The Octopus card is a rechargeable contactless stored value smart card used for electronic payment in online or offline systems in Hong Kong. Originally launched in September 1997 as a fare collection system for the city's mass transit system, the Octopus card system has grown into a widely used electronic cash system used not only for virtually all public transport in Hong Kong, but also for making payment at convenience stores, supermarkets, fast-food restaurants, on-street parking meters, car parks and many other point-of-sale applications (e.g. service stations and vending machines). In addition the system is used for access control to offices, schools and apartments. It can even be used to donate money to charities. [1] Using a card involves simply holding the card in close proximity above, or on, an Octopus reader, and cards can be recharged with cash at add-value machines or over the counter in shops (notably 7-Eleven and Circle K), or directly through credit cards and bank accounts.
