RFID (Radio Frequency IDentification) refers to radio frequency identification systems. These frequencies range between 50 kHz and 2.5 GHz. The most widely used is 13.56 MHz.
The RFID system makes it possible to perform traceability, object identification (tracking) and access control functions.
The information is stored in a memory that can be accessed using a simple radio frequency link. This memory is in the form of an electronic tag, which contains an antenna and an integrated circuit. The tag contains the information associated with the object to which it is fixed. When a tag enters the field generated by the reader/smart antenna, it detects the signal and exchanges the data (read or write) between its memory and the reader/ smart antenna.
The applications are numerous:
Logistics: Goods Out, Goods In, transit, etc.
Tracking and sorting of baggage
Traceability in the food processing industry
Flexible assembly lines in the automotive sector
Automatic toll booths
Access control, etc.
The RFID system is also suitable for use in difficult environments (humidity, temperature, mechanical shock, vibration, dust, etc.).
