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

EU observation mission report on 2017 elections

“For this electoral cycle, the STAE conducted two updates of its biometric voter register database. In preparation for the presidential election, from 3 October until 23 December 2016, STAE registered a total of 743,150 voters, which represented an increase of slightly more than 100,000 (or 15 per cent) from the 2012 register. A total of 1,463 non-eligible voters under 17 years of age were also registered.”

EU observation mission report on 2017 elections mentions the use of biometric voter registration. However, there is no data on what features of voters were scanned during registration.
