Don't you have chips in your debit and credit cards already for normal transactions by physical contact through the gold pads on the card, rather than just the magnetic stripe (which is almost obsolete here in the UK and Europe)? If so, then zapping the chip would prevent you using it for normal chip'n'PIN transactions. Sheilding would have to be in the wallet, or else you'd need to make it removable to access the chip contacts.
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.
