Initial Ideas


  • Communications
  • Advertisements (different buildings have different purposes)
  • Different floors have different purposes (restaurants, offices, shops, clubs, bars etc.)
  • Signage
  • Information (real time, date and weather)
  • Map of the building's layout (static and digital map)
  • Eco-friendly technology (AC water curtains and solar panels)

Ticket Gate Machine

  • Technology Used
  • How it works
  • Efficiency and effectiveness
  • Information tracking and display (database, time, location, date, remaining balance)

Research Project

Analysis of Octopus Cards


What is an Octopus Card?

  • The Hong Kong Octopus card is a contactless travel card which will grant you access to all of Hong Kong’s public transport such as MTR (Mass Transit Railway), KMB (Kowloon Motor Bus), Citybus, Shops, parking, taxi, places that include Octopus Card readers (vending machines), New World First Bus and New World First Ferry.


  • Launched in September 1997 to collect fares for the territory's mass transit system, the Octopus card system is the second contactless smart card system in the world.
  • Led to the development of Oyster Card in London and Opal Card in New South Wales.

How it works

  • NFC (Near Field Communication) contactless cards such as smart phones and bank cards.
  • Unique numbers on each cards


  • Card theft
  • If the Octopus card is lost then anyone can use it, there is no security authentication when using the card this such a password/pin.)
  • Traceability(if someone wants to know where the money was spent then they cant find out as there is no user that assigned to the card

Software and Hardware System

  • Efficiency and effectiveness (It's really quick and easy to use with just a tap of the card on the octopus card readers.) The hardware required for the system is fairly simple, which simply uses a card reader.
  • Speed of the process is instantaneous
  • Information tracking and display (database, time, location, date, remaining balance)
  • Costs
  • Card balance can go into negative, this is from the deposit that is paid.
  • MTR Stations have different exits (logs in the entry station and exit station, calculates the cost of the journey.)
  • Samsung Pay co-operating with Octopus card to implement electronic Octopus cards.


  • Octopus cards are behind compared to using other technologies such as QR codes and NFC payments
  • More reliable and safe


  • The aim of this research was for us to look into the effectiveness and efficiency of the octopus card.
  • Gather knowledge and information by interviewing members of the public and shoppers on what they think about the emerging technology of Samsung pay with octopus cards.
  • We aim to interview 10


  • Interview members of public (about 10)
  • Photos
  • Online reviews (research info on pros and cons)
  • Interview locations: Central and Chai Wan


  • Do you own a Samsung phone?
  • Follow up for Yes - Would you use the Samsung pay over the octopus card? And why?
  • Follow up for No - Would you convert to using a Samsung phone to have digital access to octopus card? And why?


  • This is an image of an octopus card reader that supports Samsung Pay


  • We aimed to interview 10 people but we only got 5 responses due to a language barrier.
    • 3/5 said yes to owning Samsung phone, of which all 3 people said yes to using the Samsung pay over the octopus card
    • 2/5 said No to owing a Samsung phone
  • Yes:
    • Person 1: “Easier and more convenient than using an octopus card”
    • Person 2: “Mobile phones have better security than the normal octopus card”
    • Person 3: “I am constantly using my phone which makes it easier for me to pay for things such as shopping and MTR travelling.
  • No:
    • Person 4: “The main reason why I would not do this is because I might run out of battery on my phone, meaning that I won’t be able to use the app.”
    • Person 5: “I am currently using an iPhone so if this feature was available on Apple Pay, I would definitely make use of it”
  • Pros:
    • If the phone is lost or stolen, then there are security measures that prevents the Samsung octopus cards from being infiltrated.
    • Easier to use (payment process)
  • Cons:
    • Battery running low
    • Phone getting damaged (breakage, technical problems)
    • Samsung Pay is very rarely used, Google and Apple pay are much more popular.


  • From the results, we analysed that technology wins over the physical octopus card.
  • After researching we have realized that Samsung pay is much more efficient than the octopus card because it’s digital and convenient. With the octopus card you will constantly be thinking if it is in your possession or if you have lost it. Whereas, if you have your phone, you are guaranteed that your octopus card is always with you at all times. Also, Hong Kong is a busy city which means that it easy to carry only one device that does everything with minimal hassle.
  • The language barrier had a big impact on our research because we could have gained more results from the public.
  • If we had more time, we could have gone to a range of different locations in order to interview people.
