What do cattle, pharmaceuticals, automobile production, tolls, pets, clothes and people have in common? You may think this is a random list of objects; however all of them are interrelated through a technology call Radio Frequency Identification. This is a small device designed for tracking in real time any type of object. The picture to the right shows the size of the Radio Frequency Identification (RFID) tag next to grains of rice. That’s pretty small! Some RFIDs don’t even require a source of power. The device works by receiving and transmitting a signal through radio frequency waves. According to a RFID journal website, the cost of an RFID tag starts at $0.05 each and can go up to $100 each, depending on the application and use of the tag.
This technology exceeds bar codes in the easy use of scanning objects, which makes things more efficient and effective. Unlike bar codes, the RFID tag can be read through a box or container. Multiple tags can also be read concurrently. For example, while grocery shopping, the RFID can scan all your items that are in your cart simultaneously. RFID can offer several opportunities in different industries such as hospitals, libraries, schools and sports. It can be used for inventory management, product tracking, and identification.
A disadvantage of the RFID is the privacy concern. Customers that are purchasing items with a RFID tag may be concerned that their privacy will be jeopardized because items purchased with the tag on them can possibly be tracked even within the customer’s home. Who wants to be tracked down?
Over the next few months, expect to learn more about the newest innovations in the Radio Frequency Identification field. Tune in to hear interesting stories on how the RFID has been creatively used in different fields such as: implantation into living organisms, pharmaceutical purposes and business innovations.
