'RFID' Makes Keeping Track of Inventory Easy

If you've ever marveled at the number of products and companies that use bar codes, you get an idea of how popular RFID tags may be. RFID, short for radio frequency identification, is the next evolution of the bar code. These tags, which can be used in countless applications, allow businesses to monitor and track the presence of physical objects. It's best explained with an example. RFID tags, for instance, would allow a shipping company to easily see how many containers are in the port waiting to be unloaded and how many are empty. These tags would allow retailers to count the number of boxes on a shelf and know where they are located in a store. Source: USATODAY / Captain Obvious
