Project Description I am developing a self-service printing kiosk in Lisbon (printer vending machine for malls or airports). Users can print documents for a fee. I am looking for a developer or small team to build, integrate, and test the kiosk software. Two possible approaches are considered: On-screen kiosk UI (bilingual: English & Portuguese) with printer and payment integration QR-code based flow, where users control printing from their mobile phone The payment provider is not yet finalized, and I am open to technical recommendations based on your experience. The scope includes software development, printer integration, backend logic, and full testing. This is a real deployment project, not a prototype. Please share relevant experience, estimated timeline, and budget.
