XSCTRL is a smart cloud-based mobile access control system that provides authentication and customer identification within 30 seconds. XSCTRL is designed to support multiple users at one time, all via the users mobile phone. The system can confirm entry and exit at the gate control by receiving a QR code generated by the application or working with an NFC reader or virtual keys. Customer authentication by face recognition is an integral part of the XSCTRL system, which is secure and cannot be copied or reproduced. The system can require a digital signature on health declarations or any other documents before entry is allowed on the complex, and one-time password integration for work is guaranteed in internal corporate computers.
