The Challenge<\/h3>\n\n\n\n

Develop a secure, autonomous payment architecture where IoT devices could both make and receive payments, demonstrated by an interactive, playable prototype.<\/p>\n\n\n\n

My Role<\/h3>\n\n\n\n

I partnered with a payments agency to build the initial Raspberry Pi prototype with stored credentials. I then collaborated with Intel to migrate the credentials into a secure enclave called SGX. I built a Lego cityscape with a large LCD \u201csmart charger\u201d station and a custom Lego camper van housing a compute stick with it\u2019s own colour LCD screen.<\/p>\n\n\n\n

Solution and impact<\/h3>\n\n\n\n

Users drive the camper van around the cityscape, when it rolls over a charging sensor, the vehicle autonomously discovers the charging station, negotiates payment (including supercharging for low battery), pays securely, and the charge is released by a trusted trigger.<\/p>\n\n\n\n

The large dashboard screen displays real-time negotiation data and orchestration, making the invisible IoT payment flow visible and educational. This hands-on demo engaged audiences at events, sparking conversations about machine-to-machine economies – whilst showcasing secure, practical IoT payments in a playful format.<\/p>\n\n\n\n

Depth of technology<\/h3>\n\n\n\n

WiFi comms link the Intel Compute Sticks (vehicle and charger) running C# software, with payment credentials protected in Intel SGX secure enclaves. Custom Lego builds, contain the IoT hardware, the camper-van houses the Compute Stick, NFC sensor and LCD, and the cityscape features RFID\/NFC sensors, Compute Stick, and LCD, and a large dashboard screen.<\/p>\n\n\n\n

The architecture demonstrates discovery, negotiation, secure payment, and automated service release – all in a tangible, interactive setup.<\/p>\n\n\n\n
