An introduction to the types of biometrics currently out there, how they work with side charts informing how invasive they are to record, how secure they are, and potential drawbacks.

What a fascinating read! This was very well done in layout and language used. It breaks down the science in easy to understand terms concisely. And it covers an array of common and not so common ways we can use physical traits and actions of our bodies to identify people. I had heard of some of these but definitely not all of them. Kids love spy stuff and much of this is the kind of equipment used in those spy stories (and also in everyday real life too…which the book does point out). This should be a huge hit with curious kid and tweens. And it would make a great filler read aloud for science classes that have just a little extra time. Definitely need to add a copy or two of this book to the library when it comes out.

I enjoyed this book, it was full of facts and useful information and I did learn from it too! Entertaining and great as an introduction to Biometrics

Fabulous introduction on biometrics for middle and high school readers! The language, layout, and illustrations are all age-appropriate, complement the content, and will even draw the interest of reluctant readers. Each set of pages about a different biometric has a similar format, so it's easy to follow and to find specific kinds of facts (e.g., how it's collected, how secure it is, examples of current use, etc.).

This book is both an enjoyable and informative read for middle and high school readers. It's even an enjoyable and informative quick read for adults! The author also includes a page of selected sources in the back of the book, which may be valuable for teachers, curious students, and students writing reports on this subject. I highly recommend this book for libraries that serve middle and high school students!
