Hi Clint. Switzerland has since the last 2 or 3 years (I guess) been using something similar to the US credit reports. However, unlike the US credit reports, they are used here more to see that you do not have any negative credit information, as opposed to looking for a long credit history in order to trust you. Not having a job here is not a detriment but you do need to show you have some source of income. When I moved here five years ago from the States I applied for a gold credit card for which you are required to have a minimum income of 100,000 francs a year. Although I supplied my 1040 in which it showed my net income surpassed that amount, I was still asked to put a 15,000 to 20,000 deposit guarantee. But, if you do not feel like locking in that amount of money in a savings account, you can always get a Visa or Mastercard with a 5,000 CHF limit pretty easily from Cornèr Banc (
www.cornercard.ch). Unfortunately, their site is only in German or French.
As far as buying a card, you are normally asked about your employment in order to be extended some sort of financing. So, as long as you have a job here, you will be fine.
