When pulled apart, sticky tape generates electromagnetic waves through simple friction. Now, as reported this week in the journal Nature, UCLA's Carlos Camara and Juan Escobar have discovered that in a vacuum, sticky tape also sends out strong enough x-rays to image your finger. Check out their bizarre sticky tape unpeeler, and see the machine take an actual x-ray image of a finger.
A number of credit card companies now issue credit cards with embedded RFIDs (radio frequency ID tags), with promises of enhanced security and speedy transactions.
But 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.
This episode is part of our ongoing series of interviews with some of the thinkers, hackers, and tinkerers at the O'Reilly Emerging Technology conference this year.
