RFID vs. Barcodes

RFID vs. Barcodes

While RFID will probably never completely replace barcodes, it has distinct advantages over the barcode. For example,

  • Human intervention is required to scan a barcode, whereas in most applications an RFID tag can be detected "hands off."
  • Barcodes must be visible on the outside of product packaging. RFID tags can be placed inside the packaging or even in the product itself.
  • You must have "line of sight" to read a barcode. RFID tagged items can be read even if they are behind other items.
  • The readability of barcodes can be impaired by dirt, moisture, abrasion, or packaging contours. RFID tags are not affected by those conditions.
  • RFID tags have a longer read range than barcodes.
  • RFID tags have read/write memory capability; barcodes do not.
  • More data can be stored in an RFID tag than can be stored on a barcode.
