RFID is a general term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object wirelessly, using radio waves. This is sometimes referred to as contact-less technology and a typical RFID system is made up of three components: tags, readers and the host computer system.
About RFID technology, is a proven technology that has been around for a very long time. In the past, RFID used to be very expensive and limited in practical commercialized options, but with technological development, components can now be manufactured at a lower cost. RFID applications are now a cost-effective option that are able to solve problems that other alternatives such as bar codes are not capable of.
About RFID technology, RFID has been around since at least the 1970s. Up to now, it’s been too expensive and too limited to be practical for many commercial applications. But if tags can be made cheaply enough, they can solve many of the problems associated with bar codes. Radio waves travel through most non-metallic materials, so they can be embedded in packaging or encased in protective plastic for weather-proofing and greater durability. And tags have microchips that can store a unique serial number for every product manufactured around the world.
