Hi Yelverdack,
thanks for signing up to my website.
I mark every bill with a computer printer. Its actually a Canon IP 1600, perfect for printing bills.
I print a message (
http://www.TrackDollar.com please track this bill online) and a symbol... I use the american flag, that is what will make people look at the bill a little bit closer.
Check FAQ and Downloads on my site, you can download the file to print your $ bills. It is not illegal in US to write on a bill as long as you dont print on the seals etc, the bill should not be unfit for circulation. Thats all.
Here in US nearly every currency tracker stamps their bill, you can design your own rubber stamp, upload it to a website and buy there your own stamp.
A hit rate from about 20% is normal when you mark the bill, 2 bills out of 10 entered will get a hit within the first year.
A lot of tracker here also just write the website name on the border of the bill.
here, this is how i mark my bills:
