RFID is currently being hailed as the next major revolution in Auto-ID. However, there are many misconceptions about its capabilities. Below are the top 5 common misconceptions DataScan come across time and time again.
- RFID tags can be tracked and traced from space via satellite
"Big Brother is watching" - Many people believe that RFID is just another way for organisations to keep track of us. However the reality is very different. Currently the maximum read range of UHF RFID tags is approximately a mere 5 meters and for HF tags (used more commonly) is less than 1 meter.
However, using appropriate equipment with GPRS, it is true that an active tag could be tracked using satellite. It is important to note that the read range of the tag itself does not change.
- RFID is a new technology and has not been tried & tested
"I don't want to be the guinea pig" - Not many people want to be the first to try out a new technology, however RFID is not a new technology. An early version of RFID was first used during the Second World War, to identify which planes are friend or foe.
RFID as we know it today, has been used in businesses since the mid-late 1980s. DataScan have been designing and implementing RFID systems using a variety of frequencies for over 10 years.
- RFID will make barcodes obsolete
"I've invested too much in barcodes, to just scrap it" - RFID is not a replacement for barcodes. Although they can be used in similar applications RFID can work very comfortably side by side with barcodes.
Often RFID comes into its own in applications where barcodes are simply not feasible i.e. extremely harsh environments or where line of sight for scanning is not possible.
- RFID can only be used in the supply chain
"What do I need RFID for?" - The supply chain and retail sectors lend themselves particularly well to RFID, however RFID can be used in a wide range of applications. DataScan have implemented RFID systems that have improved safety of Coke productions through to systems, which improve the efficiency in WIP applications.
- RFID can not be used with metal or water based products
"I store my goods in metal containers, so RFID is no good" - Metal reflects and water absorbs radio waves at Ultra High Frequencies (UHF). However, at other lower frequencies this is not the case. With expert advise and good system design using the correct frequencies, most short-comings can be over come. DataScan have over 10 years experience working with all frequencies and understand the strengths and shortcomings of all the frequencies currently available in the RFID market.
