An alternative to the UBS cards is the
PostFinance Visa Gold, which is free if you charge at least CHF 6'000 per year. Other incentives include a 0.75% cash back on purchases (1.5% in the first year) and a 0.9% fee on foreign currency charges (versus 2.5% at some other institutions). I had a UBS card for a few years and found their KeyClub bonus program rather useless.
