The '''Octopus card''' ({{lang-zh|t={{linktext|八達通}}|j=baat3 daat6 tung1}}, {{small|[[Hong Kong Cantonese|Cantonese]])}} is a reusable [[Contactless payment|contactless]] stored value [[smart card]] for making [[Electronic money|electronic payments]] in online or offline systems in [[Hong Kong]]. Launched in September 1997 to collect fares for the territory's [[public transport]] system, it has grown into a widely used system for transport and other retail transactions in Hong Kong. It is also used for purposes such as recording school attendance and permitting building access. The cards are used by 98 percent of the population of Hong Kong aged 15 to 64<ref name="companyprofile" /> and the system handles more than 15 million transactions, worth over HK$220 million, every day.<ref name="companyprofile">{{cite web|title=Company Profile|url=https://www.octopus.com.hk/en/document/company_profile.pdf|publisher=Octopus Cards Limited|access-date=1 March 2018|date=September 2016|archive-date=1 March 2018|archive-url=https://web.archive.org/web/20180301225100/https://www.octopus.com.hk/en/document/company_profile.pdf|url-status=live}}</ref>

The Octopus card system was the world's second [[contactless smart card]] system, after the Korean [[Upass]]. It won the Chairman's Award at the [[World Information Technology and Services Alliance]]'s 2006 Global IT Excellence Awards for, among other things, being the world's leading complex automatic fare collection and contactless smart card payment system. Its success led to the development of similar systems elsewhere, including [[Navigo card]] in [[Paris]], [[Oyster card]] in [[London]], [[Opal card]] in [[New South Wales]], and [[NETS FlashPay]] and [[EZ-Link]] in [[Singapore]].
