I made slightly reduced size photo copies of my license, medical insurance card, blood bank membership card and laminated them. They can be used to identify me but obviously aren't official if lost. These and $20 - $40 go into a 3x5 zippered REI bag and into my jersey pocket. Phone in a zip lock bag goes into another jersey pocket. If I'm not wearing a bike jersey, all go into a fanny pack. I also wear a Road ID 24/7 with contact info and some medical information.
