Just as people use RFID as they go about their daily lives, objects also use this technology, as they transit from manufacture to storage and finally the point of sale.
Like us, they also carry RFID tags. The difference between objects and us is that they don’t “voluntarily” present their RFID tag or card when asked. These tags are therefore read in very different conditions and often require greater detection distances.
RFID (Radio Frequency Identification) is an Automatic identification technology which uses radio-frequency electromagnetic fields to identify objects carrying tags when they come close to a reader.
RFID uses several radio frequencies and many types of tag exist with different communication methods and power supply sources, and may be a unique identifier.
RFID tags generally feature an electronic chip with an antenna in order to pass information onto the interrogator. The assembly is called an inlay and is then packaged to be able to withstand the conditions in which it will operate. This finished product is known as a tag, label or transponder.
The information contained within an RFID tag’s electronic chip depends on its application.
