Benefits of Smart Cards

I went to a shopping mall in town, shopped for the grocery I needed and went to the counter, only to realize that I had forgotten to carry hard cash! I panicked for a moment, but then calmed myself, as I was relieved to find my credit card in my bag. I quickly paid the bill and left. I was happy that I had my card with me. I began calling it a ‘smart card’ since then. It was years later that I came to know that these cards are in fact known as smart cards. I soon realized that I had been harnessing the smart card technology all these years and experiencing its benefits too!

A smart card is no small wonder, although it might seem to be. It is a pocket-sized memory chip that is embedded with integrated circuits. Its chip comprises memory and a microprocessor. The present-day cards have a 32-bit RISC processor, which helps in processing of the information stored on the card. A card reader configured to accept data from that card can read the information stored on a smart card. It is needless to say, that smart card technology is popularly used today. They are used as identity cards in educational institutions and workplaces. They can be used to store vehicle registration information or can be tagged to products/goods to store vendor-specific information. They are widely used as credit and debit cards where they enable us to perform financial transactions without the use of paper currency. Let us now turn to the advantages of smart cards.

Benefits of Smart Cards

One of the most obvious benefits of smart cards is that it is always safer to carry a single card than bundles of green bucks. Moreover, the purchase of goods, payment of bills and other bank transactions can be performed easily and speedily with the use of smart cards.

Another important benefit of smart cards is their inbuilt security. They offer protection of information that is stored on them. The smart card technology offers transaction security. Each card has a unique serial number of its own and is capable of performing encryption, thus reassuring secure transactions. Modern-day smart cards have a chip operating system, which possesses error-checking capabilities and user authentication facilities.

A significant advantage of smart cards is that they can, not only store data, but also process information. Through smart card readers, one can communicate with other computing devices. Moreover, smart cards are electrically erasable because of which they can be modified. It is possible to update information stored on the card without having to issue a new one.

Probably, the most important benefit of smart cards is their portability. Owing to their small size, they can be easily carried along. Their communication with the readers is wireless, thus makes it easy to use. Owing to their portability and wireless capabilities, the smart card technology can be implemented in remote areas where wired online communication is not possible. Due to the ease of use and high transaction speeds offered by them, the elderly, the disabled and the socially deprived can achieve improved access to resources and services.

Smart cards find applications in a wide variety of fields. They are convenient to carry and easy to use. They assure protection of data stored on them and offer user authentication facilities. The secret of their popularity lies in the manifold benefits they offer. Sure, they are here to stay!
