hsbc has the weekender card which offers 1% M-F and 2% on Saturday and Sunday. The limits are not as low as what is often encountered on the household 2% cashback card (limits easily go into the $20,000 or higher range). Also, the weekender card has no monthly/annual cashback limits (unlike many cashback programs).

NASA FCU has a card that pays 2% cashback after the first $2000 of spending each month and 1-2% for the first $2000; again with no monthly or annual caps.

PEDFED FCU also has a good cashback card although I don't have the details in front of me.
