Sure. It's an SBB 1/2 Visa card. The commission is equal to 2 chf every time you upload. You can upload up to 3,000 chf at once and it takes roughly 2 working days for the money to be deposited in your account.

I also had them block the card when I purchased on 3 different travel websites in one day for "security purposes". It took just one phone call to resolve the matter and the woman from Jelmoli (that's the company that's actually in a partnership with SBB for these Visa cards) was very friendly and helpful.
