Got the new cards today (our mail was waiting for us when we arrived). Citibank took over our AT&T account. No changes to the card other than the name and account number. Yes, you can pay online although I don't because I'm never sure we'll have an internet connection when payment time rolls around. I pay EFT via a phone call to my bank. You also can have them auto draft your checking account for the balance due, if you want that option. The info is at
www.citicards.com . Ours is called the "Dividend" Platinum Select MasterCard.
I occasionally check online to see how much I've accumulated. If it's over $50 you can just click the link and tell them to send you a check. I recently deposited a check for $72.45. That's the second or third check this year.
