I'd appreciate any opinions/info available on whether a rumor I heard is true or not.
I just learned that US bills, $20 and above, have a magnetic strip embedded in the bill, on the left hand side. Looking at the front of the bill, under the "U" in United States, it's clearly visible on those bill printed in 1990 and thereafter.
You didn't look very closely. Shine a light through the bill, and you will be able to read on the strip the words "TWENTY USA" on the strip in question. It isn't to my knowledge magnetic -- just non-xeroxable. There is also a second security feature -- look closely at the third ring around Andrew Jackson, and you will see that it is not a ring at all but microprinting reading "The United States of America".
