RFID - Radio Frequency IDentification

Radio Frequency Identification (RFID) technology is an advanced identification system that uses electromagnetic waves to wirelessly detect items equipped with TAGs, i.e. radio frequency transponders.

One of the main advantages of RFID over traditional optical detection systems is its ability to detect multiple items simultaneously, with a range that can vary from a few centimetres to several metres. Unlike technologies such as barcodes, QR codes and DataMatrix, RFID allows products to be detected even when they are inside closed boxes or containers.

It is not necessary for the reader to be in direct line with the TAG: it is enough for the object to enter the reading range of the antennas to be detected, as opposed to optical systems such as 2D reader/scanners.

RFID: the engine of the IoT infrastructure

RFID plays a key role in the data supply chain, distinguished by its unique technical capabilities. It not only captures data accurately and quickly, but also acts as an enabler for the interconnection between people, objects, services and processes, becoming a key element in the IoT ecosystem.

This technology acts as a bridge between the physical and digital worlds, influencing the entire data lifecycle. From its acquisition, integration and analysis to its transformation into useful information for the consumer or end user, RFID optimises processes and increases efficiency.

How the RFID system works

RFID solutions, combining software and hardware, enable the automatic, instantaneous (hands free) collection and exchange of information. This technology can accurately track all phases of logistics management and all operations in the retail area, including:
