I carry both a yellow leather Coach magnetic money clip, and a red leather Jack Spade card holder.
The clip holds:
state ID/DL (depending on whether I will be driving or not)
The case holds:
Zip car card
any claim tickets (dry cleaner, cobbler...)
Sometimes I travel light and slip the CC in the clip
I previously carried a lot more in a passport style wallet in either my inside breast pocket, or in a messenger bag(if I was not wearing a jacket). One day I was working in the store alone, and someone snuck in the stockroom and took the wallet from my bag. Before the end of my shift they had shopped at a dozen stores, rented a limo, and gone to a strip club. In the end I was not liable for any of the charges, but even still I carried only cash and ID for a while afterwards. I am off the cash economy now, but everything I do not need stays at home.
P.S. I did consider writing checks after seeing those trite Visa check card ads the first time
