CRAT smart keys are digital or electronic versions of traditional physical keys used for access control and authorization. These keys take the form of encryption codes, digital credentials and wireless signals that can be transmitted and received by electronic devices such as smartphones, key fobs or access control systems.
Software
Implementing a blacklist in the management system for lost smart keys is a common security measure to prevent unauthorized access. When a smart key is lost or stolen, adding its unique identifier to a blacklist prevents it from being used to access the associated assets. The blacklist prevents the lost key from being recognized and allows only authorized keys to operate.
CRAT Smart locks use wireless communication technologies to provide remote access and control. The encryption and secure protocols are implemented to protect the communication and prevent unauthorized access.
Application
CRAT smart passive locks are used in various settings where convenient and secure access control is needed. Such as power industry, commercial buildings, hospitality, educational institutions, industrial and manufacturing facilities. The application of smart passive locks aims to provide convenient and secure access control without requiring active manual operation. These locks can offer increased convenience, security, and flexibility at very low cost.
