*3 *6MHz RFID Mifare Read Write Module Kits 6cm

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.
