====== RFID Radio Frequency IDentification Demonstration ======

Follow these two links for a description of the track and **[[thomasbc3|Control modules]]** used in this **[[exhibition_stand|cabinet]].**

RFID uses small glass encapsulated 'tags', these contain a transmitter that when energised by a field generated by the 'reader' transmit a unique number which is received by the reader and passed as serial data to a PC. In this demonstration the tags are mounted on various items of stock, when they pass the reader a Powerpoint presentation is caused to display a page appropriate to the item in question.
