How is RFID a game changer ?

RFID is a method to store and retrieve data remotely. RFID tags are small objects which can be sticked or incorporated into objects or products. This technology saves time for the users and allows a quick reading of the data.

What’s RFID?

RFID stands for Radio Frequency Identification and is a method to store and retrieve data remotely. RFID tags are small objects, such as self-adhesive labels, which can be sticked or incorporated into objects or products and even implanted into living organisms (animals, human body).

The RFID technology first appeared in 1948 for military purpose: identify enemy and allies’ planes. In the 80’s, the RFID got miniaturised and the price dropped significantly, which resulted in RFID being used in civil environments. Unfortunately, it did not meet the expected success.

In late 2000s some grocery stores decided to use it intensively to manage their supply chain and imposed it on their suppliers. This marked the beginning of the RFID revolution. Since then, the scope of application of RFID has grown steadily and can be now found everywhere (clothes, food packaging, furniture, cars…)

How does it work?

A system of radio-identification is composed of two entities which communicate between them:

  • An RFID tag, which is composed of an antenna and a chip containing information, is fasten on the element to be identified. These can be read remotely (from 10 m to 200 m according to the type of chips).
  • An RFID reader, also called interrogators. It is composed of a radio frequency module for transmission and reception, a control unit, an antenna, and an interface to transmit data to a terminal.

They communicate by radio frequency. Indeed, when the tags enter the detection zone of the antenna, they transmit their information by radio frequency, the frequency being the characteristic which allows to establish the communication between the chip and the antenna. The antenna then transmits the information to the reader, which converts this radio wave into usable data.

The advantages?

This technology saves time for the users and allows a quick reading of the data. 

  • Range: you do not need to see the tag to read it, unlike barcodes or data matrix. 
  • Lifetime: you can read them thousands of times.
  • Speed: you can read simultaneously hundreds of tags.
  • Automation: you don't need a person to read it, you just have to pass under a portal and the detection is done automatically.
  • Scope: there are thousands of different tags for different usage (nailing label to be placed in a wooden structure).
  • Price: an RFID Tag is really affordable nowadays and can be used almost anywhere.
  • Integration: easy to integrate into technologies. In general, products already have tags, they just need to be converted into an RFID tag.
