The rumours reached fever pitch when a false story came out that Samsung had bought Fingerprint Cards, a story which is now the subject of an official fraud investigation.
Carlstrom told Reuters that he "expects" Samsung to launch one or possibly two phones with swipe or touch fingerprint sensors next year, adding that "our goal is to be selected as one of their sensor suppliers in 2014".
That's despite word from an anonymous Samsung official who said in September that the company is "not yet developing the technology" for mobile fingerprint scanning.
What's more, it's strange that Carlstrom would even mention Samsung after buyout rumours from October, particularly when his company is still suspected of - and co-operating in an investigation about - falsely spreading the Samsung acquisition story to boost its own shares.
Plenty of fish
The company isn't putting all its eggs in Samsung's basket, hinting that it is also in talks with other smartphone makers including LG and Huawei.
Fingerprint is walking the walk as well as talking the talk, forecasting that it will make five times more money in 2014 than it did this year.
Carlstrom also revealed that Apple considered buying Fingerprint when it was shopping for a sensor supplier back in 2010 - it ended up opting for Authentec instead, which formed the basis of its TouchID tech.
While it's interesting to hear the viewpoint of a clearly outspoken industry insider, it's also worth bearing in mind Carlstrom's bias - after all, the CEO of a fingerprint scanning company is hardly going to come out with, "Yeah, fingerprint scanning's not that great really. I doubt it'll take off."
