I went to a conference recently where, at check-in, we got a little pouch with a neck lanyard to hold our "Hello, my name is..." card. It is perfectly sized to hold my driver's license, health insurance card, credit card, $10 (I rarely have a $20 on me! ), and cell phone. It fits in my jersey pocket and goes into my pocket book when I'm done riding...so I don't walk into a store and realize I forgot everything!
