I wonder if that will work in all lighting conditions and weather. Is it a system that will not be fooled by a photo? Fingerprints seem a more established technology and are possibly more reliable.

I am a bit wary of some of the keyless systems now. I do not see the issue with having to press a button to unlock the car. I do not necessarily want it to open just because I am nearby. I've heard that people need to put the fob in something that blocks the signal.

You would think that car security would be a solved problem, but they still get stolen.
