Detailed explanation-1: -Barcodes encode product information into bars and alphanumeric characters, making it much faster and easier to ring up items at a store or track inventory in a warehouse. Besides ease and speed, bar codes’ major business benefits include accuracy, inventory control and cost savings.

Detailed explanation-2: -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.

Detailed explanation-3: -A barcode reader works by directing a beam of light across the barcode and measuring the amount and pattern of the light that is reflected. The scanner converts the light energy into electrical energy, which is then converted into data by the decoder and forwarded to a computer.
