We’ll be using the Berner Oberland pass. I see we can buy in advance and print at home. Do we have to carry the paper pass around, or is there a QR code/barcode we can take a picture of and scan when getting on trains/buses?
Also, can one person buy all the passes for the group and then forward the tickets/codes to the other travelers? Is there an advantage to buying in advance? We are arriving by car to Lauterbrunnen, where I assume we can purchase the passes at the train station.
