Walk In, You've Been Recognized: The Evolution of Identification Technologies in Modern Access Control Systems

PERCo has expanded its PERCo-Web access control system with new BLE-enabled readers, companion mobile apps, and a joint facial recognition solution developed with the CRТ group. The update provides an opportunity to examine how identification methods in physical access control have developed without any single technology fully displacing the others. Traditional proximity and MIFARE cards remain the foundation, while QR codes, NFC, BLE, and biometrics each occupy specific niches based on convenience, security, and regulatory requirements. Russian Federal Law 572-FZ has fundamentally changed facial biometrics deployment by mandating use of the Unified Biometric System (EBS) or accredited commercial systems (KBS) for authentication. The article explains the technical workflow from reader to controller, the cryptographic protections of modern cards, the contactless advantages of BLE, and the privacy and compliance considerations that now make facial recognition a 'technology of trust' rather than simple convenience.
