wireless through the use of the NFC
technologies. It will accept payments and send
receipts through NFC. It will also aide the
cashier with ordering through voice recognition



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)
