    • WMU RFID Project, ECE 481 & 482 BlueGranite and Global Berry Farms Partner with WMU to Develop RFID System For Release: 1/28/04 KALAMAZOO, Michigan, 1/28/04 – BlueGranite, a Kalamazoo-based software development firm, has partnered with long-time client Global Berry Farms and Western Michigan University to develop a Radio Frequency Identification (RFID) pilot system to track flats of fresh berries from local growers, through cold storage, and to specific retail establishments. “In the near future, RFID technology will not only benefit our customers, who are beginning to request the use of these tags, but will also increase our internal efficiency while significantly enhancing our visibility throughout the supply chain,” states John Conner, Director of Information Systems for Global Berry Farms. Global Berry Farms is a LLC owned by Michigan Blueberry Growers in Grand Junction, MI, Hortifrut, S.A. in Santiago, Chile and Naturipe Berry Growers in Salinas, CA. Global Berry Farms is committed to meeting the needs of produce trade customers by consistently supplying all types of fresh berries year-round to North American and global markets, with innovation, service and dependability. The RFID pilot project will begin this quarter at WMU, when a group of engineering seniors develop and test a small-scale demo system under the supervision of electrical engineering professor Dr. Brad Bazuin. Upon completion of the first phase, a second group of WMU students will implement a RFID test environment at a MBG Marketing warehouse in Grand Junction. Once the production environment tests are complete, Global Berry Farms will conduct a market analysis of RFID tag costs and BlueGranite will assist with the implementation of the technology, ensuring that it integrates with Global Berry Farms’ existing accounting and warehouse management systems. 11 February 2004 7
    • Global Berry Farms RFID RFID System Specification Detailed Description The system shall use RF-ID technology consisting of RFID Tags, RF Readers with antennas, optional RF Writers, appropriate networked computer resources to identify and track product, and other supporting system components as required. System operation will require the attachment of an RFID Tag to the appropriate blueberry container when initially picked and packaged. The standard container for identification and tracking will be a cardboard packaging container or flat capable of holding a number of plastic clam-shell fruit containers. The standard flat or container will be of United States or European dimensions that will be stacked on a standard shipping pallet. … As a system goal, RFID identification and tracking should be to the plastic clam-shell container level. 11 February 2004 8
