ZoneCard

[5] Paper ZoneCards are no longer on sale but can still be used until their printed expiry date[6] Prior to the modernisation of the scheme the SPT area was split into 9 regions distinguished by a letter:[7] These are further subdivided into zones dividing the main towns of the area for example Ayr, Prestwick and Troon are in A1, A2 and A3 respectively; there are 77 zones in total.

The city centre is served by both inner Glasgow zones, and purchasing one of these entitles the user to use the subway system in both areas.

A Legacy 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.

With a vast amount of transport providers—across bus, rail, and ferry services—in the scheme, there are very few companies who do not accept ZoneCards.

Aside from the previously mentioned administration costs, the scheme is designed to be self-supporting, unlike some other tickets which are subsidised with public money to help the significant percentage of households in the region that do not have access to a car.
