The bill, which California lawmakers believe is the first of its kind in the nation, would prohibit the use of radio-frequency identification, or RFID, chips in state identity documents such as student badges, driver’s licenses, medical cards and state employee cards. The bill allows for
some exceptions.
RFID, also known as contactless integrated circuits, transmits information wirelessly, allowing scanners to read cards from a distance, typically a few feet. The technology is widely used in building security and inventory-tracking systems, and is being considered for numerous other applications.
The bill, which passed out of the state Senate Judiciary Committee on Tuesday with a vote of 6 to 1, also would outlaw skimming — which occurs when an unauthorized person with an electronic reading device surreptitiously reads the electronic information on an RFID chip without the knowledge of the person carrying or wearing the chip.

I assume, unfortunately, based on our political leaders initial embrace of the Matrix personal data mining scheme, that we will not be as wise in Wisconsin…
