Do regular barcode scanners work with QR?

An OMR scanner with hardware works in the following way:

• The scanner emits light onto the form
• It recognizes the variation of the light’s reflectance at specific positions on the form and identifies the black marks as they reflect less light than blank spaces
• The scanner’s computer software then recognizes the marks and converts the scanned images into computer-readable data
• Reports with graphical and statistical representations are automatically generated by the software.

Barcode scanners use Laser lights to scan barcodes and get information from them.

The major difference between rf scanners and barcode scanners is how they operate. Barcode scanners use lasers to scan barcodes that are black and white in color. RF scanners use radio frequency to detect tags and then get information.

Supermarket barcode scanners do not require AI because there is no autonomous activity in scanning barcodes. Barcode scanners used in supermarkets are mostly laser or image-based scanners that only have to read the barcode correctly.

Barcode scanners do not use Wi-Fi. For connecting to the computer, they might use a keyboard or serial ports for wired connection or Bluetooth for wireless connection. For scanning the code, these scanners use light and convert light energy to electrical energy which further is converted into data.
