An introduction to smartcard

advantages of smart card

Memory smart cards can be configured to be rechargeable or disposable, in which case they contain data that can only be used once or for a limited time before being updated or discarded. A smart card communicates with readers either via direct physical contact or using a short-range wireless connectivity standard such as RFID or NFC.

An introduction to smartcard

As banks enter competition in newly opened markets such as investment brokerages, they are securing transactions via smart cards at an increased rate. On this prototype, one can see how each leg of the microchip center is connected to the exterior world by a copper connector.

Distribution of smart cards in recent years has been driven by the payment card industry's move to support smart cards for the EMV payment card standard.

There is a rich ecosystem of suppliers and integrators for this standard.

Uses of smart card

Smart cards can also be categorized by their application, such as credit card, debit card, entitlement or other payment card, authentication token and so on. The cost of the smart chip technology was significant, which was why most of the corporations did not want to pay for it in the United States. Smart cards are now ubiquitous and have largely replaced magnetic stripe also known as "mag stripe" card technology, which only has a capacity of bytes of non-rewriteable memory and no processing capability. Commands, data and card status are transmitted over these physical contact points. Multifunction, microprocessor-based smart cards incorporate identity with access privileges and can also store value for use in various locations, such as cafeterias and stores. The two different chips may be used for different applications linked to a single smart card, as when the proximity chip is used for physical access to restricted areas while the contact smart card chip is used for single sign-on authentication. Those cards with microcontroller chips can perform on-card processing functions and can manipulate information in the chip's memory. Dual-interface cards are equipped with both contactless and contact interfaces. The United States has felt pushed to use the technology because of the increase in identity theft. VCC: Power supply. Note the thin gold bonding wires and the regular, rectangular digital-memory areas.

Smart cards capable of short-range wireless connectivity can also be used for contactless payment systems; they can also be used as tokens for multifactor authentication. Additional applications range from secure email to electronic commerce. Two-Factor Authentication insures protection of data and value across the internet.
