No it's not overkill, and no, fingerprints are not 2D. The fingerprint scanners on iPhones (and I believe other phones as well) are capacitive, meaning they rely on the physical ridges in your fingerprint.
- tantalor 10y agoFingerprints aren't 2D, but the sensor is. The sensor does not directly measure the height of the epidermal ridges. Rather, the varying thickness of the epidermic vary the dielectric between the conductive dermis and sensor. So you can replace the ridges with something completely 2 dimensional but with the same dialectic pattern. A normal home printer ought to be able to do that.

- lawl 10y agoindeed the iphone fingerprint does check if the objects are capacitive though, but that's a separate check. the "scan" is still just iirc. a infrared 2d cam cough graphite powder cough
