The word hologram is derived from the Greek words "holos" meaning whole and "gamma" meaning message-in other words, holograms depict whole message. Holograms appear to contain a three-dimensional image under proper illumination. They cannot be copied by ordinary means and hence are widely used to prevent counterfeiting of documents such as credit cards, driver's licenses, admission tickets and many other products
Today, the most popular use of holograms is in consumer products and advertising materials. Holograms are also important in various other areas of scientific research, medicine, commerce and industry. Holograms are also used on sports
trading cards. Hologram usage on credit cards, debit cards, I-cards, license etc. provide added security to minimize counterfeiting. 
Over the next twenty years the use of holograms will become more used among the public. The future technology that we envision will help with the construction and engineering of building projects as well as developing other machines and devices. It will help reduce both the time and funds that go into the design process of buildings and technology. This technology will also be able to show you if the structure of an object will do what it is suppose to without ever having to build it.
