The police have requested that taxi drivers identify any of their passengers by means of identity cards who wish to cross the green line.
The move is due to the rise in Palestinians robbing taxis in the center of the country.
On Wednesday night, there were two attempts to rob taxis in the center of the country. In one case, three Palestinians succeeded in robbing a driver they asked to drive them to Tira. They threatened to stab the man if he did not comply.
A second attempt to rob a taxi failed.
Since the start of 2006, over 30 cabs have been robbed in the center and Jeruasalem.
