Smart Cards

Smart Cards are an advanced evolution of the standard 'plastic cards' that are used for day-to-day transactions such as access cards and payment cards. Also known as Integrated Circuit Card or ICC, smart cards include a microchip or a simple memory chip embedded in the plastic body of the card. The card program resides in the embedded hardware and communicates with the external world through hardware devices called smart card readers for both read and writes operations with the card. Within the realm of smart cards, Tarang has specific expertise and specialization in Java Card development.

Java Card technology enables smart cards and other devices with very limited memory to run small applications, called applets, which employ Java technology at its core. It provides smart card manufacturers with a secure and interoperable execution platform that can store and update multiple applications on a single device. Java Card technology is also compatible with existing smart card standards.

Tarang's best practices in the Java Cards space will help your business reduces development costs, increases product differentiation, and enhances value to customers.


Smart Cards have a range of application in various industries:

  • SIM cards, used in cell phones on most wireless networks
  • Financial cards supporting both online and offline transactions
  • Government and health-care identity cards
  • Cards that provide logical access and physical access to enterprise resources
  • Biometric identification cards
  • Smart tickets for mass transit

On the majority of cellular telephone networks, a subscriber uses a smart card commonly called a SIM card to activate the telephone. The card authenticates the user and provides encryption keys for digital voice transmission. When fitted with Java Card technology, SIM cards can also provide transactional services such as remote banking and ticketing. Hundreds of millions of SIM cards based on Java Card technology are already powering innovative services in cell phones.

In the banking industry, smart cards give users secure access to a wide array of networked financial services including cash machines, bill paying, and bridge tolls. Java Card technology enables a single smart card to host multiple financial applications, and to deliver third-party services such as mileage programs or secure online trading.

Other applications are available in a wide variety, wherever security and authenticated identity are important, such as in controlling access to secure facilities and to medical records.

Java Card technology will enhance consumer access to new, e-commerce services through a range of connected appliances. Cellular phones and pay-TV equipment are examples of markets where the majority of products now available already include smart card readers.
