The book chosen, RFID ESSENTIALS, describes the basic structure of microchips and how they work. The first article, Big Data: Accumulation and Enclosure, about the Obama administration and microchips, emphasizes how people react to the idea of microchips and how they can be used. The other article, Resisting Surveillance: Identity and Implantable Microchips, also focuses on the reaction people have to microchips. The earlier sources can be used to show how pet owners and US citizens reacted to microchips.

How recent are these fears of microchips? Was the Obama fear the latest?
