Kvapay Mobile
Kvapay Mobile — mobile app for crypto invoices
concept:
Mobile POS for accepting crypto payments: the merchant enters the amount, selects the network/coin, generates an invoice via QR or NFC, and receives instant status updates. Dark theme, neon-green accents, with a focus on speed and clarity for offline points of sale.
Objective:
To make crypto acceptance as simple as a regular payment terminal: fast login and device linking, a minimal invoice creation flow, clear statuses, and transparent transaction history with filters. Reduce cognitive load and shorten the time required for each transaction.
