This thread tells me none of you understand at all how this biometric tech works.

1st the health concerns:

Palm reading systems are most likely vein pattern readers. They do not need a surface to be touched and can read from about 6 inches away. Making them touch less.

Second the way these systems work, they scan a pattern assign a number to it and then when checking again they only verify the number. At no point do they store what your hand looks like. The storage for that would be massive and worthless. It makes no sense at all from a technical point.

And even less sense to sell as data. What they could make more money on is selling your account payment information in correlation to the where, when, and what you got. Which they can and most certainly already do. Because there are no laws saying they can't.
