Currency bill tracking

Have you ever seen paper money, like a dollar bill? It's something you can use to buy things that you want. But did you know that some money has special tracking on it?

People can write down a special number or website on the bill, which can help track where the bill has been and where it goes next. It's like playing a game of hide and seek with your money!

When you get a bill like this, you can go online to the special website and input the tracking number. That way, you can see where the bill has been before it got to you. And once you spend the bill, someone else might find it and start tracking it too.

It's not something you have to do, but it can be a fun way to see how far your money can travel and where it ends up.
