The elephant in the room is that security on current credit cards is pretty much broken. That holds true for both mag stripe cards in the US and smartcards in Europe. There is a void in the market for credit payments as a result, which this could fill if they do it right (big 'if').
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.
