The Octopus card, a smart electronic money payment system, was introduced in September 1997 to provide an alternative to the traditional banknotes and coins. Available for purchase in every stop of the Mass Transit Railway system, the Octopus card is a non-touch payment system which allows payment not only for public transport (such as trains, buses, trams, ferries and minibuses), but also at parking meters, convenience stores, supermarkets, fast-food restaurants and most vending machines.
