Prompted by the business expansion of the Octopus card, Octopus Holdings Limited was formed in 2005 after a company restructure of Octopus card operator Octopus Cards Limited. The Octopus card is used by card holders as an electronic payment system, and as such, the Octopus card system is considered a commercial business and is regulated by the Hong Kong Monetary Authority. The non-commercial businesses of the company, such as the consumer rewards program, consumer market research, and investment holdings, on the other hand, are not subjected to such regulations. The company restructure placed Octopus Cards Limited as a subsidiary of Octopus Holdings Limited, while the non-payment businesses of the company were placed under other subsidiaries, such that its payment businesses are independent of its non-payment businesses. Additionally, Octopus Holdings Limited has also expanded the use of the Octopus card system internationally, operating its businesses outside Hong Kong under a subsidiary.
