If the EMB uses technology to collect voter registration data, is biometric data captured and used during registration?

The National Electoral Commission of Sierra Leone provides that Biometric Voter Registration (BVR) took place between 23rd January 23rd and March 26th, 2012. Registrant’s photo and thumb prints were captured.  This was to ensure there are no duplicated voters and ensure the integrity of the Voter’s Register. http://www.nec-sierraleone.org/Registration.html
