Emisys develops ticketing and NFC cashless payment solutions for festivals and major events. I designed interfaces across the whole ecosystem: from web ticketing to top-up kiosks, point-of-sale interfaces, mobile applications and a complex management back-office.
The Emisys system covers two major services: ticketing (purchase, scanning and entry control) and NFC cashless payments (wristband top-up and contactless payment in festival bars, food trucks and shops).
Each service involves distinct interfaces: web for festivalgoers, touchscreen kiosks for top-ups, ordering applications for points of sale, and a management back-office for organisers and Emisys administrators. The main challenge was designing for non-standard devices, especially interactive kiosks, while maintaining visual and functional consistency across all products.
My mission covered the entire product ecosystem: UX thinking on user journeys, then UI design of reference interfaces for the development teams.
Analysis of usage, user profiles and constraints specific to each interface, especially kiosks and checkout applications in demanding conditions.
Creation of interfaces for web, mobile, touchscreen kiosks, points of sale and the management back-office, with very different usage constraints depending on the device.
Maintaining a coherent visual and functional logic despite the diversity of devices and user profiles, from festivalgoers to system administrators.
Each interface meets radically different needs: speed and autonomy for festivalgoers, efficiency and reliability for production teams, and full control for organisers and administrators.
Online ticket purchase, seat selection, festivalgoer account management and ticket consultation. A responsive interface designed for pre-event use.
Autonomous touchscreen interface for topping up an NFC wristband with a bank card or prepaid credit. Designed for fast, unassisted use in a bright and noisy environment.
Ordering and checkout interface for bars and food trucks: order taking, NFC wristband payment validation, item and stock management in real time.
Mobile ticket scanning interface at festival entry: fast validation, zone-based access management and clear visual feedback for security teams.
Complex application for organisers and Emisys administrators: system settings, management of tickets, points of sale, volunteers, staff and financial flows.
Designing for an interactive kiosk requires different rules from web or mobile: touch target sizes, readability at a distance, very short flows, error handling without a keyboard. The work required device-specific thinking before any interface production.
Identify all devices, user profiles, critical journeys and dependencies between interfaces to define design priorities.
Analyse the specifics of kiosks (screen size, reading distance, noisy context), mobile scanning apps, points of sale and the back-office.
Design the journeys and key screens for each interface, taking specific usage flows into account: speed for kiosks, efficiency for POS, completeness for the back-office.
Deliver detailed UI interfaces adapted to each device, used as reference models by developers for implementation.
Refine interfaces based on feedback from technical teams and first field feedback during event deployments.
Interfaces that work in difficult conditions: outdoors, noise, variable light, event stress, and for users who have neither the time nor the desire to search.
Each deliverable covered a specific device, with its own usage rules, technical constraints and functional objectives.
Online ticketing, festivalgoer account management and entry scanning app: responsive interfaces designed for individual use before and during the event.
Touch interface for cashless top-up kiosks: short flow, large touch areas, clear visual feedback, error handling without keyboard and adaptation to a bright, noisy context.
Checkout interface for bars and food trucks: fast order taking, NFC wristband payment validation and real-time item management.
Complete management application for organisers and administrators: system settings, access management, volunteers, points of sale and event financial flows.
The mission delivered a coherent set of interfaces across very different devices, adapting UX and UI choices to the constraints of each usage context. The challenge of interactive kiosks, with non-standard interfaces, autonomous use and difficult environments, was one of the most stimulating aspects of the project.
The particularly complex management back-office required in-depth work on information architecture and feature hierarchy to make a dense system usable by profiles as different as volunteers, organisers and Emisys technical administrators.
