NFC Mobile Wallet Developed in Association with Tuxedo and MasterCard

The Challenge

With c.12 million people in the UK owning NFC enabled cards and 43,000 contactless payment terminals already installed in the UK, Proxama worked in association with Tuxedo Money Solutions and MasterCard to develop an end-to-end mobile NFC payment solution that could be used by organizations wishing to launch mobile contactless payment services. The application needed to be simple, secure and easy to use.

Our approach

Using a consultative approach we worked with MasterCard and other project partners to define the solution requirements, this lead to the production of a user-driven slide deck and detailed integration plans for the proposed scope of work. Proxama developed a mobile phone based wallet application and worked in collaboration with Tuexdo Money to deliver an end-to-end Pre-Pay Mobile Wallet solution.
