2. Contents Introduction Smart card/chip Smart chip design Types of smart chips Card Construction Circuits and Card Operating Systems Applications and Benefits 3. Introduction Established in 1996 Syscom Corporation and Smart Chip Limited today occupy the leadership position in both their respective sectors. Today the companies have 47 offices in 23 states of India with employee strength of 550 nationwide. Syscom is 100 per cent subsidiary of Smart Chip Ltd. With over a decade of experience in smart cards management systems, Smart Chip has been delivering successful smart card enabled solutions in India since 1995. 4. Smart card A smart card is a plastic card about the size of a credit card with an embedded microchip that can be loaded with data. A smart card is a portable device that contains some non volatile memory and microprocessor. 5. Smart card These are basically used for telephone calling, cash payments and other applications. This card contain some encrypted key that is compared to a secret key contained on the users processor. Smart cards can hold up to 32,000 bytes. Smart card is an elctronic wallet. 6. Fabrication of smart card Smart cards are credit card-sized and made of flexible plastic, usually polyvinyl chloride (PVC). They are embedded with a micro module containing a single silicon integrated circuit chip with memory and microprocessor. The micro module has eight metallic pads on its surface, each designed to international standards. 7. Micro module metallic chip design VCC: power supply RST: reset signal, used to reset the card's communications CLK: provides the card with a clock signal GND: ground (reference voltage) VPP: designated this as a programming voltage I/O: serial input and output (half-duplex). C4, c8: the two remaining contacts are used for usb interfaces and other uses 8. TYPES OF SMART CARD Contactless smart card ( .eg. Highway toll tags) Contact smart card (SIM Card , Driving license , electronic purpose like debit card etc.) 9. Card Construction Mostly all chip cards are built from layers of differing materials, or substrates, that when brought together properly gives the card a specific life and functionality. The typical card today is made from PVC, Polyester or Polycarbonate. The 3 by 5 mm security chip embedded in the card 10. PC card interaction PC send command to card(through the serial line). The card execute the command and send back the reply. The PC cannot directly access the memory of the card so the data in card is protected from unauthorized access. This is what make the card smart.. 11. Application area Telecommunications E-Governance Health & ID Transport Banking 12. Applications Financial Identification Public transit Computer security Schools Healthcare 13. Problems The plastic card in which the chip is embedded is fairly flexible, and the larger the chip, the higher the probability that normal use could damage it. Cards are often carried in wallets or pockets, a harsh environment for a chip. However, for large banking systems, failure-management costs can be more than offset by fraud reduction. Client-side identification and authentication cards are the most secure way for e.g., internet banking applications, but security is never 100% sure. If the account holder's computer hosts malware, the security model may be broken.
