Barcodes are yesterdays news anyway, they'll be slowly phased out with the introduction of RFID chips.
Being English I'll use english examples here but for instance, right from the TEsco website, here is some info in how one of our largest (if not the
largest) supermarkets is introducing RFID ships:
And I know Asda is owned by Walmart, so they are probably using them now.
They are becoming cheaper and cheaper and it won't be long before they will have completely replaced the standard barcode.
The new passports and ID cards will have them in. Though they are being labeled as contactless chips/cards etc.
Here is a company that sells passport readers, they all have contactless readers built in now as well:
There are different standards, the insecure one that most people think of are the 125khz tags that go mainly in animals, car keys, the Verichip, etc.
These are insecure and only transmit a 'word'.
The 13.56Mhz variety can be more secure and hold more information. They are the ones that seem to be used in retail tagging as well as in passports,
ID cards, etc. They are basically like a contactless smartcard such as the one that goes in your Sky box. And seeing as no-one appears to be able to
hack the new Sky cards, they are pretty secure if they are set up correctly.
You also have to be within a couple of inches to read them.
You can pick up a 13.56Mhz reader for your PocketPC for about £150 at the mo, so it's easily affordable for your own experimentation.
If you can find 666 hidden in every tag then maybe there is something to it, but I'm afraid in my opinion finding something in an old redundant
technology that is going to be phased out seems irrelevant.
I thought that 666 was meant to mean man as god anyway, but I guess that was just another opinion that I read somewhere.
If you type '666 man as god' in google a few sites come up. The one I first read a couple years back was this one I think:
Looking at it that way, I believe that have the mark of '666 - man as god' would encompass anything man made that is used to rule over other humans
with a godly hand. The omniprescence of Big Brother, the ability to track your every movement, transaction, goods purchased, people visited, etc etc.
