Want To Know Where Your American Currency Has Been Before It Was In Your Wallet?

If you have any left over currency after your holiday in America this website will track where your American currency has been before you had it.
It will track $1, $2, $5, 10, $20, $50 and $100 bills. It requires the note serial number, the bill's series and your current Current Zip/Postal Code [UK users will need to use the 'Click Here' link to find the appropriate code for your nearest recognised UK city]
You can annotate your entry with 5 lines of text describing the note's condition, where you came by it etc. Registering with the site alloows you to track the bills you have already entered.
I found a $1 bill at home and tried it. I found that my entry was the first for this note. However here is an example of a 'tracked' note.
