well Rupesh, The material used to make the particles defines the Coercivity see below of the stripe. Standard low coercivity stripes use iron oxide as the material to make the particles, high coercivity stripes are made from other materials like barium ferrite. These materials are mixed with a resin to form a uniform slurry which is then coated onto a substrate. In the case of a credit card
on a card.Typically we think of our credit or bank card but there are other sizes and materials used for different applications. The card can be made of plastic polyester, pvc, or some other material or paper, or even some amalgamation of materials.The common point is that the card is used to provide "access" to something and it includes some form of automatic identification and data capture

novel properties. It is creating a set of tools and processes that will enable the synthesis of materials and structures at the atomic level. Nanotechnology makes it possible to arrange atoms or "chip.". Traditionally, circuits have been etched onto chips by removing material in small regions. However, it is also possible in theory to build chips up, one atom at a time, to obtain
refractive index of 1.5, which means that light travels at 1 / 1.5 = 0.67 times the speed in air or vacuum. Two common properties of glass and other transparent materials are directly related to their refractive index. First, light rays change direction when they cross the interface from air to the material, an effect that is used in lenses and glasses. Second, light reflects partially from surfaces
Hi ..ask your question on http://meracareerguide.com /AQHome.aspx It is amazing...nice forum !! Live counseling too !! I liked it so thought of sharing it !!
