The German city of Bonn has installed a meter to tax prostitutes for soliciting on its streets at a rate of six euros (£5.30; $8.70) per night.
Those who fail to pay face fines or even a ban, and 264 euros were found in the meter when it was first emptied, according to AFP news agency.
Tax has been levied on prostitutes elsewhere but Bonn is the first city to use a meter, a spokeswoman said.
But a prostitutes' rights activist said the scheme amounted to double taxation.
