Tickets printed at point of issue

This is the more common system for operations that do not possess electronic ticketing products. Ticket issuing machines can either be manually [mechanically] operated or, more commonly, electrically operated. The machines can be carried by roving conductors, or fixed to the vehicle for use by the driver or a seated conductor.
The devices hold blank paper rolls [although the reverse side of the blank rolls can be used for legal, promotional or advertising purposes]. This provides a major security advantage to the operator, in that the ticket stock holds no value and hence is not a target for forgery or theft.

The range of ticket products sold and the range of data and revenue analyses generated by the machine is limited but does vary, depending on the complexity of the transport system and the requirements of the operator or regulator. Machines can be programmed to enable identification also of the time, date, route, duty, vehicle and crew characteristics.
A ticket printed at the point of issue also acts as a receipt for the fare transaction.
