RFID-enabled IC chip cards carried by over 90% of all salarymen


Hello Kitty Faraday cage for RFID-enabled cards

I feel RFID is greatly misunderstood, and deliberately misrepresented, by those with axes to grind regarding surveillance, as although the more usual passive type of RFID can technically be read from a few metres distance in ideal condition, it is very sensitive to interference from other metal items making random distance attacks infeasible. Just in case you are really paranoid, as pictured above, Kitty chan can protect you! To find out what the average Japanese does with their IC Chipped cards, JR Tokai Express Research Inc performed a survey on this very subject of IC Cards.


Over the 30th and 31st of January 2008 330 members of the JR Tokai Express Research monitor group employed in either the private or public sector completed an online survey. 78.8% were male, 9.1% in their twenties, 38.5% in their thirties, 36.1% in their forties, 11.8% in their fifties, and 4.2% in their sixties.

I have three chipped credit cards, with one of them doubling as an employee ID card, and an ICOCA train pass so I’m actually slightly below the average.
