– Our group will be explaining the physics behind mag stripes using Faraday\u2019s Law and the principles of induced magnetic fields, induced current, and induced Electromotive Force. We will attempt to explain the complex mechanisms in a fairly simple way.<\/p>\n

– In the experimental part of our project, we will be swiping vcards at varying velocities using different types of data storage (swiping for building access and swiping for food). We will record the minimum and maximum swipe velocities that are accepted by the card readers. Because we won\u2019t be able to determine the various speeds by eye, we will have to use Logger Pro to do that.<\/p>\n

-We will also explore the difference between magstripes on different types of cards (subway cards, credit cards, vcards etc.) and how different data is stored on the magnetic stripe. We will attempt to contact the card office on campus to see the process in which our ID cards are created<\/p>\n

-There aren\u2019t necessarily certain outcomes because our project is mostly theoretical, and it\u2019s just explaining a mechanism that\u2019s already known extensively. We do not have any expectations for what swiping speeds will be accepted by the card readers on campus.<\/p>\n
