The opening title sequence is created by the duo Olivier Kuntzel + Florence Deygas. The "stamp style animation" lasts roughly 2 minutes 30 seconds and features silhouettes of the main characters acting out the plot of the film, even down to the smallest details.

Carl Hanratty: Our unknown subject is a paperhander who started working on the East Coast. In the last few weeks this unsub has developed a new form of check fraud which I'm calling "the float".

MICR scanners at every bank read these numbers at the bottom of the check - slide - and they ship that check off to its corresponding branch.
