Needless to say, this process was expensive and time-consuming, so stores didn’t do this more than once per month.

How the use of barcodes can lead to increased business in a supermarket?

Which is better barcode or RFID?

Surpasses Barcodes Limitations RFID avoids the limitations of barcode scanning, which requires line-of-sight access to each barcode and can only be used to scan one item at a time. Instead, RFID tags do not require line-of-site, and multiple RFID tags can be detected and read remotely and simultaneously.

Not all barcode scanners can read all barcodes. Laser barcode scanners and linear imagers read only 1D barcode scanners. Imager (camera-based) 2D barcode scanners read all common 1D and 2D barcodes.

What is the difference between QR codes barcodes and RFID?

If barcodes are in a sense one-dimensional data, and QR codes are two-dimensional, than you can think of RFID tags as a three-dimensional code. Instead of laser scanners for barcodes and optical scanners for QR codes, RFID tags use radio waves to transmit the information stored in them.
