Still some debate about the exact impact, the most safe version is Fingervein, but this is less "easy" to use. So trade-off between ease of use vs. security. Expect multiple techniques will be used depending on safety, money at risk, etc.
Hacker Jan "Starbug" Krisller cloned the thumbprint of the German Defence Minister Ursula von der Leyen after photographing her hand at a press conference. During a presentation at the annual Chaos Computer Club hacker conference in Hamburg, Krisller explained how he used commercial fingerprint software from Verifinger to map out the contours of the minister's thumbprint from the hi-res image taken using a telephoto lens. Krisller previous credits include successfully defeating Apple's TouchID fingerprint lock. Using a "raised ink" printing process, it’s possible to print an image on a very thin plastic surface, such as the skin of a balloon. By wearing the balloon skin over a finger, anyone can then assume the identity associated with the lifted fingerprint.
