QR vs. Barcode vs. RFID
• QR Codes, barcodes and RFID are all systems for 
conveying large amounts of data in a small format.  They 
offer speed, labor savings and cost savings, among other 
benefits and there are distinct differences between all the 
three according to the purposes they are best suited for.
QR Code
• QR codes are similar in one sense to bar codes, in that they 
contain information which can be scanned and read by a 
camera-equipped smartphone. You could walk into a place of 
business, see a QR code on an item, scan it with your 
smartphone, and immediately have access to a lot of 
information electronically.
Advantages
• It’s not hard to generate a QR code. You can create one for 
free online. The Google URL shortener automatically creates 
one for a Web page each time a URL is shortened. They have 
infinite uses in small businesses, especially for marketing, now 
that everybody on the planet has a smartphone.
Barcode
• Barcodes are versatile with a large variety of uses, especially 
in retail and manufacturing, in transport and shipping. 
Barcodes have become common in shipping, to enable 
greater accuracy and speed in getting packages delivered. 
Advantages
• Barcodes are used to manage large filing systems, library 
books, and a host of other purposes where large numbers of 
items need to be tracked efficiently. They are relatively 
inexpensive, and help drive speed, efficiency and profitability. 
RFID
•  RFID involves applying RFID tags to items or boxes or 
pallets. The tag with its small antenna emits a radio 
frequency signal that is picked up and read by a special 
wireless RFID reader, conveying information from the tag 
about the item it is affixed to.
Advantages
• RFID is adaptable to many of the same uses that 
barcodes are good for.  But RFID is especially useful in 
situations where vast quantities of goods must be moved 
or tracked, or where tracking of item-specific information 
is necessary.
Significance
• Today, RFID, Barcodes ad QR codes are widely used 
throughout the world. Automatic toll payment at highways 
in India called Fastag works on RFID.
Conclusion
• RFID, barcodes and QR Codes all have their place for 
different purposes and under different circumstances.  As 
with most technology, the cost to acquire and use it keeps 
coming down with each passing year.  All 3 of these data 
management systems also have gotten much easier to 
implement in the past few years.
