Another possibility would be to open an EUR account with a German bank, just across the border. Look for a Sparkasse or Deutsche Bank or Postbank...

The total costs of payments will be around 1%, but ask before opening the account. The yearly fee would quite low, too, if any.
Much less expensive compared to Switzerland where you pay at least 4-5% percent in tax.

In Switzerland, there is postfinance (0.9% processing cost plus around 3% exchange rate plus yearly fee of about 50-100CHF). There are another credit cards which are "free". It means there is no yearly tax, but usually it's a ripoff trying to pay in a non-CHF currency. That's why I highly recommend a German bank.
