What Is A Smart Card?
Smart Cards are a diverse form of data storage, past the physical attributes of the plastic and chips on a card. The digital information on a card is digitized and encrypted within its own parameters. They have integrated circuits, or IC's within the chipsets, and can be used across most industries. Already, most nations use SIM cards, chip-based ID Cards, Driving Licenses, and many others; these are all different permutations of the components of a Smart Card.
Simply put, a Smart Card is a plastic card with a form of data embedding (Chipsets, Magnetic stripes, printing etc.) that has the ability to store, use, and process information when interacting with its digital counterpart; for example, a Credit Card has information stored on it about one's bank details, and creates an electronic infrastructure when interacting with a card machine, by using a card to initiate a process inter-bank.
Smart Cards have numerous advantages, such as security, convenience, portability, accessibility, and cost-advantages, amongst a plethora of others. It can be used to identify, authenticate, store, leverage large volumes of information, process and many other digital applications. They are a vital constituent of a constantly expanding digital infrastructure, and will be the future of the digital world by bridging the physical and tangible, to the digital clouds. This is already resonating around the developed world, ranging from the Octopus Card system in Hong Kong, to the Digital ID retinal information within the ID cards in The Netherlands to the 4G network's SIM Cards within the USA.
