A few months ago I checked out a stack of books at our local library by placing the books on a kiosk. All 5 books magically appeared on the computer screen. Around the same time my father ran in the Bolder Boulder, a foot race of over 50,000 people. An electronic system kept track of his time and thousands of others by only having the runners wear paper race bibs. Pets that are found wandering can be identified and returned to their owners with a basic scan of the neck. How is all of this possible?
