This video is only for self viewing purpose, and is entirely not for commercial use.
I made this video only because there is no similar apps in playstore or elsewhere.
In fact, we are wasting a lot of paper in our daily life.
In the video, by using Octopus payment, the transaction details would be recorded in the smart phone.
Moreover, the details could sync with Google calender, so that we are able to work out the monthly expenses, and easily check back when/where/what we had purchased.
I use the theme from the Mr Chow's movie because I assume the great idea of this video would be matched with the energetic, uplifting, promising, exciting, and encouraging style.
I would like to thank all the labels appeared in the video.
I hope the labels would not mind as this is only a self entertaining assignment.
