  • Q2.Fingerprint Flash Drive AH650 USB3.0 Q&A

      Q1.  When do I need to use AH650’s built-in Fingerprint Management Application?

      A:  Following are the situations when you need to use Fingerprint Management Application:

      (1) When using AH650 for the first time, you need to enroll administrator’s fingerprints with the application on your computer to activate access permissions.

      (2) Adding or deleting user’s fingerprints.

      (3) Changing administrator’s fingerprints.


      Q2.  Why can’t I enroll my fingerprints with AH650 plugged into a USB port on my computer?

      A:  Access permissions on AH650 Fingerprint Management Application can only be activated on a computer running Windows XP and later. Once administrator’s fingerprints are enrolled, you can use AH650 under the following environments:

      • Windows XP/7/8/8.1/10
      • Mac OS 10.4.x or above
      • Linux 2.6.x or above


      Q3.  How many fingerprints can I register on AH650?

      A:  AH650 supports up to 10 fingerprints for registration: 2 for administrators, 8 for users.


      Q4.  What’s the difference between administrator and user accounts on AH650?

      A:  Administrators and users have different access permissions on AH650 Fingerprint Management Application. To provide higher security for data usage, only administrators can log in to Fingerprint Management Application to add and delete users, while both administrators and users can read and write once their fingerprints are successfully authenticated.


      Q5.  Why do I need toenroll two fingerprints for administrator? Why can’t I delete administrator’s fingerprints after they are enrolled?

      A:  As a precaution, you will be compulsorily asked to enroll two fingerprints for administrator so that if either of the fingers becomes unavailable for authentication due to injury, you will have an alternative finger to use.

      Due to the same safety reason, you can make modifications to administrator’s fingerprints but can never delete them.


      Q6.  Can I enroll fingerprints on multiple AH650 on a computer at a time?

      A:  Due to security concerns, only one piece of AH650 can be used on a computer running Windows XP and later for fingerprint enrollment. Once the enrollment is complete, you can access and manage data with multiple AH650 on a computer.


      Q7.  Why only the “Public” partition is recognized when AH650 is plugged into my computer?

      A:  AH650 storage capacity is divided into two partitions: Public and Secure. The “Public” partition is accessible to everyone, including read/write access, while the “Secure” partition, occupying the most storage space, is fingerprint-secured and can only be accessed when the fingerprint in question is authenticated.


      Q8.  How should I store AH650 when it is not in use?

      A:  When AH650 is not in use, please cover the USB connector and sensor plank with the protection cap to protect from physical damage, dust, dirt, grime, and liquids.


      Q9.  Why my fingerprints which have already been enrolled failed to be recognized by AH650 when I place my finger on the sensor plank?

      A:  Please make sure there is no excessive water splash or greasy dirt on your finger because this can lead to recognition failure. However, if your finger is too dry, your fingerprint may not be read either. If this occurs, please wet your finger with a breath of warm air and try to log in again.


      Q10.  How can I remove AH650 from my computer properly?

      A:  Depending on the OS running on your computer, do any of the following:

      1. Windows: Go to “Computer”, right click the AH650 device icon, and select “Eject”. Alternatively, move your mouse cursor to the bottom-right corner where a USB icon is displayed. Click the USB icon and select “Eject [Device Name]” to remove AH650.
      2. Mac: Drag the USB icon from the Desktop to “Trash”, or click the “Eject” button next to the USB device in the Finder window sidebar.
      3. Linux: Depending on the interface you are using, do either of the following:
        • Graphical User Interface: Move the mouse cursor to the USB icon and right click to select “Eject”.
        • Command Line Interface: Enter commands, such as #eject or #unmount, to remove AH650.


      Q11. Why the text and icon in AH650 Fingerprint Management Application will exceed the column?

      A: If user had modified the text size of Windows system, it may caused this situation.

      Please wait for new Fingerprint Management Application released to fixed this problem.
