RFID VS Barcode


What is RFID?

RFID stands for Radio Frequency Identification, a form of wireless communication that uses radio waves to read and capture information stored on a tag for people or object identification.  In simple words, RFID digitalized the concept of barcoding to allow

RFID significantly enhances the quantity of information flow by overcoming the limitations of traditional manual data-collection methods. It can be used as a complementary application or a replacement to the barcode system. Since radio waves are penetrable through cartons and packaging, multiple data-retrieval can be achieved even when none of the tags are within sight. RFID tags can often survive harsh environments such as extreme temperatures, high moisture levels, and rough physical handling which often destroy barcode labels.


The following table show the comparison between Bar Code and RIFD.

  •  Facilitates out-of-sight data read

  •  Cannot be photocopied

  •  works on round surface

  •  more automated, less human intervention

  •  multiple-object identification

  •  carries much more data

  •  Jewelries, watches and other luxuries

  •  Company assets, documents and personnel

  •  Apparel, luggage, cars

  •  People, livestock, pets

  •  Cartons, pallets
