HOW TO – Track (and document) currency


Remember when your momma used to tell you: “Wash your hands after touching that money. You don’t know where it’s been!” Well, now you can reply: “I do so! Let’s see: it first showed up in Dayton, Ohio, five years ago, at a Sonic drive-thru, then it headed south, then west, spending a lot of time being handed around amongst Texans. It was even found on the floor of a Dallas strip joint!”

Okay, maybe momma was right. Go wash your damn hands!

This is an excerpt from an item I posted on my site, Street Tech, a few weeks back, about a currency tracking site I’d discovered after seeing a rubber stamp on a dollar that said: “Track this bill at” It was on a bill I was about to feed into a DC Metro FareCard machine. This morning, standing at the same FareCard machines, I discovered another dollar in my wallet with a different “Where is George?” stamp on it. Someone in DC is having fun augmenting money.
