Client peripheral configuration

Table 128 Peripheral configuration views

Windows client	Figure 499 Peripheral configuration view of Windows standard client
Android client	Figure 500 Peripheral configuration view of Android standard client

1. Authentication mode

   Available authentication modes are,

   1. Identification

      Identification is the default authentication mode. Identification is performed on biometric and user id data. User biometric data such as face, finger print and iris are comparing against the database with previously collected biometric samples depending on the Recognition threshold . If the matching score is greater than the Recognition threshold , user is considered as identified. Therefore, this mode may demand large processing time. User id data such as user id, barcode and QR code are comparing against the database and giving the matching users.

   2. Verification

      The verification mode can be applied with a user id peripheral and a biometric peripheral in order to verify the user against the previously collected biometric sample. To get verified, matching score should be greater than Verification threshold .

      

      Figure 501 Combinations of user id peripheral with biometric peripheral in verification mode

   3. None

2. Capture id first

   The verification sequence when the verification is selected as the authentication mode. If the capture Id first has enabled, id input should be input before the biometric. Otherwise biometric should be given at first.

3. Events

   Attendances will be recorded in the specific event type as selected from this option.
