Credit Card sized MP3/Video player

I am looking for an mp3 player or a video player OR both- that is the size of a credit card.

I also have a few other requests for requirements -

When I eBay "credit card size mp3 player"

there is a seller who sells these mp3 players but they have goofy graphics on them.

Also, on youtube there is a card called the edg card but looks like the site is shutdown and you have to order about 25000.

anyway -

I am an artist who works in video and audio and I would like to make a video or audio business card...

does anyone know where i can find these mp3 players like the one on eBay but in a solid card or where I can print my own graphics?

Does anyone know if there is such a video device that I can something like the edg card....(there's also an rcard, but it looks like that never came out either)

if anyone can recommend anything i would greatly appreciate it as I really don't want to have to a...keychain. lol

thanks.

the d2+ is nice but it is pretty thick....

to be more specific, I have found this cheeseball looking company that sells something similar to what I am looking for but I
am not really sure how legit this place is. Wish I could find something here in the states are something a little more - non-rip-off looking...

These are thin enough to carry like a business card...

I've also come across this Evergreen - but looks outdated and can't find anything new. It's pretty weird that the only thing I am coming across are articles and pictures from 2007....and then it just stops!

geez head-fi....thought this was the place to be

well i contacted all the people who sell the actual credit card like cards and no one responded so i don't consider them legit. the m6 is much too thick. yes, i plan on handing them out to certain "clients". more of an art piece. oh well, i'll keep searching.
