You can buy the group transport ticket or the Munich card which is valid for a number of days. This will give you unlimited use of all public transport as well as discounted admission or gifts on some attractions. We used it from the airport for 5 days and it gave us discounts off some attractions as well as a free gift from the Hard Rock Cafe.

Hi - I don’t think I can add anything to the replies you’ve already had but the ticket machines are relatively easy to navigate. It’s a great tram service, easy to use, very efficient and clean. Enjoy your time in Munich, it’s a fantastic city.

Three great ways to travel; U-bahn (Underground railway), trams and buses. The U-bahn will be your fastest. Try the tram when you've got the hang of Munich. The people at your hotel will show you how to do it and the Tourist Office is at Marienplatz for extra maps etc. They make English language announcements on the U-bahn. Easy than it looks, don't worry.

Suivez les flèches vertes y prenez S1 ou S8 jusqu'à station de métro Hauptbahnhof Central.

Lo cierto es que está todo muy bien identificado. Desde que llegamos al aeropuerto hasta nuestro regreso no nos perdimos ni una sola vez. En todas las paradas de metro de bus o de tren dispones de paneles que te ayudan en todo momento, y a parte una vez en el trayecto también te informan de por donde te encuentras.

Hah! It goes to show how much I pay attention. I just looked at my monthly pass. There is indeed a QR code on the tickets. You do not need to scan them anywhere. Perhaps they are for inspectors to scan for validity? As long as you have your ticket that shows a date you will be fine. If and when you buy individual or day time passes or any kind of passes that do not have a date range you do need to validate the ticket the first time it is used at the little blue stamp boxes at the entrance of all public transit. But once it is validated that you do not need to stamp it again.

You can download MVV app and buy it from your phone.
