Irrespective of which TOC operates them, machines offer a full range of travel tickets: point-to-point tickets from the home station to all other National Rail destinations, One Day Travelcards, tickets to Transport for London zonal destinations, Plusbus add-ons and weekly season tickets. At some stations, products such as car parking tickets and local rail rovers can also be bought. There were some exceptions in the system's early years though. Early machines were not equipped with Ticket on Departure (ToD) capability, which allows tickets bought online to be collected from a self-service ticket issuing machine at a station. Instead, they were reprogrammed to be ToD-compliant when the feature was introduced, and all machines now offer ToD. The first ToD-equipped machines were at larger stations on the First Great Western network, which were upgraded in summer 2007. At first, the original ScotRail machines installed in early 2004 could not issue new season tickets: only renewals of existing tickets were available. The set of machines operated by the Merseyrail TOC have only ever sold tickets to other Merseyrail stations; and until late 2006 they only sold full-price adult and child tickets. Discounts for concessionary passes such as the 16–25 and Senior Railcards were programmed in at that time.
