What is the advantage of RFID over bar codes?
The largest difference between RFID and bar code technology is that bar codes are dependent on line-of-sight technology, while RFIDs are not. In other words, the bar code scanner has to directly “see”the bar code in order to read it, while RFID can be read at any angle, through packaging and even through shipping containers as long as the tag is within the distance range of a reader. RFID tags are also very durable as they can be encased in rigid, protective materials, while bar codes are susceptible to being torn, soiled, or otherwise damaged to a point of being unreadable.
