Question: are 2d barcodes and qr codes the same?
Answer: A lot of sites seem to use the terms “2d barcodes” and “QR Codes” interchangeably, and while QR codes are a type of 2d barcode, not all 2d barcodes are QR codes. Typically, when referring to a non-QR code 2d barcode, I refer to them as “proprietary barcodes.”
