UI/UX for a vending system for supplements and OTC products
UI/UX of a vending system for supplement distribution / retail / OTC. The project covered the design of a complete vending solution for supplements and OTC products in a self-service model. The goal was to deliver an intuitive, safe and scalable self-service system integrated with payments and age verification.
DESIGN CHALLENGE
The vending system had to combine retail sales requirements, legal constraints and user ergonomics. The interface had to remain intuitive without staff support.
- simplified product selection
- cashless payment integration
- age verification integration (ID scanner)
- clear order presentation on limited screen space
- adapting UX to users with different technology familiarity
USER INTERFACE DESIGN
We designed a clean touchscreen interface optimized for fast product selection. The solution included:

- large and readable product tiles
- clear hierarchy of information and prices
- simplified checkout flow
- quick payment and age verification process
- minimal number of operational steps
Simplicity, readability and transaction safety were the main priorities.
ARCHITECTURE AND SYSTEM LOGIC
The interface was designed as part of an integrated device architecture. The scope included:

- screen structure and navigation logic
- payment system integration
- age verification model integration
- stock state control
- product dispensing logic
The system was prepared for scaling and integration with retail sale systems.
SCOPE OF WORK
The project included:
- self-service purchase flow analysis
- information architecture design
- UI design for an embedded system
- payment and age verification logic integration
- screen sequencing and user journey design
- implementation-ready documentation handoff
IMPLEMENTATION OUTCOME
The implementation enabled:
- automation of OTC product sales
- higher sales safety through age control
- simplified purchase process
- integration of the vending system with retail architecture
Summary
The project is an example of integrating UI/UX, embedded systems and operational logic in a B2B retail model.
Designing a vending system or self-service device?
We design UI/UX for embedded devices, operator panels and vending systems - from concept to implementation-ready handoff.
The project covered a complete interface architecture and implementation-ready documentation for deployment in an embedded retail environment.
