Credsticks, what do they really look like, Makin' some propz Options

[DamHawke]

I'm in need of a bit of assistance in prepping some necessary junk (folders, plans, the odd severed hand) for my next 'run and was in the midst of getting things ready when I realized I don't really know what a credstick is supposed to look like.

Generally I understand a credstick supposedly looks like a slim USB drive with a display on it (as of SR 4) , but it's also described as a pen-sized tube with data on it as well. For the life of me I haven't been able to find concrete (official) image evidence of what exactly one would look like so, does anyone do? I literally need to make a fistful of credsticks (IMG:style_emoticons/default/nyahnyah.gif)

On a side note: I came up with an idea for my players to use that involves them having a little ID card on the table during gametime so it's easier to remember which Fake ID they're currently using, because everyone at my table has a minimum of three and it gets confusing (plus it prevents cheating). Does it sound like something worth implementing?

Thanks in advance!
