Project description:
"I need a compact piece of software that lets my vending machines accept mobile-wallet payments seamlessly. The machines already run on standard MDB hardware; what’s missing is the logic that listens for a purchase request, routes it through a secure local wallet gateway (Indonesia's QRIS), confirms the transaction in real time, and then triggers product dispense.
Key points you should know
• Core focus is payment processing and UI, not inventory .
• Only mobile wallets must be supported at launch; credit-card mag-swipe, cash and other options can stay out of scope for now, but the code should be clean enough to extend later.
• The vending controller expects MDB-compliant signals, so familiarity with MDB/DEX, RS-232 or equivalent serial protocols is important.
• Security and reliability are non-negotiable—TLS for all network calls, graceful recovery on network drop, and clear audit logs.
Deliverables
1. Compiled application (or firmware module) ready to load on our ARM-based controller.
2. Source code with build instructions and minimal external dependencies.
3. A short setup guide that shows how to register wallet credentials, map them to product prices, and test a live purchase.
When you respond, please highlight prior experience integrating mobile wallets or other contactless payment flows into embedded or IoT devices. If you’ve worked with vending hardware or MDB before, mention that up front; it will put your proposal at the top of my list." (client-provided description)
