2D Barcode - Is 2D barcode same as QR code?

While 2D barcodes and QR codes may appear similar due to their square or rectangular shape, they are not the same. QR codes are characterized by distinctive corner squares while 2D barcodes have a more uniform appearance. QR codes can store more data and can be scanned using a smartphone, unlike 2D barcodes which require specific scanners. This makes QR codes a more versatile choice for a variety of applications.
