Applications and Benefits
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.
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.
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 user’s
Smart cards can hold up to 32,000 bytes.
Smart card is an elctronic wallet.
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
The micro module has eight metallic pads on its surface,
each designed to international standards.

VCC: power supply
RST: reset signal, used to reset the card's
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
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

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…..
Health & ID
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
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.
