Bringing screens to your product — from screen design to payment integration
A showcase of a character capsule (gacha) vending machine UX designed and implemented from scratch. It features a dynamic layout that alternates between full-screen ads and payment guidance, plus a payment and dispensing state machine.
How this HMI works
It implements a dynamic split layout that switches between a full-screen ad on the left and price and card-payment guidance on the right, providing card (NFC · IC) and QR payment flows, an approve→dispense→complete state machine, and a hidden admin menu. The payment terminal, dispensing motor, and sensors are based on a serial-integration design.
Key features

What you view and control on screen
How it connects to your equipment
Every EGNOX Custom HMI commonly supports Wi-Fi and Ethernet networking, OTA wireless firmware updates (signature verification and rollback), remote screen viewing via a web browser, and multilingual operation (Korean / English). The communication register map is mapped during the screen-design phase to match the equipment model.
