In 2000, the Hong Kong Monetary Authority granted a deposit-taking company license to the operator, removing previous restrictions that prohibited Octopus from generating more than 15 percent of its turnover from non-transit-related functions. This allowed the Octopus card to be widely adopted for non-transit-related sales transactions. On 29 June 2003, the Octopus card found another application when the Hong Kong Government started to replace all its 18,000 parking meters with a new Octopus card-operated system. The replacement was completed on 21 November 2004.
