RFID VS BARCODES: Advantages and disadvantages comparison.

Filed under: Technology

While manufacturers currently employ two forms of automated data collection: barcodes and RFID systems; there is much hype as to whether RFID will end up taking over the barcode.  One data collection method is not essentially better than the other; they do both carry product information however both differ a great amount.




BarcodesRFID (Radio-Frequency Identification)
What is it?basic Barcode

A barcode is a visual representation of data that is scanned and interpreted for information. Each barcode contains a certain code which works as a tracking technology for products; and is represented in a sequence of lines or other shapes. Initially this technology was symbolized by the width and spaces between parallel lines that were one dimensional. This then evolved into other geometrical shapes such as rectangles and hexagons that were two dimensional. This barcode technology can be scanned by barcode readers along with newer technology on devices such as smartphones and desktop printers
RFID Scanning Wristband

Radio Frequency-Identification technology (RFID) involves a tag affixed to a product which identifies and tracks the product via radio waves.  These tags can carry up to 2,000 bytes of data. This technology has three parts: a scanning antenna, a transceiver with a decoder to interpret the data and a transponder (RFID tag) pre-set with information. The scanning antenna sends out a radio-frequency signal providing a means of communication with the RFID tag.  When the RFID tag passes through the frequency field of the scanning antenna; it detects the activation signal and can transfer the information data in holds to be picked up by the scanning antenna.
  • Much smaller and lighter than RFID tags and therefore easier to use.
  • Less expensive than RFID tags; as barcodes are directly printed onto plastic or paper materials and therefore the only cost involved is the ink; a tiny overall cost.
  • Barcodes work with the same accuracy on various materials in which they are placed.
  • Barcodes are a universal technology in that they are the norm for retail products; stores that own a barcode reader can process barcodes from anywhere in the world.
  • In many cases; barcode accuracy has been said to be the same or even better than RFID tags.
  • Today barcodes are found on almost every item and there are no privacy issues involved with its use.
  • Can read RFID tags from a greater distance than barcodes.
  • RFID tags don’t need to be positioned in a line of sight with the scanner.
  • RFID tags can be read at a faster rate than barcodes; as approximately 40 RFID tags can be read at the same time.
  • RFID tags can work within much greater distances; information can be read from a tag at up to 300 ft.
  • RFID tags are read/write devices.
  • RFID contain high levels of security; data can be encrypted, password protected or set to include a ‘kill’ feature to remove data permanently.
  • RFID tags carry large data capabilities such as product maintenance, shipping histories and expiry dates; which can all be programmed to the tag.
  • Once these are set up; it can be run with minimal human participation.
  • RFID tags are more reusable and rugged as they are protected by a plastic cover.
  • Barcode scanners need a direct line of sight to the barcode to be able to read.
  • In order to read the barcode, the barcode scanner needs to be quite close; around no more than 15ft.
  • Barcodes have no read/write capabilities; they do not contain any added information such as expiry date etc.  They only contain the manufacturer and product.
  • They are very labour intensive; as they must be scanned individually.
  • Barcodes have less security than RFID; as they can be more easily reproduced or forged.
  • Barcodes are more easily damaged; as the line of sight is needed to scan, the printed bar code has to be exposed on the outside of the product.
  • If a barcode is ripped or damaged there is no way to scan the product.
  • RFID involves assembling and inserting a computerized chip; which works out to be more expensive.
  • RFID readers struggle picking up information when passing through metal or liquid.
  • Reader collision can occur where two signals from different readers overlap and the tag is unable to respond to both.
  • Tag collision can occur when numerous tags in the same area respond at the same time.
  • RFID still has two separate chips (read only and readable/writable), which cannot be read by the same machine.

From this comparison we can see that both forms of automated data collection have their advantages and disadvantages; and one may be preferable to suit your specific needs; however one can’t be said to be more superior than the other.  Will barcodes slowly be replaced with RFID technology in today’s supply chain? What do you think?

An excellent unbiased comparison of RFID and barcode tagging technologies. Can I have your permission to copy and distribute this comparison within my company, we are trying to make a decision on what technology to go with?

I am very happy to meet it this helps me a lot with my research staff. It is better than in the other sites with RFID’s ideas.
Thanks a lot.
Take care smile

RFID is a great techonlogy with ton of features still to process. Unfortunately needs a great investment on time, money and development. Maybe in the future but for sure, barcodes will still rule during… mayb the next 10 or 20 year…

Thanks! This helped me in my Software Design and Development Prelims. Great comparison.

very nice information!  i have one question, for automatic billing in super market whether barcode reader is better or RFID? my requirement is as soon as product is kept in cart, it should be scanned and if it is removed its amount should be removed.

Hello, i am working on a thesis about comparing both technologies, do you ming if i quote you on it? thanks!

I think RFID will be the furture.RFID technology is more widely used.

Thank you for these insights !
In general   shopping websites provide sometimes truncated results, so you should
inform yourself on how it works before using them.I’d like sharing with you another point of view about these platforms.
It was worth reading it:

        I have gone through the article, where the author has beautifully made a comparison between barcode& RFID, earlier I was very confuse now it is clear to me, can u permit me to take some technical portion of this article for reproduce in our supply chain magazine in India for the benefit of our members I am a research scholar doing phd.

Hi Carrie,

Not a problem to use us as a source.

As long as we are referenced that is fine.

I always thought that barcode couldn’t be scanned if the tags were damaged but after reading through your blog, I understand that the scanner can read through torn tags.

So do you think barcoding is better compared to RFID cause RFID transmits data and signals? So maybe an improvised version of barcoding could overcome the flaws of RFID you think?

Nice comparison between RFID and Barcodes.
Beacons came into picture due to this disadvantages of RFID and Barcodes.

in my point of view i think barb is very essential for tracking things. through this device any industry can manage their product in proper and without error. and if there is any technical issue with it you may contact on
