Can barcode scanners read QR codes?
QR codes are best read by 2D barcode scanners. These codes cannot be read by standard or 1D barcode scanners. The 2D scanner will take a picture of the entire image of the barcode at once. This data is then analysed by a decoding algorithm to define the information contained in the code.

But no matter how much they contain, when scanned, the QR code should allow the user to access information instantly – hence why it’s called a Quick Response code.
Can a 2D scanner read a QR code?
1D codes, such as the UPC code, are usually variable-width black and white spaces. 2D codes, such as QR codes and Data Matrix, use squares, hexagons, and other shapes to store data. Imager (camera-based) 2D barcode scanners read all common 1D and 2D barcodes.
Which is better barcode or QR code?
QR codes can hold more information – While a barcode can represent up to 25 characters, a QR code can go up to 2500. So you can print smaller labels that carry more information. QR codes are easier to read – to read a barcode you have to aim the scanner in line with the code, while a QR code can be read from any angle.
