Since its founding in 1976, Jams Stores have prided themselves in a wide product selection ranging from fresh produce, top of the line electronics, and quality house wares. With over 250 nationwide stores and thousands of products at each location, Jams Stores handles transactions numbering in the millions every year. In the past 10 years, an average of 18% of stores have reported incorrect input/output inventory cross checks yearly. In that same time period, 26% of stores have reported yearly inconsistencies of in- store inventory above 5% of their total inventory value. This has resulted in over $1.25 million in yearly loses for the company due to inventory problems. Growth projections for the company look positive in the coming years, and Jams Stores needs an innovative, efficient, and sustaining method of inventory tracking at each and every store. Without a solution to this problem the company will either be unable to continue growth at current rates or suffer growing losses every year. A possible solution to these problems that is both innovative and effective is the use of Radio Frequency Identification, or RFID. RFID tagging along our supply line would bring Jams stores to the forefront of technologically savvy retailers and create an efficient and cost effective method of inventory management. II. WHAT IS RFID ? Radio-frequency identification (RFID), is an automatic identification system. This system uses tags that store information about the product it is used for. The information stored in the tags have a varity of uses. These tags are used to identify and track objects using radio waves. History The history of RFID is very interesting because its initial intentions were quit different than their potential diverse uses. Even though it’s not completely clear when RFID technology was invented most sources agree that it was founded during World War II. Both the Allies and the Axis powers had trouble identifying their own planes and ships versus the enemies. Germans found a way to reflect radio waves as they were coming in to identify themselves. This is was the predecessor to what we know today as passive RFID tags i . Around the same time the British invented active RFID tags to identify Friend or Foe. They put transponders into plans and ships which gave off a signal to identify themselves 2 . This advance in technology led to many more inventions. Soon after, scientists discovered multiple uses for RFIDs and started to patient these ideas. Mario W. Cardullo was the first to get a patient for active RFID tags in the U.S. 2 . Charles Walton got a patient the same year for unlocking a door without a key. U.S used RFID to track nuclear material and the people around it in the 1970s. In the 1980 scientists found a way to pay toll automatically on roads by scanning transponders in the car. This was very efficient and is used all over the world today. RFID was not only used to track objects but also living things but putting RFID tags on cows. IBM engineers
