RFID technology

What is passive RFID technology?

RFID stands for Radio Frequency Identificationis a method of storing and retrieving data remotely, using radio waves. In other words, it detects objects or other items, static or moving, using electromagnetic fields, via a reader, antennae and RFID chips. The working frequencies of passive RFID are very similar to those of WiFi and Bluetooth. 

The RFID system is composed of two entities: a mobile or/and fixed antenna and a tag, usually represented as a label. It is also common to see it attached to warranty/banking cards or other solid and robust material to protect it from shocks. An RFID tag is composed of an electronic chip and an antenna, all placed on a substrate, which allows them to receive and respond to radio frequencies sent by the transmitter.

Tags are affixed on the element to be identified and can be read without being seen directly, unlike barcodes, which allows a mass reading and distance (from a few centimeters to several tens of meters depending on the size of the chip). 

RFID technology has proven itself in many environments and real-life use cases. At Solid, we work to advise and support our customers in the implementation of this technology within their organization. Rapid and visible results in terms of process simplification and automation of traceability flows are noted by management and operational staff.
