3. EE/CS 480 Fall 2007 3September, 2007 University of Portland School of Engineering Project Puffin will increase security of PIN input devices by exponentially increasing the number of possible PIN combinations. This is done through its use of chorded, synchronous inputs. This will benefit users of ATM’s and other Point of Sale (POS) devices by improving security while increasing pin combinations. Introduction
