Are there biometric tools for tracking employee attendance e.g. fingerprint recognition, facial image capture or Bluetooth sensing for clocking on/off to a shift?

Yes. Roubler offers clocking on/off to a shift via a mounted lockable tablet fixed to the wall of the premises along with image capture to this device. Roubler also provides an option of a downloadable desktop application should a site not have a hardware requirement. Fingerprint scanning and facial recognition are in development.
