The basic components of an RFID system are:
- Host computer with appropriate application software
RFID Tags :
RFID tags are tiny microchips with memory and an antenna coil, thinner than paper and some only 0.3mm across.
RFID tags listen for a radio signal sent by a RFID reader. When a RFID tag receives a query, it responds by transmitting its unique ID code and other data back to the reader. There are mainly two types of RFID tags—passive and active.
RFID Readers :
RFID readers, also called interrogators query RFID tags in order to obtain identification, location, and other information about the device or product the tag is embedded in. The RF energy from the reader antenna is collected by the RFID tag antenna and used to power up the microchip.
The third one is an antenna for receiving and transmitting the signal.Atlast we need softwares installed in system to access the details from receivers.
