Caiz ATM Kiosk
Physical Terminal — Buy, Withdraw and Transact
Project Overview
CaizATM is the physical entry point to the Caiz ecosystem — a self-service terminal where someone with no account, no app and no crypto knowledge can buy Caiz Coin, withdraw, transfer and redeem vouchers.
Every assumption that holds for a phone breaks here. The device isn't yours, so nothing can persist after you walk away. You're standing in a public place, possibly with people behind you, so anything sensitive on screen is visible to strangers. There's no keyboard, no back gesture, and no ability to look something up mid-task. And unlike an app, an abandoned session leaves a live financial terminal open to whoever approaches next.
Project Highlights
Language before anything else. A public terminal serves whoever walks up to it. Language selection is the first screen, not a settings option — with flags rather than language names, so it works for someone who can’t read the current interface language.
New and existing users split at the door. The two journeys share almost nothing: one needs an account created, the other needs authentication. Branching immediately avoids forcing either through steps meant for the other.
Six actions, one screen, no nesting. Buy, withdraw, transfer, receive, balance and vouchers sit as equal tiles with icons. At a standing terminal, depth costs more than breadth — someone in a queue can’t afford to explore.
The live rate never leaves the screen. A persistent rate bar sits across every screen, because the exchange rate moves during a session and the user is making a financial decision without a second device to check against.
Private keys printed, not displayed. Public address and private key are visually separated and differently labelled, with printing as the primary path. A private key held on screen in a public place is a security failure regardless of how well the screen is designed.
A receipt as the artefact you leave with. Confirmation shows voucher value, amount spent and transaction address, then prints. The physical slip is what makes the transaction feel real to someone who has just handed over money for something intangible.
