As you perhaps already know, RFID is an acronym for ‘Radio Frequency Identification’ – it is the device that makes ID tags work – but you probably only started hearing about it over the last couple of years. So, how much do you know about RFID? In this piece of writing, I want to take a short look at the history of this seemingly new invention, which has intruded upon almost every aspect of a city-dweller’s life and that of many animal farmers as well.

RFID stands for ‘Radio Frequency Identification’. It involves the utilization of an object normally made of plastic or metal to identify an object in a similar way to bar codes identify items. In fact, they are used in a very similar way to bar codes and, at least for the foreseeable future, are usually used in conjunction with bar codes.
