The Octopus card is a rechargeable contactless stored value smart card used to transfer electronic payments in online or offline systems in Hong Kong. Originally launched in September 1997 to collect fares for the city's mass transit system, the Octopus card system has since grown into a widely used payment system for virtually all public transport in Hong Kong. It is also used for payment at convenience stores, supermarkets, fast-food restaurants, on-street parking meters, car parks, and other point-of-sale applications such as service stations and vending machines. The Octopus card has been internationally recognised, winning the Chairman's Award of the World Information Technology and Services Alliance's 2006 Global IT Excellence Award for being the world's leading complex automatic fare collection and contactless smartcard payment system, and for its innovative use of technologies. According to Octopus Cards Limited, operator of the Octopus card system, there are more than 14 million cards in circulation, twice the population of Hong Kong. The cards are used by 95 percent of the population of Hong Kong aged 16 to 65, generating over 10 million daily transactions worth a total of about HK$29 billion (US$3.7 billion) a year.

Chung Sze Yuen (Sir S.Y. Chung, GBE, GBM) (Chinese: 鍾士元) (3 November 1917 – 14 November 2018) was a mechanical engineer, industrialist and Hong Kong politician. He succeeded Sir Yuet Keung Kan, GBE (簡悅強), as the Senior Unofficial Member of the Legislative Council and Executive Council in 1980 and served in the latter body until his first retirement from politics in 1988.

He has been more influential in Hong Kong politics when Tung Chee Hwa became the Chief Executive of Hong Kong, when he was invited by Tung as the convenor of the non-official members of the Executive Council.
