    Before You Enroll an Employee Fingerprint

    Employees should only be enrolled once the clock has been installed and mounted against the wall (at about shoulder height for the average person). 

    It is a good idea to keep a cloth handy during the enrollment process to clean or dry employee fingers and to clean the scanner surface if necessary.

    Before starting the enrollment process, please check the following:

    • The employee’s hands must be clean. This will ensure the best possible fingerprint capture.  Dusty, greasy or dirty hands must not be enrolled.
    • The employee’s hands should not be wet or sweaty. If there is too much moisture on the skin it will fill up the valleys between the ridges of the fingerprint to create an even surface which the scanner may see as a black blob.  Use a cloth to clean and dry the fingers if these symptoms are experienced.
    • The employee’s hands should not be overly dry.  This may be a problem especially during the winter time.  A finger with very little moisture will hardly be noticeable on the scanner surface.  Rubbing the finger on the forehead or behind the ears will add bodily oils and some moisture to the skin.
    • The employee’s finger should not have any cuts or any physical damage that will heal.  If the employee’s profession is such that some damage may occur to the fingers, try and select a finger that is less likely to be damaged.

    Finger Positioning

    The correct positioning of the finger on the reader is essential during enrollment as well as when the employee is clocking.

    1. Placement:  As shown in the pictures below, the CS TimeClock has a ridge below to scanner as a placement guide.  The employee must place the crease in their finger on the ridge when enrolling or clocking.

    2. Inclination and rotation:  The finger must be placed flat on the reader with the crease touching the ridge below the scanner and the core of the finger touching the scanner surface.  A finger that is lifted from the scanner or rotated with only the side of the finger touching the scanner will result in a partial scan of the finger.

    3. Pressure:  Applying too much or too little pressure can have adverse effects on the quality of the overall enrollment quality.  Too much pressure will cause the ridges and valleys to contract as the skin flexes.  Too little pressure may result in a partial scan of the finger.  The employee must place their finger firmly on the scanner when enrolling as to leave a proper imprint.

    The correct positioning of the finger on the reader is essential during enrollment as well as when the employee is clocking.

    1. Placement:  To ensure the same placement the finger must be placed against the back of the cover, even if the crease of the finger joint is on the reader.

    2. Inclination and rotation:  The finger must be placed flat on the reader.  A finger that is lifted from the scanner or rotated with only the side of the finger touching the scanner will result in a partial scan of the finger.

    The Enrollment Procedure

    An employee’s fingerprint is enrolled against a card number.  This card number can be a proximity card or a PIN number and must be a unique number for each employee.  During the enrollment process the employee would need to place their finger on the reader three times at different angles to create their fingerprint template.  It is advisable to demonstrate to the employee how to place their finger on the reader before enrollment.

    Troubleshooting

    Before starting to troubleshoot, please ensure that your clock is on the latest firmware release.  Please contact your supplier if you have any questions or if you require assistance to update your clock.

     “No Fingerprint Match” is displayed when an employee clocks.

    The reader is unable to match the employee fingerprint to one in its database. 

    1. Please check if the employee places their finger correctly on the reader.
    2. Re-enroll the same finger or enroll a different finger. Use the Slow enroll type.  The sequence will take a few seconds longer, but you will get a fingerprint quality value at the end of the enroll.  If the quality is below 60%, enroll a different finger.
    3. Drop the fingerprint security level in the CS TimeClock web interface or in your TNA software.  
    4. Use fingerprint verification i.e. the employee must enter a PIN or swipe a card before placing their finger.  This will increase the chance of a positive match as it would only have to match the employee fingerprint to one template in its database. You can change the setting in the CS TimeClock web interface (Cards or Pins, Reader Required) or in your TNA software.
    5. If the employee still struggles to clock, try changing the verification options in point 4 above.

    Card not assigned” is displayed when an employee clocks.

    The finger is matched to a template on a card which is not assigned to an employee.

    1. A card number will be displayed when the employee clocks.  If the card number displayed is correct, check that the card is assigned to the employee in the TNA software or in the CS TimeClock web interface.
    2. If a different card number is displayed on the clock it is possible that the employee’s finger was previously enrolled on a different card number that is no longer in use.  Force a refresh of the templates on the reader from the web interface:  go to the Hardware menu, select Child Clocks, select and change the child clock, select Force Full FP Reader Refresh and click on Save.

    Unknown Card” is displayed when an employee clocks.

    The finger is matched to a template on a card which does not exist in the clock database.

    1. A card number will be displayed when the employee clocks.  If the card number displayed is correct, add the card in the TNA software or in the clock web interface and assign it to the employee.  If not, force a refresh of the reader: go to the Hardware menu, select Child Clocks, select and change the child clock, select Force Full FP Reader Refresh and click on Save.

    “Unknown employee”is displayed when an employee clocks.

    The clock does not recognize the employee number to which the card is assigned.

    1. This problem may occur when using versions of TNA software which is not case sensitive with alphanumeric employee numbers.  Please ensure that alphanumeric employee numbers are all in upper case.

    Another employee’s name is displayed when the employee clocks.

    The reader has matched the employee finger to another template in the reader database (a false positive).  

    1. Increase the fingerprint security level for the employee who clocked as well as the employee whose name displayed on the clock.  At a low fingerprint security level the reader will use less identification points (minutia) to match a finger to a template and it is therefore possible that the same minutia may occur in more than one fingerprint template.  See the CS TimeClock Web Interface Manual, Changing a Card or PIN number:  Fingerprint Security Level.
    2. Use fingerprint verification i.e. the employee must enter a PIN or swipe a card before placing their finger.  This will increase the chance of a positive match as it would only have to match the employee fingerprint to one template in its database. See the CS TimeClock Web Interface Manual, Changing a Card or PIN number:  Reader Required.

    No response to any employee fingers placed on the reader.

    1. Check that the fingerprint reader is enabled and set to the correct reader type in the TNA software or web interface. 
      Futronics Readers:
      Go to the Hardware menu in the clock web interface, select Child Clocks, select and change the child clock and click on the Fingerprint tab.  The reader must be Enabled and the Type set to FS83 Identify or to FS83 Verify.  If it is necessary to change any of these settings, Save the changes and reboot the clock from the clock keypad menu (#, 9, 1).
      Lumidigm Readers:
      Go to the Hardware menu in the clock web interface, select Child Clocks, select and change the child clock and click on the Fingerprint tab.  The reader must be Enabled and the Type set to Lumidigm Identify Only, Lumidigm Verify Only or to Lumidigm Verify (Extended).  If it is necessary to change any of these settings, Save the changes and reboot the clock from the clock keypad menu (#, 9, 1).
    2. Lumidigm reader:  The fingerprint reader’s database is empty.  If there are no fingerprints enrolled the reader will not scan for fingers.  If there are fingerprint templates in the software database, force a refresh of the templates on the reader from the web interface:  go to the Hardware menu, select Child Clocks, select and change the child clock, select Force Full FP Reader Refresh and click on Save.
    3. There is a hardware problem.  Please contact your supplier.
       

    The reader does not respond to some employees fingerprints.

    In certain professions it is possible that the employee’s fingerprints have eroded to such a point where the ridges and valleys of the fingerprint are no longer distinguishable by the reader.  In extreme cases the employee can only clock using a PIN or proximity card.  See the CS TimeClock Web Interface Manual, Changing a Card or PIN number:  Reader Required.

    With the Lumidigm reader try to enroll the employee's fingers using the Slow enroll type to get a sense of the quality of the fingerprints.
