It is important not to overstate these findings:

(1) These are not real-world tests

(2) Fingerprint scanners can presumably get better over time

However, there are two big implications for fingerprints here. First, fingerprints are not inherently more secure than any other standard form of authentication (e.g., passwords). Second, fingerprints are inherently worse in one respect not mentioned here – you cannot change your fingerprint if it is compromised. What happens when there are services that require fingerprint authentication, and your fingerprint is stolen? The only reason you might not worry about this second point is if you believed that the first were not true (i.e., if you believed fingerprints were unhackable). This seems patently wrong.

Fingerprints are more convenient than other methods, and for things like unlocking your phone (assuming your banking app has an actual password), it is probably fine. For anything that requires actual security, though, biometrics are a terrible idea.
