Good to know. This is my first card and I have not received my first bill yet. I know my balance because I only have one purchase. Once I get the slip, can I then use the payment number to pay towards it anytime I want? I am anal and I like to pay off the balance ASAP. Normally I am very anti credit card, but neither of my banks (Post Finance or Credit Suisse) have Visa Debt Cards, so I have to use the credit cards for purchases outside of CH.
