What document must be carried by a security guard while on duty?

A valid PERC card must be carried by a security guard while on duty because it serves as proof that the guard is licensed to perform security services in Illinois. The PERC card, which stands for "Permanent Employee Registration Card," is issued by the Illinois Department of Financial and Professional Regulation after the individual has completed the required training and background checks. This card verifies that the security guard has met the necessary qualifications and is legally authorized to perform their job responsibilities.

Having the PERC card on hand is essential not only for the guard’s compliance with state laws but also for building trust and confidence with employers and the public. In situations where the validity of a guard's status may be questioned, presenting the PERC card can help to clarify their authorized role. Other documents, such as a driver's license or criminal record check, may be important for different reasons but are not mandatory to carry while on duty like the PERC card. Likewise, an employment contract is typically a private agreement between the employer and employee and is not something that needs to be shown publicly during the execution of security duties.
