Why Biometric Profile Corruption Happens

Biometric Profile Corruption occurs when a USB data download is performed incorrectly, generally as a result of the following steps:

1. The user inadvertently downloads User data instead of the Attlog (attendance log) from the Clocking Terminal
2. As a result of this, two files are downloaded onto the USB: user.dat, containing a list of enrolled staff members, and template.fp10 or ssrface.dat, containing the encrypted biometric profiles of enrolled users 
3. These files are not deleted from the USB drive by the user
4. Some employees are added or removed from the ClockRite Software and an updated user.dat file is downloaded from the ClockRite Software onto the same USB
5. The new user.dat file no longer matches the template.fp10 or ssrface.dat file on the USB 
6. Both files are then uploaded to the Clocking Terminal, leading to a mismatch between users' names and their biometric profiles

As a result of this issue staff may see another users name when they clock in, and attendance events may be allocated to the wrong person.

How to Avoid the Issue in Future

USB Downloads should always be carried out with care, following our USB download guide. It is particularly important to ensure that files named template.fp10, template.fp.10.1, and ssrface.dat(for facial recognition systems) are promptly deleted from the USB stick. They should never be uploaded to the Clocking Terminal. 

Rectifying Biometric Profile Corruption

Delete All Users From the Clock

Delete All Data From the USB

Download current user data from the ClockRite Software

Upload current user data to the Terminal

Re-register Biometrics
