :
