Calling cards are lucrative tool used by pimps

The use of calling cards to promote prostitution in Beijing hotels is an easy and lucrative way to reach clients, a woman engaged in so-called entertainment work was quoted as saying in a report by Beijing News on Monday.

"Pimping by cards costs less and earns a lot," the report quoted the woman as saying. "It is easy to do."

People involved in pimping distribute the cards, which typically advertise "services in different prices", to corridors or hotel rooms.
