Which transaction type is part of CHRI transactions available across NLETS?

The transaction type that is part of CHRI (Criminal History Record Information) transactions available across NLETS (National Law Enforcement Telecommunications System) is FQ. CHRI transactions are critical for law enforcement agencies to access criminal history information and facilitate background checks.

FQ specifically refers to a "fingerprint query" which allows agencies to submit a request for a biometric comparison against the national database for criminal history records. This type of transaction is essential in law enforcement for identifying individuals based on their fingerprints, ensuring accurate criminal identification and verification processes.

Understanding the context of each transaction type can further illuminate why FQ stands out in this case. AP, BR, and MR do not pertain specifically to CHRI transactions in the NLETS system. Thus, the significance of FQ lies in its direct application to criminal history checks and its integral role in law enforcement operations.
