It’s interesting they use a fingerprint as an example of sending sensitive information. We’ve known for a long time that biometric data is terrible for authentication. Your biometric data will inevitably be copied by hackers. Once it is copied you cannot change it, ie. you can’t change your fingerprints.

The author sounds confused. We can already send ("teleport") fingerprints. This is just sending them via quantum entanglement, which I think is just a secure way that prevents interception. It sounds like the advance is to encode an image rather than just bits (and I assume it's not something trivial like just sending each pixel as a bunch of bits).
