Mobile check-in takes place via the website of the respective airline. You can find the link in the overview under "Mobile Link". Your boarding card will be sent directly to your mobile phone via SMS/MMS.
Depending on the airline, baggage is either handed over at the normal check-in desk or at the specially designated bag drop for customers who have checked in via the web, which is located in the respective check-in area at Zurich Airport.
If your mobile phone has run out of charge or you have forgotten to bring it with you, you can print out a paper boarding card or have one printed out for you at any time at a check-in machine, at the baggage handover desk or at the check-in desk at the airport.
