Our focus

Our focus is on building a membership system that turns your phone into your wallet and redefine your everyday shopping experience.

Add all your loyalty cards to the app in seconds, collect reward points when shopping, discover exclusive offers and never miss rewards again.

Aim to make the daily shopping experience easy, engaging and rewarding.


For SME retailers,

if they want to self-develop their own membership systems, it’s not cost-effective at all, and they have limited resources and database for running the loyalty programs or making a dedicated membership app.

For Consumers,

it’s hard to bring tons of membership cards with them when they're out and about, and they even don’t remember how many membership cards they have, it brings us to think them the trouble of bringing all their loyalty cards.


We RECRUIT big and small (SME) retailers to develop the membership system.

We REWARD consumers with our Yahoo Points for every membership card and/or
transaction made through this app.

A simple and clever take on virtual loyalty-card wallet – exclusively for “Yahoo Membership” members

Primary research

Behavioral observations and interviews were done in the Causeway Bay area. We found out that there were lots of people having more than 10 membership cards. However, most of them didn't carry all the membership cards in their wallet. They said that they usually can't find the specific membership card when they need it in the shop. And they also just relay on using email to get the promotions but they didn't check promotion email very often. 


We did some brainstorming and storyboards of some potential designs. After that, we used the speed dating method to test our ideas. We found that like our research findings, users are willing to use mobile app for storing all the membership cards and gaining extra rewards.

User Flow & Wireframe

User Flow and Wireframe is sketched after doing the research and analysis. It helps to define the user experience of the app. I listed out the key purposes of the app and aim to design according to the user flow.
