Ethical and Environmental Impact Analysis (Left to Right) Matt Finn Brian Crone Samuel Oshin Yonatan Feleke
Project Overview • Future Cash Register • The future cash register is a point of sale box designed to make wireless transactions through the use of Near Field Communications protocol. • It will accept payments and send receipts through NFC. It will also aide the cashier with orders through voice recognition.
Project-Specific Success Criteria Ability to customize the inventory via the user interface (Atom) Ability to communicate with an NFC device (dSPIC30) Ability to interface with an IR sensor to detect the presence of a user (dSPIC30) Ability to display prompts to user through LCD (dSPIC30) Ability to aid cashier by highlighting menu choices while placing order with voice recognition (Atom)
Outline • Environmental Impact Analysis • Three Life-Cycle Stages • Manufacture • Normal Use • Disposal/Recycling • Ethical Challenges • Customer’s credit card information • Keeping track of spending habits
EIA - Manufacturing • LCD Screens • Companies used to use Nitrogen Trifluoride (NF3) in manufacturing (circa 2008). • Manufacturing processes have since tweaked their production lines to use Fluorine instead. • Micro • Microchip is a “Certified Green Partner” • *Don’t eat any of the components*
EIA – Normal Use • Power Consumption • Atom Board • Power Supply Output: 12V, 5A => 60W • Efficiency Level V: (min 87% efficient) • 60 / .87 = 69W • Touch Screen • 48W • PCB • Power Supply Input: 8V, .18A => 1.44W • TOTAL: ~119W
EIA – Disposal/Recycling • Atom Board • EPA recommends finding a local recycling program (E-cycle St. Louis, B.W. Recycling) • PCB • B.W. Recycling buys PCBs (100+ units) • Touch Screen • Planar offers “Environmental Initiatives” for disposing of their products. It usually involves sending the product to the State’s recycling program.
Ethical Challenges • Handling User’s Credit Card Info • All credit card information is AES encrypted once our system receives it • Range of NFC is only a few decimeters, difficult to intercept • Handling User Purchasing trends • Keeping track of a user’s purchases via their credit card and selling this info in the “Big Data” market
