Why RFID New ways of using RFID are constantly being developed all over the world. There are many of different advantages to RFID in comparison to other technologies like bar code systems. Some of the typical advantages of RFID in general are: The read-only Tag code data is 100% secure and can not be changed or duplicated. Very robust Tags that can stand extreme conditions and temperatures. Tags are available in a great range of types, sizes and materials. No need for physical contact between the data carrier and the communication device. The Tags can be used repeatedly. Relatively low maintenance cost. No line-of-sight necessary to read/write data. This makes it possible to use tags in harsh environments and in closed containers/structures. When using bar codes - scanners have to have line of sight to read them. An RFID tag could identify the item (not just its manufacturer and category). Bar codes only provide a manufacturer and product type. They don’t identify unique items. Extremely low error rate. RFID technology is a labor-saving technology. This translates to cost savings. Using bar code technology costs, on average, 7 cents in human labor to scan a bar code. In addition, labor is required to put each label correctly on each plastic crate holder or panel. Add a cost for label changes and replacements for "non readable" codes. And add another for administrative costs for labels that aren't read properly, which causes inventory errors and non-compliant returns and penalties. More about this emerging technology: RFID Our conclusion: Will RFID replace bar codes? Probably not. Bar codes are inexpensive and effective for certain tasks. It is likely that RFID and bar codes will coexist for many years. But RFID is going to be very important. RFID represents an unusual business opportunity. It really is a chance to take operational efficiency to a whole new level.
