2.  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.

3.  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)

5.  Environmental Impact Analysis Three Life-Cycle Stages  Manufacture  Normal Use  Disposal/Recycling  Ethical Challenges Customer’s credit card information Keeping track of spending habits

6.  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*

7.  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

8.  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.

9.  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
