After all, it was reported that Samsung thinks that such technology is still in its infancy, and will require a fair amount of time to develop it further to achieve its full potential. There was also an unnamed Samsung official who was quoted as saying: “We never officially admitted that Samsung was weighing the fingerprint system and Knox for Galaxy Note 3 for security functions. We are not yet developing the technology.”
Another possible reason could be due to the fact that there is only a single company that develops fingerprint tech in Korea, and that is Crucialtec. Unfortunately, Crucialtec does not seem to have the ability to deliver the goods like Authentec, and it will require nearly a year before the semblance of a stable solution is possible.
