I always hear a lot about how RFID will save the world.  But, this is news to me.

"The RFDump software allows a user equipped with an RFID reader, a laptop or PDA, and a power supply to rewrite the data stored in ISO 15693 tags, the most common tags used to host the EPC (Electronic Product Code) information traditionally stored in bar codes."

The assumption is that the military will have the budget to buy tamperproof tags. But not so for retailers and manufacturers, who will likely try to scrimp, Grunwald said. The most common EPC tags store the item information in cleartext inside the tag, and allow rewriting of the data. Each tag sits idle until powered on by the RF energy emitted from the gate, and can then be read."

Watch out, Walmart!
