The Similarities and Difference between RFID, Barcode and QR code

Radio Frequency Identification(RFID), QR Codes, and barcodes are typically systems for conveying massive amounts of data into a small format. They offer speed, labor savings, and cost-effective, among other benefits.

The Similarities between those are:

1. They are all generally technique of data collecting, where data stored on all three types of cards is usually retrieved via either fixed or handheld scanning devices, and, therefore, both are incredibly well-liked as part of the inventory tracking workflow.
2. In addition all RFID cards and barcodes or QR codes can make it happen to suit your needs if you need to track where your stuff is.

The main differences between them are:

1. Barcodes run on the light and sensor to read the information encoded on the card. while RFID uses radio waves, which doesn’t need line of sight, to obtain the data
2. RFID scanners can process dozens of RFID cards within a second, while Barcode/QR code scanners are only able to process tags individually via each scan.
3. RFID is much more secure but the RFID system is more complicated. Barcodes/QR code is straightforward to use as well as easily be replicated or counterfeited.
4. To be protected from the working environment, RFID inlay could be hidden inside the card while Barcode/QR code has to be exposed outside.
5. Finally, the cost difference between barcode/QR code card and RFID card is quite extensive, where the RFID card is substantially cost higher. However, the pricing gap is getting more close as RFID has been widely used in many industries in recent years, their price goes down every year.

RFID, barcodes and QR Codes all have their target market for different purposes under different working circumstances. As Radio Frequency Identification (RFID) technology became more essential to the Internet of things (IoT), the potential market for RFID card or labels are enormous.
