Don't overreact. These are not the Diebold memos, it is just some woman who sent a non-funny joke back to the victim of the joke by accident. I don't see what the hubub is about. Granted, getting RFID awareness is good, but this story was a waste of time save for some of the info about RFID technology.
I hate sigs.
This story was covered in the Australian press a few days ago. Other sources report that the GMA has apologised, describing the acction as a "youthful indescretion".
a world in progress...
Batteries? Have you ever even read anything about RFID technology? They don't have batteries, which is the only reason for their limited range. They get power directly from the radio waves.
RFID tags in the packaging? They are now weaving them into of clothing, they are inside your tires, and in the handle of your razor.
Disable them? Try microwaving your tire...
The concern is that they don't deactivate themselves. And almost any RFID tag can be read by almost any RFID reader. So your boss can start checking how often you change your underwear, and indirectly can track you around the building by the tags in your clothing. Your car could be tracked at every intersection.
It's not that there is an inherent problem, it's just ripe for abuse, and big step towards slipping into a police state.
Most of us just don't want to get anywhere near there. There is most definitely a need for concern.

Anyhow exactly does my boss know it's MY underware?
Assuming your company set up an RFID reader at the entrance for any of a number of reasons, every RFID tag on your body would activate and broadcast it's serial number. That code would most likely contain a manufacturer code, a product code, and potentially a unique serial number.
At the end of teh day you walk back up through the scanner. Maybe they are checking to make sure you aren't trying to sneek out with tagged company property. Rountine proceedure would be to subtract the list of ID's you entered with from the list of ID's you are trying to leave with.
So, one day the computer alerts the security guard that you are trying to leave with an ID code taht you didn't have when you came in. The code number pops up and an automatic search is done on it. The computer comes back with two hits on the search. The first hit is a match on it's internal database - that ID came in this morning whith Sue from accounting. The external database hit reveals that manufacturer code code is for Victoria's Secret, product code Lowrise V-string panties, black, size 5.
Security Guard shouts out in front of everyone: "Hey Bob! Whatchya doing with Sue's panties? Are they in your pocket or are you wearing them?"
He could quite easily pull up your history of ID tags for the year and see what brand(s) of under wear you wear, how many different pair you have worn, and yes, he could easily see how often you wear the exact same pair two or more days in a row.
RFID tags are already being embetted in the fabric of some peices of clothing. As RFID becomes common situations like I described above can become quite common. That daily RFID scan can be analized for any number of reasons, and the data can be extensive and invasive.
Every single store you walk into could preform such a scan. Obviously the "intended" purpose is to make sure that you don't walk out with unpaid merchandise, but once they've done that done that then all of the data is already in the computer it can trivially be used for any purpose at all.
