Zurich Airport is a paragon of efficiency; what else can you expect from the Swiss. While suitcases revolve on the carousel, a monitor above updates train schedules for trains departing from the airport. I purchased Swiss Transfer Cards, most economical for our purpose, online through Swiss Travel System. The transfer card allows two transfers by rail between any Swiss airport or border town and any single destination in Switzerland. Each transfer must be completed in one day and most within one month.
I paid and received an online voucher that had to be presented to the Airport Information Service Centre, Parkhaus 2 on the 1st Floor. To find the service desk after collecting luggage in the arrival hall, walk toward the Airport Railway Station and follow the signs to the shopping mall. Take the first pair of escalators up to the next level and the Service Centre desk is on your right. Hand in voucher, personnel will hand over tickets which must be filled in with name, country, passport number and first day of travel and you are set to go
