I have been interested in RFID and found this book while doing a search at the local library. I am glad I did. Very good information concerning RFID and how it has been used and will be used in the future. Here are some excerpts of information that I find important:

From Chapter 2:

"What is RFID?

RFID makes it possible to identify and track just about any physical object you can think of—books, car tires, shoes, medicine bottles, clothing, pets, and even human beings.

The "RF" part of RFID stands for "radio frequency" and explains how RFID does its tracking: It uses electromagnetic energy in the form of radio waves to communicate information at a distance. These silent, invisible waves are similar to the radio waves that allow you to listen to your favorite FM radio station. And like other radio waves, they can travel right through windows, wood, and even walls....

One industry insider defines RFID as "any device that can be sensed at a distance by radio frequencies with few problems of obstruction or misorientation." This ability to transmit information through solid objects makes RFID far more invasive that the now-familiar bar code with its vertical black and white stripes. Bar code technology uses a laser beam to convey information, so an unobstructed path known as an "optical line of sight" is needed between the bar code and its reader. Since the bar code must be visible to the reader and its pattern must be clean and clear, its hard to read sa bar code someone's carrying without the person knowing about it. In contrast, items equeipped with RFID can be located and identified even when other things—like locked doors or sealed envelopes—are in the way."

I will have more excerpts...

I purchased another book from this author called "The Spychips Threat: Why Christians Should Resist RFID and Electronic Surveillance" on Christianbooks.com for my library. You can purchase your own copy here.
