 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)

 dsPIC30F5011 Architecture: 16-bit CPU Speed (MIPS): 30 Memory Type: Flash Program Memory (KB): 66 RAM Bytes: 4,096 Operating Voltage Range: (V) 2.5 to 5.5 I/O Pins: 52 Pin Count: 64 Internal Oscillator: 7.37 MHz, 512 kHz Digital Communication Peripherals: 2-UART, 2-SPI, 1-I2C Analog Peripherals 1-A/D 16x (ksps) Timers 5 x 16-bit 2 x 32-bit

 Split into 3 parts Atom Microcontroller Tester

 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
