Abstract
A biometric information sensor device includes a control unit that issues a notification for failure to read biometric information of a detection target when reading of the biometric information fails after a contact of the detection target with a reading surface is detected.
Claims10
A biometric information sensor device, comprising:
- a controller that issues a first notification for failure to read biometric information of a detection target when reading of the biometric information fails after a contact of the detection target with a reading surface is detected,
- wherein, when a number of failures to read biometric information is not less than a predetermined number after the contact with the reading surface is detected, the controller determines that a conductive foreign matter is sticking to the reading surface, and issues a second notification about the conductive foreign matter,
- wherein the controller issues the first notification when the number of failures to read biometric information is less than the predetermined number, and issues the second notification instead of the first notification when the number of failures to read biometric information becomes not less than the predetermined number, and
- wherein the predetermined number is equal to or greater than two.
