Common RFID
Hardware Components
Handheld RFID Reader
This type of RFID reader is portable and lightweight. It allows you to read RFID tags
on the go. They typically come with an integrated or detachable mobile device and
custom mobile apps to connect the mobile device to the RFID reader. WIFI or mobile
broadband on the mobile device allows for RFID data to be transmitted to and from
cloud backends. Model in picture is the Zebra RFD 8500
Fixed RFID Reader
Fixed readers are used to read the RFID tags on items as they pass by or are placed
within the reader's read range. They are an unobtrusive way of tracking the movement of asset and
inventory items, monitoring production lines, etc. They can 7
be mains powered or have power over Ethernet. Fixed readers tend to require an
external antenna. Model in picture is the DENSO UR40 with built-in antenna
RFID Antenna
RFID readers use the antenna to transmit and receive the radio frequency signals.
Handheld readers typically have small antennas encased with the reader itself whilst
fixed readers require an external antenna. Antennas can come in different form factors
to suit different business applications. Model in picture is the Times-7 antenna
RFID Tags
RFID tags comprise of an antenna and an RFID chip. The chip stores information
such as the tag ID and other information. The antenna is powered on when it
receives a signal from the RFID Antenna, and receives and transmits radio frequency signals. RFID tags
are affixed to items to be tracked using an RFID reader and
antenna.
RFID Sensors
RFID Sensors are similar to RFID tags but have a sensor in addition to the chip and
antenna. The sensor is typically used to read environmental information such as
temperature, humidity, luminosity, etc. This information is sent along with the tag ID
when the sensor is interrogated by an RFID Reader and Antenna.
