RFID Technologies

What is RFId technology and what is it for?

English acronym for Radio Frequency Identification , RFID is the technology that allows the unique identification, remotely and wirelessly, of things or people, both static and in motion, thanks to radio frequencies.

RFId is one of the technologies underlying the IoT (Internet Of Things or Internet of Things) as it is able to interconnect people, objects, services and processes, connecting the physical world to the virtual one.

RFID systems are basically composed of two components: transponders (called TAG ) and READER with antennas.

RFId TAGs: what are they and how do they work?

RFID transponders (TAGs) are radio frequency devices equipped with a microchip with non-volatile memory and an antenna, capable of interacting at certain electromagnetic / electrical frequencies generated by special READERS and ANTENNAS.

RFID TAGS are mainly divided into: ACTIVE RFID TAG (powered by batteries) and PASSIVE RFID TAGS (without power batteries).

Passive RFId TAGs are the most common and economical, through their integrated antenna they capture the energy needed to activate and transmit / exchange data with the Reader which generates the necessary electric / magnetic field. There are hundreds of types of passive RFId TAGs, the simplest are similar to adhesive labels called "smart labels" or "smart labels".

RFId readers and antennas: what are they and how do they work?

RFID READERS are electronic devices capable of generating specific frequencies that are propagated in the air through special antennas. There are various types of readers and antennas on the market, which can be divided into three main categories:

  • Desktop reader : small and cheap products, usually connected to the USB port of a PC. Power is usually limited for reading / writing single tags quickly and economically
  • Handheld readers : compact products of various shapes, with different complexities and costs. There are cheap products that can be connected to the USB ports of a PC and very complex products (self-powered mini-computers) that can simultaneously manage RFId, barcode, QR code readings, etc. and equipped with a screen can connect in WIFI, Bluetooth and GPRS mode. In the UHF environment, these readers have limited reading performance due to their size, compared to fixed readers.
  • Fixed readers : products of high power, used for industrial uses and normally fixed in a stable way. Readers are available integrated in the antennas or single readers that can be connected to a wide choice of antennas, which can guarantee the maximum possible performance, especially for massive readings. The overall performance of an RFId reading system always depends on the adequate mix of the three components: reader, antennas and Tags used.
