On today’s episode of Boing Boing tv, hacker and inventor Pablos Holman shows Xeni how you can use about $8 worth of gear bought on eBay to read personal data from those credit cards — cardholder name, credit card number, and whatever else your bank embeds in this manner.
Fears over data leaks from RFID-enabled cards aren’t new, and some argue they’re overblown — but this demo shows just how cheap and easy the “sniffing” can be.
Thus, RFID makes it easier to steal credit card info than before. No need to hack into a website or copy a card number at a restaurant, just read the RFID as the person walks by.
If you fear your RFID enabled whatever – credit/debit card, passport – will be hacked, toss it in the microwave for ten or fifteen seconds. There’s no way to determine what caused the RFID to fail… it just failed.
