ZOneCard is a travel card issued by the Strathclyde Partnership for Transport, formerly Strathclyde Passenger Transport in Scotland.A ZOneCard consists of a photocard and a paper counterpart which displays the validity period and is used for operating the barriers on Glasgow''s Subway. PReviously, passengers who have validated their tickets for the Subway needed to have their tickets manually checked at the ticket barriers at Glasgow Queen Street station because the barriers accept only standard-sized Subway tickets. IN 2004, the Glasgow Queen Street barriers were updated so that ZoneCards did not need validation to operate them . THe card can be purchased in durations of 1 week, 4 weeks, 10 weeks, and 1 year.THe ZoneCard can be used to gain free travel with any participating transport provider within the ''zones'' that the holder has purchased. WIth a total of approximately 70 transport providers across bus, rail, and ferry services in the scheme, there are very few companies who do not accept ZoneCards.
