RFID Tags are often called "Intelegent Bar Codes"


Bar Code / UPC Labels



-       Reads one tag at a time

-       Line of sight required

-       Action required by scanner operator

-       Reads multiple tags simultaneously

-       No line of sight required

-       Action not required by operator but does accommodate of demand identification with a handeld RFID reader


Paper labels are easily damaged or obscured by oil and/or dirt

RFID tags can be matched to the application needs, providing the right level or durability for specific environments – from durable flexible labels for use in warehouses to hard-ended, encased RFID tags for fiels use

Data Capacity

Limited amount of data capacity

Significantly greater data capacity, enabling the capture and storage of more detailed and relevant information


-       Static information – write once to any given label

-       Tags are not reusable

Dynamic information – ongoing read/write capability enables creation of a continual record


Information usually printes right on the label along with the bar code (i.e. EPC Code)

Information encoded in RFID chips


Bar codes can only identify a class of goods

RFID tags and their associated serial identification number provide unique serialization
