Control reader integration modules are components of ACFA PSIM software package. They are designed to process information received from readers integrated with the ACFA PSIM software.

Control readers shall be utilized to fill in user database with identifiers (codes, access cards, fingerprints, palm vein patterns). It is impossible to build an ACS based on control readers only.

Also, any reader from the ACS integration modules (see ACS integration modules) or FSA/ACS (see ACFA Systems integration modules) can act as a control reader.
