Fingerprint I.D. chips

Posted by michael on from the got-your-number dept.

An AC sent in this: "AuthenTec's scan gathers information from radio frequency signals bounced down to a live layer of skin. Those signals return to the fingertip-size chip where a tiny array of antennas take the feedback and chart out peaks and valleys, yielding a three-dimensional "sculpture" of even the faintest fingerprint."

  1. This is cool. :-) by tzanger · · Score: 3

    I have been designing systems with this chip for several months now. Except for their damn standalone modules which don't have the CTRL_OUT/ signal routed to the pin these chips are Very cool. They make a smaller USB version as well.

    The even cooler part is that their standalone module uses a DSP and external Flash -- you can read out their templating algorithms and use them in other systems!
