Those of us who have no experience with manufacturing environments or shipping warehouses probably cannot imagine the immense effort required to “keep track of everything,” for lack of a more sophisticated description. I’m assuming that bar codes and other techniques are still widely used, but RFID (radio-frequency identification) offers significant advantages.
So what exactly is RFID? It’s the same general idea as a bar code: We want to attach information to a physical object. Bar codes accomplish this using black-and-white patterns that are optically scanned and interpreted as data. RFID accomplishes this via tags that are attached to or embedded within an object; the tag contains digital data that can be accessed via electromagnetic radiation.
