It tends to be targeted by overseas syndicates and “money factories” in certain countries. The $100 note is the most frequently counterfeited. To make it even faster, there are only two worth checking: the $100 dollar bill and the $20 bill. There are some notes can you pretty much ignore, and others that should you should check carefully. Here is a tip that can speed up the whole process. Take a close look, especially at the borders, to see if there are any blurred parts in the bill. Laser and inkjet printers are rarely capable of the same level of detail.
Authentic bills are extremely detailed, made using die-cut printing plates that are capable of creating impressively fine lines. If you notice significantly blurry borders, printing, or text, this should be an automatic red flag.
However, this tends to take too much time and is not very effective. You can also place each bill next to a real bill of the same dollar amount and see if something doesn’t match. Nine times out of ten, your fingers will be accurate fake detectors. If it doesn’t feel right, set it aside for further checking. Give each bill a quick rub between your fingers.

So, let’s start with the simplest tests and work upwards.
