Case Study / Service Design / UI UX

Remote Supply Infrastructure

A mobile supply system for remote exploration, designed around one simple loop: access essentials in the field, then review and complete payment later on mobile.

This project rethinks the vending machine as a lightweight service system for hikers, explorers, and travelers moving through environments where stable infrastructure cannot be assumed.

Overview

Designing access before payment

The project focuses on a two-touchpoint system. The kiosk handles urgent, in-field access to supplies, while the mobile interface supports later review and payment in a calmer context.

Context

Designed for people in remote environments where water, food, medicine, and first-aid supplies may not be available through fixed infrastructure.

Advantage

The main interaction happens on-site through a simple kiosk flow, while payment is intentionally deferred to a lightweight mobile companion.

Outcome

A clearer service logic: immediate access at the station first, followed by post-trip review and payment on mobile.

Service Flow

One continuous journey

The system reduces field interaction to only the most essential steps, then shifts administrative actions into the app after the trip.

01

Authenticate at the station

02

Select essential supplies

03

Confirm pickup

04

Review purchases later

05

Complete payment in app

Primary Touchpoint

Kiosk UI

The vending machine is the primary touchpoint. It is designed to stay simple in the field: authenticate quickly, choose clearly, and confirm before dispensing.

Field interaction

Fast access under remote conditions

The kiosk flow prioritizes large touch targets, direct navigation, and a reduced decision path so users can get what they need with minimal friction.

Access Supplies kiosk screen — 01 · Access supplies through face scan or ID scan

Choose Supplies kiosk screen — 02 · Choose supplies through a simplified main screen

Confirm Pickup kiosk screen — 03 · Confirm selected items before pickup

Secondary Touchpoint

Mobile Payment Flow

The mobile interface is intentionally secondary. It only exists to review recorded purchases and complete payment after the trip, rather than interrupting the field experience.

Post-trip review

Payment happens later

Instead of asking users to handle identity, purchase, and payment in one place, the system separates urgent access from administrative follow-up.

Trip Summary mobile screen — 01 · Trip summary shows the recorded visit

Purchase History mobile screen — 02 · Purchase history supports item review

Complete Payment mobile screen — 03 · Final payment is reduced to one primary action

Reflection

Clarifying the system mattered more than expanding it.

The biggest improvement came from separating urgent access from later payment. Once the kiosk no longer tried to handle every part of the process, the system became easier to understand and easier to use.

This project reinforced an important lesson for me: service design is often less about adding more features, and more about deciding which actions belong to which touchpoint.
