Walmart piloted RFID technology for inventory in Dallas and WFAA covered a protest against them.

The first barcodes were on train cars to track them along the routes. It is fast and efficient. I love machine readable code. In fact, back in the late 90's my team created the first consumer barcode reader for reading UPC codes of products and taking them to Internet web sites.
When I found out there was a protest at a Dallas Walmart in October 2005 that was piloting RFID technology that they were using for pallets, I decided I too would PRO-test. That's show up and talk about the PROs of RFID... I created signs to promote the technology and was the only "marcher" in the for vs against category.
It got a bit too religious with the other marchers, but the story unfold in a way I could never predict... My old host on TXCN, where I previously had a technology segment for years came out to do a story for WFAA on the protesters and said "thank God you're here to breath some sense into this story." It was a good laugh for me, and RFID and other wireless technologies haven't slowed their march.
