@mclaus - I woyulkd suggest, just as we do with credit cards, that an order and the card information are sent separately. That way at least two parts of the system have to be comproimised before damage can be done.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
