RFID vs Barcode
from Barcodes to RFID
To understand why many industries are now adopting RFID over barcode you need to look at the simple facts:
Barcode patented in 1957 and based on Morse code is a method of representing data in visual form. Initially, bar codes represented data by varying the widths and spacings of parallel lines, now they represent many variants of geometric patterns.
Radio-frequency identification (RFID) refers to a technology whereby digital data is encoded onto RFID tags to electronically store information via radio waves.
RFID vs Barcode
• RFID tags have the potential to contain highly detailed data – Barcodes contain only basic information relating to the product.
• RFID tags can be read without the line of sight – Barcodes require a line of sight in order to be read.
• Multiple RFID tags can be read simultaneously – Barcodes must be scanned individually.
• RFID tags have a read range of up to 300 feet away – Barcode scanners must be within 8 feet of the barcode in order to read the data.
• RFID tags have read/write capabilities. Information can be updated and added – Barcodes are read only, and information cannot be updated or added.
• RFID provides a unique product code for every individual item – Barcodes contain only the type of product or item.
• RFID tags are difficult to replicate, and data can be password protected – Barcodes can be easily counterfeited or replicated.
• RFID tags are highly durable and are not easily damaged or affected by dirt – Barcodes are typically printed on paper or plastic, which makes them easy to damage. A damaged barcode can’t be read by a scanner.
• RFID eliminates human error – Barcodes are subject to human error. A person can accidently scan the same item twice. Equally, the scanner could miss an item.
