Oh, this is a good one. If you’re not familiar with RFID tags, they are tiny chips (tiny as in they can be woven into fabric so that they are invisible to careful scrutiny) that can help provide information on an item that is easily scannable by computers from a short distance.
Now, the above statement is almost correct, except that “item” should be read as meaning anything (piece of clothes, box of cereal, your pet, you) and “short distance” should mean as far as someone is willing to build their scanner to read from (think 100+ feet possible).
Well, besides the privacy concerns, now it looks like the companies that use them have to be worried. An RFID tag could contain a virus that can infect their scanning systems and the databases they connect to, and this can be spread to other RFID tags.
