How do you make that assumption? Apple can be let off because they stick it in the home button and it's a press scanner as opposed to a swipe one? Yet they BOTH do the same task.
No, Apple copied the idea from Motorola straight up who did it first and by several months I might add.
I don't make ANY assumptions. I'm speaking factually.
Apple's TouchID is fundamentally a different technology than the Atrix scanner. One is capacitive, the other is optical.
That's like telling me that inventor of the smartphone copied the traditional landline because they are used to do the same task. The truth is one is far better than the other.
TouchID isn't a "push scanner" either......you lay your finger on it, the ring around the button detects the presence of a finger, the sensor reads the print.
Now they both may have the same overall function (to unlock your device using your finger) - but the REASONS for implementing this tech and the actual IMPLEMENTATION of the tech are just as important if not more so.
So I slap a crappy fingerprint sensor in a phone. Am I copying anyone if the damn thing doesn't ever work? The reason Apple implemented TouchID was to securely bypass entering passwords dozens of times a day. This isn't an assumption - beside the fact they said this themselves, you can see this in the implementation. It is designed to be fast, reliable and secure.
Samsung slaps a fingerprint sensor that doesn't work as well. Were they doing it to also bypass passwords? Well if that were the case, you'd think they'd implement it in a way that would be faster than entering your password - not slower or less reliable.
As for the Atrix - what was their goal? To use the fingerprint as a means of securely locking a device. Speed and convenience don't seem to be big concerns as the sensor used is the less reliable optical scanner which works sporadically and involves a swipe. The placement is also less convenient.
You can try to simplify things all you want - truth is, if you actually think and look at what has gone into each iteration, you'll see Apple did things differently. Hence why its become a big hot button for other OEMs and why its so successful for Apple.
