  3. 3. INTRODUCTION A Smart Card is like an “electronic wallet”. It provides not only memory capacity, but computational capability as well and thus the chip is capable of processing data. Smart Cards can store several hundred times more data than a conventional cards with a magnetic stripe and can be programmed to reveal only the relevant information.
  4. 4. What is a Smart Cards ? A smart card is a device that includes an embedded integrated circuit that can be either a secure microcontroller or equivalent intelligence with internal memory or a memory chip alone. Two types -Memory-only chips -Microprocessor chips
  5. 5. What is a Smart Cards ? Can hold up to 32,000 bytes. With an embedded microcontroller, smart cards have the unique ability to store large amounts of data, carry out their own on-card functions (e.g., encryption and mutual authentication) and interact intelligently with a smart card reader.
  6. 6. History The technology has its historical origin in the seventies when inventors in Germany , Japan , and France filed the original patents. While inventors in the U.S , Japan and Austria, were issued patents, it was French who put big money to push the techhnology.
  7. 7. History The industry has been growing at tremendous rate is shipping more than one billion (1,000,000,000) cards per year (since 1998). The current world population of Smart Cards of some 1.7 billion is set to increase to 4 billion or more cards within the next 3-4 years.

  9. 9. MicroAnatomy of a Smart Card
  10. 10. Smart Card Pieces and parts Processor Math Co-processor (optional) Memory ROM EEPROM RAM
  11. 11. Varieties of Smart CardsSmart Cards come in two varieties: Contact Smart Card . Contactless Smart Card.
  12. 12. Contact Smart Card The contact Smart Card has a set of gold-plated electrical contacts embedded in the surface of the plastic on one side. This card has a contact plate on the face ,which is a small gold chip about ½ in diameter on the back like a “credit card”
  13. 13. Contactless Smart Card A contactless Smart Card looks just like a plastic “credit card” with a computer chip and an antenna coil embedded within the card. The antenna is typically 3-5 turns of very thin wire ,connected to the contactless chip. Component Antenna Plastic Contacts
  14. 14.  Such contactless Smart Cards are used when transactions must be processed quickly, as in mass-transit toll collection or wherever the cardholder is in motion at the moment of the transaction.
  15. 15. Major Benefits that Smart Cards offerSecurity : a) chip is tamper-resistant b) information stored on the card can be PIN coded c) capable of performing encryption and/or read/write d) each smart card has its own unique serial numberIntelligence : a) capable of processing , not just storing information
  16. 16. Major Benefits that Smart Cards offer b) Smart cards can communicate with devices through smart card readerConvenience : a) chip is tamper-resistant b) Smart Cards provide a portable, easy to use form factor that many are familiar with using
  17. 17. Smart Card Services Data Storage & retrieval. Authentication. Cryptography. Signature . Multiple application.
  18. 18. Smart Card Applications Smart Cards are being deployed in public and private marketplaces. There are over 300,000,000 GSM mobile telephones with Smart Cards which contain the mobile phone security and subscription information. Streamlining healthcare Services. Automating transportation Services.
  19. 19. Future Embedding similar circuits in everyday objects, such as key rings, watches, glasses, rings or earrings could perform the same electronic function. Soon it will be possible to authorize the use of electronic information in Smart Cards by using a spoken word or the touch of a hand. In the future, the traditional magnetic strip card will be replaced and integrated together into a single card by using the multi-application Smart Card, which is known as an electronic purse or wallet in the Smart Card industry.
  20. 20.  With global financial institutions pushing for migrating their credit card and debit card transactions towards smart card-based transactions, the future of smart cards does seem bright. "From year 2005 onwards, as per EMV II compliance (EuroPay, MasterCard, Visa), all new credit/debit cards will be issued only on chip (instead of magnetic strip) which will drive huge growth in this segment. Security concerns in financial transactions will also force banks to opt for smart cards sooner or later."
  21. 21.  Also, the emergence of contactless smart cards could be a key driver for smart card usage—the next time you drive through the toll gate of a bridge, a smart card reader at the toll bridge could just debit the toll from the smart card fixed on your car as you drive past the bridge.
  22. 22. Thank You
  23. 23. This is just the beginning; soon it will influence the way we shop, see thedoctor, use the telephone and even enjoy leisure!!! Any Query?????
