We saw a fingerprint identification login system at Ocean Basket today. Next time you are there watch the till / point of sale (POS) area and see how the staff login to the computer and enter details of what you ordered, and then again to print the bill. If they have dirty fingers they just wipe them on their pants, and with their clean fingers login. I believe the touch screen may get dirty but clean fingers are necessary for identification. We may be moving to the controls mentioned in the book and movie '1984' but I think it such a clever idea.
