A standalone biometric authorization control device (10) comprises an input device (110) configured to receive a time sensitive authorization code comprising encrypted information about an authorization time schedule. Connected to the input device (110) is a control unit (120), configured to extract the authorization time schedule from the time sensitive authorization code, and to compare the extracted authorization time schedule with the current date and time. Connected to and controlled by the control unit (120) is a biometric sensor (130), which is configured to obtain biometric data from a user. The control unit (120) is further configured to register the biometric data obtained from the user into the current standalone biometric authorization control device (10) if the current date and time is within a time interval when registering of biometric data is allowed according to the extracted authorization time schedule. |
