If electoral register is created by the EMB, what type of technology used for collecting registration data?

OSCE/ODIHR Needs Assessment Mission Report, Romania, Parliamentary Elections, 11 December 2016

“Voter registration is managed by the Permanent Electoral Authority (PEA), which extracts the electoral register based on a compilation of information from various government authorities, including the National Register of Persons’ Records, maintained by the Ministry of Interior. Since 2014, the PEA has introduced a centralized electronic register as a means to increase list accuracy and prevent multiple entries.”
