RF-ID Barcodes

The RFID devices work in the same purpose as a bar code or a magnetic strip on a credit card or ATM card - provide a unique identifier for that object. Similarly, RFID devices must be scanned in order to retrieve the information associated with that identification tag.

But RFID seem to work better than Barcodes. Among them is that the RFID devices do not have the difficulty of being read or scanned at a precise location and position. In contrast, RFID devices will work within a few feet (up to 20 feet for high-frequency devices) of the scanner. As an example, groceries or purchases can be placed in a bag, and the bag set on the scanner. There, all the RFID devices can be queried at that instance and a summation of the purchases can be immediately generated.

Although RFID technology has been available for more than fifty years, it has only been recently that manufacturing RFID devices has become economically feasible. Another reason is that it has taken so long for RFID to come into common use because of a lack of standards in the industry, where most applications tracked items only within the confines of one company.

Some systems have combined RFID tags with sensors of different kinds. This allowed the tag to report not simply the same information over and over, but identifying information along with current data picked up by the sensor. For example, an RFID tag attached to a leg of lamb could report on the temperature readings of the past 24 hours, to ensure that the meat was properly kept cool.

With this capability, warehouse automation reaches a higher level of monitoring and control. As a result, it expands the meaning and scope of warehouse automation from the simple inventory solution to safety and security, and, in this case, to that of an intelligent storage facility.
