RFID vs. Barcode

 

 RFID

 Barcode

 Line of Site

 Not required (in most cases)

 Required

 Read Range

 Passive UHF RFID:

  • Up to 40 feet (fixed readers)

  • Up to 20 feet (handheld readers)

 Active RFID:  ( battery on board)

  • Up to 100's of feet or more

 Several inches up to several feet

 Read Rate

 10's, 100's or 1000's simultaneously

 One at a time

 Identification

 Can uniquely identify each
 item/asset tagged.

 Most barcodes only identify the type of
 item (UPC Code) but not uniquely.

Read/Write

 Many RFID tags are Read/Write.

 Read only

 Technology

 RF (Radio Frequency)

 Optical (Laser)

 Interference

 Some RFID frequencies do not react
 well with Metal and Liquids. They
 can interfere with some RF
 Frequencies.

 Obstructed and damaged barcodes
 cannot be read (dirt, tears, fading).

 Automation

 Most "fixed" readers don't require
 human involvement to collect data
 (automated).

 Most barcode scanners require a human
 to operate (labor intensive).
