Prabhakar, I think you misunderstand this application. The chip is the only thing used; there is no board. The chip gets embedded into the product (sewn into a seam, molded into a CD, etc). To verify an article is genuine the NFC interrogation asks the chip for its ID (using encrypted communications) and then queries a secure database to verify the ID is valid. The chip's power comes from the RFID interrogation signal.

What if the chip is kept intact and the components are changed. The chip won't know whether a particular componenet has been replaced by a counterfeit one after the board comes out from the factory.

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.
