Call me paranoid, but I want my "wireless wallet" to require me to confirm the charge in some fashion. Otherwise I see "wireless pick-pockets" and similar scams arising. A cell phone already includes a keypad and display, so it could show the charge amount and you then confirm (or even enter a PIN) via the keypad. But that would have to be separate from my service provider, otherwise they would charge for purchases just like they now charge for texting and everything else.
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
