    The resolution seems to be still 508 dpi, but looks like it is not a square chip: 112x96 pixels (I am unsure if I'm still able to properly count pixels, that's weird numbers...), so a little bit better than the previous version.

It seems that dry fingers are still a problem...

  • So there is the Validity chip on a flex -as usual-, but this time there are balls to go to the upper part of the button: it is likely that the conductive lines are directly done on the inside part of the button. I wonder about the number of "pixels", because the number of balls is pretty low, so likely a not so good resolution...
