(Wired) Just a few days after Apple unveiled its new iPhone with a fingerprint ID scanner, German researchers say they’ve cracked the scanner using a fake rubber print.

The researchers, with the Chaos Computer Club, posted a video on their website showing members of the group’s biometric team defeating Apple’s Touch ID with a fabricated fingerprint created from a photo of a print.

They photographed the print from a glass surface, laser-printed the fingerprint image on a transparency sheet, then smeared it with latex. A similar method was used in 2002 by researchers in Japan to demonstrate the security weaknesses of fingerprint scanners using a gel fingerprint.
