    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.


    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.
