13.56MHZ New RFID Reader/Writer
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.
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.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.Various host interfaces are implemented on this module :1) SPI interface2) Serial UART1、Supported cards : ISO 14443 TYPE A : MIFARE ® ,Mifare ® Classic1K,Mifare ® Classic 4K 2、Special Features : 1、Highly integrated analog circuitry to demodulate and decode responses2、Supports ISO/IEC14443A/MIFARE3、Typical operating distance in Reader/Writer mode for communication to a ISO/IEC14443A / MIFARE is 40~50 mm4、Supports MIFARE Classic encryption in Reader/Writer mode5、Supports ISO/IEC14443A higher transfer speed communication up to 848kbit/s
6、Control by Serial UART interface: Baud rate could be 2400bps ~ 115200bps, with default baud rate 9600bps7、With the chip ISO14443, it supports MIFARE standard encryption algorithm8、Configuration data is preserved in EEPROM against power cut off9、Built-in 8K EEPROM, easy to access it by sending commands10、Easy to use, by sending simple commands users can control it to read or write cards11、In compact command, command is as short as one byte12、Excellent EMC performance13、ROSH: Lead-free 3、Parameter :Power Supply: 4.5V~5.5V, typically 5V.Interface: UART (5V TTL) and SPI (3.3V TTL)Size: 40mm x 50mm4、Usage :Baud rate could be 2400bps ~ 115200bpsDefault 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 :Compatible Working With Arduino Size :13.56MHZ New RFID Reader/Writer Module List：1、13.56MHZ New RFID Reader/Writer Module ×1 2、13.56MHz Mifare RFID Card ×1 3、13.56MHz RFID Key IC Tag - B ×1 4、13.56MHz RFID Key IC Tag - A ×15、Arduino I2C/COM Cable 30cm ×1 Document Download： Click to download the Zip Document Click to download Testing with Arduino Zip Document List :1) : Manual2) : Mifare S503) : Mifare S704) : MFRC522 Datasheet5) : Click to download Testing with Shipping & Handling Policy
· Generally, It always take 7-14 business days to ship to USA, United Kingdom, Australia ,Canada , France and 7-25 business days to most other countries.
· And we always will ship our customers' parcel in two business days
(because our shipping agent have weekend from Saturday to Sunday ) after

value as you required.
· We ship to worldwide, so if your country or place is very far away,
please allow your parcel more time to arrive and we supply three kinds
of shipping way :
1、Standard Int'l Flat Rate Shipping (this way is default shipping way for free shipping mode)：this
standard post has the tracking number, but you can only track the
shipping more information of the goods on our official shipping
agent tracking website : espeedpost ,
but anyhow it is a reliable shipping way because it use the same
shipping carrier as Expedited Int'l Flat Rate Shipping. All of the free
shipping products use this shipping way.
2、Expedited Int'l Flat Rate Shipping Way：this
shipping way has the tracking number and the tracking number help you
to hold all of the status of your parcel situation, which means you will
know the exact status of your parcel anytime and anywhere. So if you
want to track your parcel parcel anytime and anywhere, please choose
this shipping way. You can track your parcel on three tracking website with the tracking number we update on : 1、 Espeedpost ; 2、Hongkong Post ; 3、Your Country Post Website.
3、Express Delivery Shipping Way：This
shipping way contain DHL、UPS、Fedex , if you need our products urgently ,
please use this shipping way and you can contact us and ask us the to
fix the shipping price and then we will use express delivery way for you
specially as soon as possible.
