i had an idea if you put very slim rfid tag on a bullet cartridge and a rfid reader in a gun, maybe we can finally create a ammo counter?

Other uses that come to mind are the tracking/monitoring of how food packaging is discarded. So if packaging is discarded incorrectly (not recycled) a waste management company can easily identify what items can be recycled in a pile of garbage... or use the technology to understand the origin of packaging when it has been disposed irresponsibly - like on the side of the road. As garbage is picked up, the RFID tag will carry who purchased the item and from where...

If the range of 300 meters is achievable, maybe everything that ever gets stolen (computers, cameras, solar panels) can be found and the criminals can be shot (or put in jail. Shooting would be better.)

Not really one that usually goes down the \"stop, I need my privacy\" road, but this just begs to be abused.
300 meter range. Ok, just drive down the street with an RFID reader to determine what products are in every house in a neighborhood. Less than 5 minutes and the uses are endless!
Targeted advertising, drive down the street dropping flyers in mailboxes based on existing products in houses - determined and printed in real-time. Example: if a house has a pregnency test in it drop off an ad for diapers. Imagine the parents surprise, and what the teen girl will say!
Check for possible criminals. Drive down the street \"looking\" for guns. A house has a lot of them and a crime has been committed with a gun nearby lately? Get a warrant and search for evidence! After all, the witness said the suspect was wearing a leather jacket and the RFID scan shows a leather jacket in the house. Oh, get one for these other four houses while you are at it, they have leather jackets too.
Looking for a new TV or a way to make a quick buck? Drive through a neighborhood and see what is \"available.\" A short drive and you will know what house to hit up for products. Nope, no security system was bought, and both adults clothes are of a \"business\" nature so there should be nobody around when you come by mid-morning. No pet food detected, and kids clothes were sized for Junior High. Low risk, and you have picked that brand of door lock and safe before with no problems.
On the bright side, it should be easy to figure out which neighbor has your ladder!

@CeridianMN, privacy is one major concern. One would have to figure out if the tags could be disabled. The shopping for things to steal is no different than driving around on garbage day. These tags would be printed/installed on packaging. Just be careful not to put all your fancy expensive TV and electronic boxes out on the curve and no one should suspect you have anything above the rest worth stealing.

\"More advanced versions could even collect all the information about the contents of a store in an instant, letting a retailer know where every package is at any time.\"
I just saw a news report on the news a few hours ago about some Portuguese company that developed such a system. The system knew how many products were on a shelf and could also give a warning when items were misplaced.
I assumed this was all done via RFID although they didn\'t specify.
Can\'t remember the name of the system or company though...

I don\'t live my life worrying about being watched by the government . BUT ever since 911 we have lost more and more of our personal rights then ever before in history . The paranoid populas say well as long as it makes us safer . This new packaging gives them one more way to watch . California.....OBD111 , Drivers Licences.....transmit everything , Passports..... Transmit everything , Credit Cards.....Transmit Everything . When is everyone going to wake up and say no more ? When they finally have us all Chipped so they know were we are at all times ?

What this doesn\'t address is in almost every grocery cart there are many articles with no packaging. Think of Bananas, apples and almost all other produce.
Similarly anything sold in bulk doesn\'t have a label a package just a bag on which you attach a label with a number. The bag has to be weighed before it can be priced.
This kind of unthinking article spoils the excellent job you normally do.

There would be no privacy issue with the RFID tags themselves. It would simply transmit a code to the receiver. The privacy violation would occur when the database is stolen from the retailer, etc. Without the database specifying what each tag is attached to, the tags have no useable data. On the other hand....you could get an RFID reader and make your own database of the tags on items you purchased. Then you could find your stolen items, find which neighbor borrowed your ladder, find your missing sock....IOW, you must know what each tag is attached to, or you have no useable info. If you\'re really paranoid....microwave your items for a second or two, and it\'s toast.

The big brother society is upon us disguised as the nanny society, \"because it\'s for everyone\'s good\". The majority of the immigrants we having coming to the USA these days come from a hierarchical society where the government is the ultimate power with divine right. The more this happens the closer we get to a revolution, ya people will just right that off as paranoia but it\'s coming.
The government is starting by imposing a health care system on us they we don\'t want, they don\'t care it\'s just a way to start controlling us.
