Hi all,

First time travelling to Germany tomorrow and I purchased a Munich card. It arrived via a pdf with a barcode on it. Possibly some silly questions but just want to confirm everything so I don't mess up:
1. Do I have to 'stamp' it or activate it in some way?
2. For the first use, can I just get on the train without doing anything to it (like go to a ticket machine)?
2. For buses, Do i just show the pass to the driver?
