In a completely normal and unproblematic move, a school district in San Antonio, Texas has decided to insert wireless radiofrequency identification (RFID) chips into its student's ID cards so it can track the children at all times! It's OK, though, because this will help combat a problem the district has: it keeps losing children.

You would think that someone with artificial body parts would keep a pretty good record of what was stuck inside them. But apparently this isn't always case, so a New Jersey orthopedic surgeon is marketing a special RFID tag just for body parts, loaded with the vital data doctors might need down the road.

How do you justify paying for a swanky luxurious hotel that costs $200 a night? By stuffing your suitcase with as many hotel "souvenirs" as possible. Anything and everything from towels to shampoo bottles, toothbrushes, bath robes, slippers, etc. are applicable. Say hasta la vista to those klepto habits because hotels are beginning to track their towels with RFID chips.

Forever worried about evildoers stealing your credit card? A new kind of card that hides your account info unless you punch in a code is designed to put those fears to rest.
