What is bank bait money?

Bank bait money, also known as marked money or tracer money, is currency that has been specifically marked or designated for the purpose of tracking it in the event of a robbery or theft. The money is distributed throughout a bank's cash drawers and vaults in a hidden or inconspicuous manner, and is designed to function as a decoy for potential robbers. The goal is to make it easy to identify and track stolen money, leading to the arrest and conviction of the criminal. The use of bait money is a common practice among law enforcement agencies and financial institutions as a way to deter robberies and improve the chances of apprehending the culprits.
