EE/CS 480 Spring February 2008 University of Portland School of Engineering Overview Introduction Scorecard Additional Accomplishments Plans Issues/Concerns Conclusions

EE/CS 480 Spring February 2008 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

EE/CS 480 Spring February 2008 University of Portland School of Engineering Scorecard Previous Month’s plans –Complete programming of CPLD and integrate into demo circuit –Purchase buttons to build keypad device to integrate with the demo circuit Shortcomings –Final buttons not purchased

EE/CS 480 Spring February 2008 University of Portland School of Engineering Additional Accomplishments Pin Output received from MOSIS

EE/CS 480 Spring February 2008 University of Portland School of Engineering Plans List your team’s plans for next month –Test CPLD –Build Keypads for FULL test –Replace with MOSIS chip
