> Recover from a PDF with QR codes with a barcode scanner

Barcode scanners scan bar codes, not QR codes.

QR codes are commonly considered a type of barcode. cf wikipedia: "A QR code, quick-response code, is a type of two-dimensional matrix barcode"

Many barcode scanners these days can scan QR codes. I have a NetumScan NSL5 that I got for €30 or so that can handle QR, DataMatrix, and even Aztec codes.
