3. EE/CS 480 Fall 2007 3September, 2007 University of Portland School of Engineering Project Puffin will improve 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

8. EE/CS 480 Fall 2007 8September, 2007 University of Portland School of Engineering Concerns/Issues Finding a compatible Keypad –Non-Matrix Keypad required –Separate bus for each key Programming CPLD –No team experience in programming such devices All possible tests were properly performed on logic before MOSIS submission Solutions –Create our own using button switches Not as professional looking, but still adequately displays the potential of our circuit in our MOSIS chip –Seek help from Golden Eagle –If MOSIS does not work the CPLD will October
