RFID technology heads ahead with more innovations
Have you ever heard the alarm in a mall or a market? And you come to know that someone trying to shop lift was caught. Have you tried to know what actually worked? It is the radio-frequency identification tag (RFID) that caught the culprit. Radio waves from a transmitter near the store’s door were picked up by the antenna in the label and the response was the alarm. Though this technology is not something new, but researchers are trying out new ways to add more facets to it.
One such instance relates to a pair of Rochester engineers, Mark Amico and Paul Hosier. Amico and Hosier, who have received a number of patents for their work, have described a method of using RFID tags to monitor printer’s components. The technique once incorporated, will not only alert huge printing machines but also home printers. So, if you have this technology incorporated in your printer, you will never face a situation where in the ink gets over while you are trying to print something important. The most amazing thing with these tags is that they can be attached to a consumable as well. And when attached, the computer can tell you when the supplies are going low or when it needs to be supplied with more.
Another very important innovation is to attach RFID tags to documents and papers, which is a unique way to keep track of important documents.
But this is not the end; Amico explains how milk cartons can also be tagged. By doing so, the refrigerator can tell you how long the carton has been there, if you need to refill it, or when the expiry date is. In fact, the day is not far when tags on your clothes can tell you, if you need to wash them with hot or cold water or an alarm goes when you put a colored shirt with a bunch of whites.
These ideas seem out of a science fiction, but with the progress made by Amico and Hosier, these fascinating ideas will be a reality soon.
