They speak of "QR-style" barcodes, but it's very unclear to me whether GS1 is actively pushing QR or DataMatrix as the preferred 2D barcode style. In medical devices and pharmaceuticals, both the 1D and 2D DataMatrix GS1 barcodes have been used extensively for quite some time so I would personally think DataMatrix is the way to go. I'm just a casual observer though. Is there anybody here that has more inside knowledge on what the game plan is?
