Appearing in the dock of Belfast Magistrates' Court in jeans and a grey jumper, 43-year-old Anthony McDonnell spoke only to confirm that he understood the charges against him.
McDonnell, from the Upper Springfield Road in west Belfast, faces a charge of collecting information likely to be of use to terrorists, namely five vehicle registrations, on a date unknown between 1 October and 12 December last year.
He faces a further charge of possessing useful information on 14 December last year in that he allegedly had addresses and vehicle registration details of members of the security forces.
A detective constable told the court he believed he could connect him to the charges.
Under cross examination from solicitor Philip Breen, the PSNI officer confirmed that since the searches before Christmas, numerous items including computer storage media were being examined as part of a "forensic strategy" in the "live" investigaton.
The officer told the court and Mr Breen that by the time the case is next before the court on 31 January the PSNI would endeavour to have a timetable for the results of the examinations.
No bail application was lodged with the court.
District Judge George Conner remanded McDonnell into custody to appear again on 31 January.
