Future Cash Register • The future cash register is a point of sale box

designed to make transactions completely

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)

Devloped in C#

6 Modules • GUI

• Restaurant/Menu class structure

• Voice Recognition

• Serial communication with micro

• Cryptography/Security

• Database backup

GUI • Ordering screen • Checkout/payment screen • Admin screen

Restaurant/Menu Class structure • Top level class: contains inventory, restaurant info,

and admin password • Inventory class: contains lists of menu items along

with lists of combo items • Menu Item class: contains item name, price,

description, keywords, possibly picture • Combo Item class: contains list of menu items

included in combo, name, keyword, and price

Voice Recognition • Uses System.Speech.Recognition namespace

Serial Communication • Uses SerialPort class from System.IO.Ports

namespace

Cryptography/Security • Uses System.Security.Cryptography namespace

• Possibly AES

• Will encrypt before storing onto hard drive

Database - managed on SQL server

Micro Controller: • Poll infrared

To identify if customer is near

• Send a “Go” signal

Through UART to COM port.

• Wait for “Pay” signal

• Send to LCD

Place NFC close to red circle

Micro Controller • Poll NFC until not empty

Read through SPI

• Send a “Pay” Signal

With Credit Card Credentials

• Wait for “Receipt” Signal

Store Receipt to Ram

• Write to NFC FIFO Manager

Send Through SPI to NFC
