http://www.hexus.net/content/item.php?item=5072RFID tags can be tiny; we're talking rice grain size, so in theory they could be anywhere and everywhere, which for some raises privacy concerns. Those concerns aside, however, what about viruses? How can a tiny device, the majority of which are passive, spread viruses?

I was at this BCS lecture about RFiDs last night, and i was talking to the guy there about this problem. We both agree this is media attention seaking bull ****.
Its not like people write RFID handling stuff in PHP, tokens are validated well just because of the inherient corruption that can occur with passive tags.
Active tags on the other hand frequently have a lot more memory and often provide info (GPS cords, temp, etc), now if someone had been really lazy, then its possible this could happen. Fact of the matter is people always need to input validate, regardless of if the inputs human or RFID!

these tags willl be fun. they are too simple to be secure in anyway...
"with a small number of companies now requiring staff to have on their person (sometimes even implanted) an RFID tag that grants them access to a secure area."
So find somone that has a tag, read it, and then program your own, and you can get anywhere in a secure building, like a bank
not at all silentdeath.
Most places that use rfid's for security use "ActiveTags" these can be thought of like the gold chip on credit cards.
some using "rolling codes" this means when an RFiD is scanned, its value is also chanaged. As such the cloning of a device becomes noticed swiftly.
