RFID stands for Radio Frequency Identification. This term refers to those technologies that allow the remote recognition of objects, animals and people using radio waves. A radio frequency identification system consists of two main components: a transponder or tag, and a reader. The tag is the label that is attached to the object. It is here that all the information related to it is contained and that uniquely identifies it. The data, stored in a microchip, can be read thanks to an antenna that receives and transmits radio signals to and from the RFID reader. The microchip and the antenna together form the RFID tag and are held together on a physical support. The reader is the device, either fixed or portable, used to read the RFID tag, able to convert the radio waves of the tag into a digital signal that can be transferred to a computer. In order to communicate between them, the tag and the reader must be tuned to the same frequency. Plastimark products are designed to be fully compatible with RFID technology, being able to count on the undeniable advantage provided by plastic not to interfere with the electronic reading of the label, something more likely to occur with metal trolleys (“Faraday cage” phenomenon).
