was delivered in December 2012. The trams have wrapped advertisements for promoting local events and commercial advertising. Fares and ticketing Fare structure Ticketing and fares are integrated with Lothian Buses. A proof of payment system applies. The single fare is the same as on Lothian Buses for most rides, and day tickets and Ridacards are valid on trams and buses. However the tram fare from the centre to the airport is more expensive than the bus, costing £6.50 one-way. Weather permitting, some airport passengers make the relatively short walk of to/from Ingliston Park & Ride where the normal fare of £1.80 applies. The "Ridacard" is a smartcard season ticket issued by Transport for Edinburgh; it is valid on both Edinburgh Trams and Lothian Buses (available for 1 week, 4 weeks or annually). On 1 September 2014, a rechargeable pre-paid smartcard for single journeys on both buses and trams, called "Citysmart", was introduced. Free travel is available to holders of City of Edinburgh Council-issued Scottish National Entitlement Cards which are eligible for concessionary travel, and for a companion travelling with the cardholder of National Entitlement Cards with a companion entitlement. Passengers with National Entitlement Cards eligible for concessionary travel but issued by other local authorities are not offered any fare concession, with the exception of blind or visually impaired cardholders. An "onboard fare" of £10 is charged to passengers who have not pre-purchased a ticket or validated either a Ridacard, a National Entitlement Card or an m-ticket before boarding. Ticket machines At the request of Lothian Buses, installation of 30 ticket machines at key bus stops began in 2007. Passengers had to purchase tickets before boarding the bus, reducing dwell times, but the machines were not popular with users and were scrapped in 2011. Consideration was given to installing similar on-street ticket machines, and new, advanced machines (capable of reading smartcards and accepting credit/debit cards) were installed in early 2014 at each tram stop. The new ticket machines are the Galexio-Plus type supplied by Flowbird Transport Ltd. Ticket machines do not accept banknotes or give change. The minimum spend for a card transaction was originally £3 which was more than the cost for a single ticket. The minimum spend was scrapped in September 2019 following complaints from customers and negative press comments. Services Services run every 7 minutes throughout the entire line, between St Andrew Square and Edinburgh Airport. Bicycle policy
