It should be no surprise that I'm no fan of RFID. Sounds like Walmart is learning the same lesson (the hard way).
Now you too can play with RFID in the privacy of your own home. Amaze your friends, win the school's science fair, harass your sleeping roommates. All with the RFID home kit. So strange I couldn't possibly be making this up.
And if that ain't weird enough for you, how about a RFID stapler?
See? That's why I stick to barcodes myself.
