Introduction The goal of this project is to create a reverse recipe system using RFID tags System will detect items in a given space Provides drink recipes according to currently available liquors

Market Analysis Need for faster and more efficient inventory control in: • Home Similar systems can be used throughout kitchen Laundry sorting • Bars & Restaurants Inventory management

Market Analysis Expected spending on RFID systems in retail stores expected to be $1. 3 B in 2008 [1] Few home appliances with RFID on market currently • Uses in stores will lead to uses in the home Consumers could be refrigerator manufacturers, kitchen designers, or the endusers [1] rfidjournal. com

Literature Survey Hurdles RFID systems must overcome: • User acceptance Occurs when tags benefits outweigh risks • Reliability Solved by increased coordination between readers • Cost 5 cent tags [1] • Security Altered random access [2] [1] “A 5 Cent Breakthrough", RFID Journal [2] “An approach to security and privacy of RFID system for supply chain”, In E-Commerce Technology for Dynamic E-Business

Literature Survey Primary components of RFID system: • Transponder (tag) • Transceiver (reader) • Data Collection Device (computer) RFID Middleware works between the transceiver and computer [1] RFID middleware design: addressing application requirements and RFID constraints”, In Proceedings of the 2005 joint conference on Smart objects and ambient intelligence: innovative context-aware services: usages and technologies

Requirements Analysis Operating Environment • Microsoft. NET framework 2. 0 • Microsoft Windows • SQL Server 2005 Express Environmental Constraints • Human Factors User Interfaces

Requirements Analysis cont. Communication Interfaces • USB/Serial/Ethernet/etc. connection with RFID reader • PC internet connectivity Hardware Interfaces • Mouse, keyboard, screen, etc.

Requirements Analysis cont. Performance Requirements • Reasonably fast response Evaluation Metrics • RFID scan and report time • Database access time • Recipe search complexity

Schedule of Development

Approach 3 main components • Database SQL Express • Program code C#. NET • Sensor Passive RFID reader

Costs Hardware • RFID sensor • PC ~$200 >$400 Software • Visual Studio Express ~$500 Program Time • ~400 man-hours total ~$300, 000 TOTAL ~$301, 100

Prototype Goals and Objectives Robust User Interface • Easy to use Inventory system • Database backed • Tracks items’ quantity and shelf life Recipe handling • Finds and presents recipes matching with inventory • Allow manual recipe input/deletion

Future Goals RFID tracking system integration • Reliable scans • Easily communicates with system Support and reporting • Error logging • Additional testing • Internet options Downloadable recipes
