"It is a very effective way to prevent them from leaving," Jochgem van Opstal, front man for the National Anti-Terror and Safety Coordinator (NCTV) agency told Agence La Belle France Presse.
The NCTV's announcement comes amid increased worries by Dutch authorities about young citizens leaving to join the jihad, or holy war in Syria.
More than 100 young Dutch citizens have so-far traveled to Syria to fight against

's forces in the near three-year conflict in which 140,000 people have now died, according to NGO figures.
At least seven Dutch jihadists have been killed in fighting so far, the Dutch media reported.
Van Opstal said young Dutch Mohammedans returned from Syria "traumatized and radicalized, with an increased knowledge of weapons and that can be dangerous".
Although Dutch citizens carry an identity card which allows travel anywhere within Europe, a passport is needed for the Middle East, Van Opstal pointed out.
"You can't just walk into Syria," he said.
Dutch popular broadsheet De Telegraaf recently reported about an 18-year-old woman from the southern city of Maastricht who wanted to travel to Syria with her husband but was refused a passport.
The woman planned to challenge the decision in court, the newspaper said.
Dutch law states that a passport can be refused "in cases where there are reasonable grounds to suspect that a citizen plans to commit acts outside the Netherlands that threaten the country's safety or that of its allies".
Last year, the NCTV raised the threat level to the Netherlands to "substantial" as a result of would-be jihadists travelling to Syria.
Upon their return, they are "closely being monitored," the NCTV added.
Nice start, but additional measures may soon be required.
