RF Cafe Video for Engineers - Electronic PickpocketingRFID, near-field communications (NFC), magnetic strips, movement-tracking radars in grocery and department stores, all are systems designed to facilitate efficient merchandizing. Even when used legally, many aspects of the science are cause for concern from a privacy perspective. Visions of Orwell's Big Brother immediately come to mind, where an overarching, omnipresent government monitors and controls the movement of society's pawns... er, citizens. Distributors and users of the sensor products (RFID, NFC tags) and tracking systems range in complicity from useful idiots (sorry, but that's a well-defined term from the Stalinist crowd) to prosecutable criminals. The overwhelming majority - myself included - are part of the former. Marketing RF Cafe- RFID-Blocking Walletfirms, government entities, and street vermin make up the latter. This video, produced by TV station WREG, in Memphis, TN, is yet another demonstration of how much easier it is getting for someone to abscond with your personal data simply by being able to get within a fairly small proximity of you. Your wallet never needs to leave your pocket or purse. Some stores and office building have been reported to host systems that attempt to read tags sewn into clothing or imbedded in other items, along RF Cafe - Tin Foilwith detecting (but supposedly not reading) credit card types, and other forms of scannable ID, in order to determine your shopping and travel habits. The OnStar system in your vehicle, security cameras on every street corner, in every parking lot, and toll booth RF Cafe - RFID-Blocking Passport Case(with the help of facial recognition software), and even credit card purchase transactions routinely collect and distribute (usually for a price) information on where you were, what you did, and when you did it. Such data is routinely used RF Cafe - Groucho Marx Glassesas part of prosecution - and sometimes defense - in court. The good news is that there are products available that help to protect you from prying electronic eyes, and for not a lot of money. Think of it as another tax you must pay for your privacy. Question: How many of the people in the video do you think went out and bought a shielded wallet? My guess is none.

This video is no longer available anywhere.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
