The EMPA (European Mobile Payment Association / Association Européene pour le Payez Mobile) is an European commission regrouping six majors banks (BNP Paribas, Crédit Agricole-LCL, Crédit Mutuel-CIC, Banque Postale, Banque Populaire group, Caisse d’Epargne group, Société Générale) and four leading mobile phone service providers (Bouygues Telecom, NRJ Mobile, Orange and SFR). Its strategic goal is to promote and develop mobile payment solutions in the european market.
In 2008, whilst working for Axance I was the leading designer of a mobile payment app, using the contactless NFC technology (Near Field Communication). Taking a user-centred design approach, we started by auditing the competitors solutions, and designing user-scenarios. I designed screen wireframes for the app, as well as a fully interactive prototype, installed in a Nokia N95 phone. We then designed different usability testing protocols and conducted 2 waves of user testing in Paris and Strasbourg (32 users seen in context). Since the recommended solution was very well appreciated, we finalised the prototype and wrote functional specifications.
A few weeks later started a national pilot in France, for which more than 500 shops were equipped with NFC devices, enabling customers to use their mobile phone as a contactless credit card. Once again, this trial showed excellents results. 90% of customers expressed satisfaction and 59% stated they would buy the service once available. 82% of retailers also answered positively, being pleased by the ease of use of the solution.
