I'd like something thin that holds:

My Driver's License
My Medical (Insurance) Card
My Credit Card
My House Key
Some Cash

It should be possible to get it into a wallet as well when I don't have it stashed in my bike-pouch.

If it could open bottles and envelopes, and perhaps had an led light as well that would be awesome but these are all optional requests.

Anyone have any suggestions?

Or...

Does anyone have any alternatives? My goal is simply to have enough room in my tiny-under-the-seat pouch to hold my spare tube, tire-pryers, patch kit, cell-phone (Nokia 6615i, about 4" by 2" by 1/2"), and then the items I mentioned above that I need a holder for.

I've googled for a credit card holder dealy but all I found were money clips, I'd like something I can actually slide cards into. Also it would be nice if it were transparent so the Driver's License could be seen through it. I've been using a rubber band tied around all that stuff but its cumbersome to get anything out and then put it back.

Thanks!
