Worldpay POS Native Android
New work for Worldpay Payments. Point of Sale terminals (POS). Lead UX, RNIB certification, stakeholder liaison, user research and testing
Worldpay wanted to create an 'experience layer' over the new Android-based Ingenico Axium DX8000 handsets. After extensive research and development, a new visual language and design system was commissioned, a project that I led the design direction and UX as part of a cross-functional agile team of well over a dozen people, from PMs to QAs.
The design was a synthesis of the latest Google Material Design language, and Worldpays own new design language. Accessibility was placed as a much higher priority, given the use cases, potential issues and huge constraints associated with POS devices. The app needed to be fully certified by the in the UK.
RNIB Certification
Obtaining RNIB ‘certification’ for a native app is a negotiation rather than a strict binary decision.
Step one: Document the key screens and journeys, and make sure that the main accessibility dealbreakers are taken care of. Type size, contrast, colours and legibility all need to be nearer to AAA than AA, and the key payment flows need to have accurate audio transcription for blind and sight impaired users.
Step two: Submit screens and flows to RNIB. The process starts with a full audit, and the feedback comes in the form of a report, where the issues are graded in a traffic light system, red being a hard fail, amber being an advisory, and green being a full pass.
Step three: Make changes. This is where most teams fall down. Accessibility is not a binary thing. It’s now time to create a balance between form and function, but retaining the quality of visual design whilst balancing the accessibility. Usually a good team will sit down and negotiate these edits, mediated by Product/PMs.
Step four: Resubmit. Again there is no ‘hard pass’ or ‘hard fail’. But a good team will have taken care of the reds and satiated the ambers. Anything left now is an amber, that for whatever reason, is not going to be fixed, be it tech constraints or a matter of team agreement on visual design or branding considerations.
