Payment is a kind of feedback system that making a transaction of purchases at Octopus-enabled retailers. Holding the card against or waving it over an Octopus card reader from up to a few centimeters away without the user taking out the card. The reader will acknowledge payment by emitting a beep sound, and display the amount deducted and the remaining balance of the card in 0.3 seconds.
When riding the MTR system, the entry point of commuters is noted when a passenger enters, and the appropriate amount based on distance traveled will be deducted when the users show their card again at the exit point. The MTR charges less for journeys made using an Octopus card instead of conventional single-journey tickets. For example, the adult fare of a single journey from Chai Wan to Tung Chung is HK$20.70 with an Octopus card, and HK$23.50 with a single journey ticket. Other public transport operators also offer intermittent discounts for using Octopus cards on higher fares and round-trip transits on select routes.
On 6 November 2005, Octopus Cards Limited launched Octopus Rewards, a program that allows cardholders to earn rewards at merchants that are partners in the program. Participating merchants provide consumers with tailor-made offers and privileges. The rewards that the program offers are in the form of points, or reward dollars, stored on the card. Once a card is registered for the program, the cardholder may accumulate reward points by making purchases at participating merchants, and payments may be made in the form of cash, credit cards, or Octopus cards themselves. The rate at which reward points are earned per dollar-amount purchase differs by the merchant at which that the purchases are made. At Wellcome, for example, one point is earned for every purchase of HK$200; and at Watsons, points are earned at a rate of 0.5 percent per dollar amount of a purchase. Once these reward dollars are accumulated, they may be redeemed as payment for purchases at partner merchants for at least HK$1 per reward dollar. To redeem the accumulated reward dollars, cardholders must use the entire value amount in whole, and may not elect to use it partially. If the purchase price is lower than the amount of reward dollars available, the amount difference remains stored on the card. Founding partners for the Octopus Rewards program include HSBC,UA Cinemas, Watsons, Wellcome, and McDonald's. Enquiring balances, adding value and refunding
Octopus card enquiry machine
In MTR stations, enquiry machines can be found where cardholders may place their Octopus cards on the machines and the machines will display the balances along with a history of last ten usages. Monetary value can be added to the card through a number of ways. Add Value Machines, located at MTR stations, can be used to add more value to the cards. The machines accept cash, and selected machines are also able to accept Electronic Funds Transfer.Alternatively, value may be added with cash at authorised service providers such as PARKnSHOP, Wellcome, Watsons, 7-Eleven, Circle K, and Café de Coral, and also at customer service centres and ticketing offices at other transport stations. An Octopus card may store a maximum value of HK$1,000, with an On-Loan card having an initial deposit value of HK$50 and a Sold card having no initial deposit value. Negative value is incurred on a card if it is used with insufficient funds—both types of cards may carry a maximum negative value of HK$35 before value needs to be added to them again for use. At the time, the maximum cost of a trip on any of the rail networks except the Airport Express and first class of the MTR East Rail line was HK$34.8, the cost of travelling between East Tsim Sha Tsui Station and Lo Wu Station; the current maximum cost is $47.5, the cost of travelling between Disneyland Resort Station and either Lo Wu Station or Lok Ma Chau...
