Biometric data is intended to considerably reduce the risk of fraud while providing more convenience at the same time. The internet has many instructions on how fingerprints can be easily copied. It is just as easy to outsmart iris scanners – usually, a simple photo of the right size is enough. How secure are biometric payment systems really?
Fliehe: Biometric data make every person unique – and this makes them highly secure. But obviously, this requires high-quality products. They feature biodetection technology for example and can generally not be fooled with simple means like a photo. It's also clear that no process can guarantee 100 percent security. However, a 4-digit number that scammers can easily spot when you enter it at an automated teller machine, for instance, is far less safe compared to biometrics.
