What must be written on a check to facilitate prosecution of "bad check" writers?

For the prosecution of "bad check" writers, it is essential to include the driver's license number on the check. Recording this information helps establish the identity of the individual who wrote the check, which is crucial for legal proceedings. It connects the transaction to a specific person and can assist law enforcement and judicial processes in tracing the individual if the check bounces due to insufficient funds or other reasons.

Including a driver's license number not only provides proof of identity but also can serve as a means of identifying a pattern of behavior if an individual has a history of bad checks. Additionally, it enables the potential for follow-up actions to recover the funds or pursue legal recourse.

Other options, such as a credit card number, social security number, or bank account number, do not serve the same purpose in a legal context for prosecuting bad check offenses. They may be relevant for different transactions or situations but do not provide the necessary legal identity verification needed for successful prosecution in cases involving bad checks.
