What is the purpose of the AQ transaction?

The purpose of the AQ transaction is to request CHRI (Criminal History Record Information) that is not readily accessible through standard queries. This is particularly important for law enforcement and agencies needing detailed background checks for various reasons, such as employment screenings, investigations, or judicial processes.

AQ transactions are designed to facilitate access to critical information that may not be included in typical databases or that require special permissions to retrieve. This process ensures that authorized entities can efficiently obtain necessary information while adhering to legal and regulatory requirements surrounding the privacy and security of criminal records.

In contrast, other options do not align with the specific function of the AQ transaction. For example, canceling messages, initiating vehicle registration, or updating user information pertains to different transactions within the system and serve distinct purposes unrelated to the retrieval of CHRI information.
