Mox

Background

Mox was among the first batch of banks to obtain the virtual banking licence from Hong Kong Monetary Authority in March 2019.

In late 2019, I moved to Hong Kong to joined as Senior Product Designer to the founding design team for Mox and I led the user experience and design for logging in, paying bills, requesting money and FX.

The Challenge

Moving to Hong Kong was a bold move and there was a lot to learn. The cultural approach to banking was different to the UK. The locals in Hong Kong were not familiar with the concept of a bank that existed solely on your mobile phone. I also learnt that Hong Kong locals were extremely financially literate. It was commonplace for the average Hong Kong person to have 2-3 credit cards and they were adept at acquiring the credit cards in a bid to get the best deals and discounts. It was also helpful that all of my colleagues were lifelong Hong Kong locals so I was able to learn first hand about the cultural insights regarding money, design and day-to-day life. Socialising with colleagues at lunch really helped me feel embedded.

Paying bills in Hong Kong is a painful experience. Typically bank account users need to go to their local 7eleven or pay their bills directly in the local bank branch

The Approach

I was tasked with solving the problem of helping users efficiently pay bills within the app.

The problems to solve was simple but collating the data to make the user flow was difficult. In Hong Kong everyone paid their bills at their local convenience store so we were introducing a brand new behaviour into the market.

  • The users needed a frictionless way of searching for the company that they wanted to pay.

  • The user needed to supply an unique reference number or account number

  • The user needed to have confidence that they were paying the right company.

User Testing

There are a finite amount of utility companies in Hong Kong. By collating the payment details for each company we could save Mox users the hassle of paying their bills in person.

Three rounds of user testing were conducted in total. All tests were conducted in Cantonese with Hong Kong Locals. I produced prototypes for the tests. The test were conducted by the User Research Lead. The tests included the following

  • Discoverability of the Pay Bill feature

  • Pay bill flow usability

By the third round of test, 100% of users were finding the pay bill feature. As most Hong Kongers have dual nationality the feature wasn’t unfamiliar as they have experienced frictionless bill payments in other countries

The Result

The UX challenges were straightforward but the key challenge with this project was to ensure that there was consistency across the other squads as we working simultaneously for launch. A holistic approach meant that we needed to flow map all of the screens in a bid to spot areas of the app that looked inconsistent.
