Abstract

A magnetic ticket validator includes a housing having a ticket receiving channel for receiving a coded magnetic ticket with a heat source adjacent the channel in the form of a flashbulb, with an exposure slot exposing a magnetic strip on the ticket to the flashbulb and a coded masking tape, for imposition of a binary code on the magnetic strip upon initiation of the flashbulb. The heat from the flashbulb heats selected portions of the magnetic tape exposed by the mask.
