Although some of the proprietary arguments are slightly overstated, Hayes makes a great point about how Wal-Mart's $2 per pallet non-RFID penalty reflects a lack of understanding of why suppliers have resisted RFID tagging. It's the software implementation costs and the fact that different retailers demand different versions. Hayes' column is worth reading. (But not everyone seems to agree. The RFID Journal took exception to the piece, on several levels. And then some RFID Journal readers took exception to that disagreement.)

Computerworld columnist Frank Hayes--a former colleague of mine from CMP and an awesome folk singer as well--has a wonderful column out about why the Wal-Mart RFID effort is still having problems.
