The issue is bigger than just the new style of passports, which contain chips that emit information that can be read by a scanner. We're also talking about your Metro SmarTrip card, your employee ID/building access card, your automatic highway toll pass, the newest wave of credit cards and gas purchasing cards, even digital drivers' licenses being developed in some states.

In addition, some privacy advocates fear that criminals could steal someone's personal data simply by scanning the person with a chip reader. “There's been quite a few demonstrations of vulnerabilities in RFID technology,” said Mike Aiello, an information security specialist for a New York City investment bank. Aiello has launched a business called DIFRWear, which makes wallets that block RFID signals to prevent unauthorized viewing of credit card data.

The adage &ldquoJust because you're paranoid doesn't mean they're not out to get you” seems to be the motivating idea behind the line of wallets and passport holders from DIFRWear, in New York City.

The market for those transmission-blocking sleeves is based on fears that the information stored on ID chips in new U.S. passports can be intercepted by using RFID-ready technology.

A company named DIFRwear (RFID spelled backward) has sold about 10,000 covers since it started production just over a year ago.

RFID (radio-frequency identification) chips can now be found in many credit cards, student IDs and, as of October 2006, all new and renewed U.S. Passports. To prevent identity thieves from reading the personal information stored in these chips, these soft leather passport holders contain a layer of RF shielding to protect information stored within.

Many people don't realize that new U.S. passports have RFID technology with weak encryption that makes the data on the chip easy to read with the proper reader device.

If you're concerned about your RFID-chipped credit cards being skimmed, you might want to consider shielding them. DIFRwear makes a wallet with the shielding already included.

I've been traveling more than usual lately and this does require me to carry a passport for airport security (TSA), a credit card for the hotel (even though I pay cash), and a driver's license for renting a car. Thus, the time had come to get some protection for the RFID chips: [from DIFRWear] an RFID-blocking passport case. My passport goes on the left. On the right are four slots for my single credit card, my AAA card, my driver's license and my business cards.

With RFID tags in Credit Cards, Passports, and drivers licenses coming out I started to worry. Soon there will be RFID tags in money. I guess that would help solve some of the poverty problems. RFID tags are also not very secure. When the first RFID passports came out in the UK the encryption on the chips was broken in under 48 hours! RFID blocking wallets are for sale for around $20.
