Once again, Samsung tries to mimic a feature Apple introduced, and once again it is proven to be a mediocre alternative, rather than a forward-thinking innovation of an existing technology.
The problem here isn't that the fingerprint scanner was spoofed. Whitehat hackers proved they could potentially do the same thing with an iPhone 5s within 48 hours of its release. The problem here is that Samsung (and really Android as a whole) didn't have a security measure built in to help mitigate something like this. You can literally restart a Galaxy S5 over and over and over until you get it right. You can't do that with an iPhone.
This is what happens when your sole priority is beating a rival, rather than focusing on creating the best possible product for your customers.
But it's still awesome that you can link your fingerprint to your PayPal account on your phone now, right?
