Re:For real - what's the big deal with these? (Score 1)

I can imagine some uses that would be an invasion of privacy:

• Some kids put together a reader and start scanning people going by. "Oooh, she's wearing thong panties...".
• Some crooks use a reader to scan people or cars for expensive items to steal.
• Stores scan you as you come in to determine what kind of things you're wearing, or items you are carying. Clerks use this information to determine if you are a customer worth servicing.
