4. Plastic Cards
Visual identity application
Plain plastic card is enough
Magnetic strip (e.g. credit cards)
Visual data also available in machine readable form
No security of data
Electronic memory cards
Machine readable data
Some security (vendor specific)
5. What is a 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, used for telephone
calling, cash payments , and other
applications, and then periodically
refreshed for additional use.
7. History
70’s
Smart Card First Patent in Germany and later in
France and Japan.
80’s
Mass usage in Pay Phones and Debit Cards.
90’s
Smart Card based Mobiles Chips & Sim Cards.
8. History
2000’s
Payment and Ticketing Applications
Credit cards, Mass transit (Smartrip)
Healthcare and Identification
Insurance information, Drivers license
12. Electrical Signals Description
VCC : Power supply input
RST : Either used itself (reset signal supplied from the interface device) or in
combination with an internal reset control circuit (optional use by the card) .
CLK : Clocking or timing signal (optional use by the
card).
GND : Ground (reference voltage). Fig : A smart card pin out
VPP : Programming voltage input (deprecated / optional use by the card).
I/O : Input or Output for serial data to the integrated circuit inside the card.
AUX1(C4): Auxilliary contact; USB devices: D+
AUX2(C8) : Auxilliary contact; USB devices: D-
13. CARD STRUCTURE
Out of the eight contacts only six are used. Vcc is
the supply voltage, Vss is the ground reference
voltage against which the Vcc potential is
measured, Vpp connector is used for the high
voltage signal,chip receives commands &
interchanges data.
14. Typical Configurations
256 bytes to 4KB RAM.
8KB to 32KB ROM.
1KB to 32KB EEPROM.
8-bit to 16-bit CPU. 8051 based designs
are common.
15. Smart Card Readers
Computer based readers
Connect through USB or COM (Serial) ports
Dedicated terminals
Usually with a small screen, keypad, printer,
often also have biometric devices such as thumb
print scanner.
16. Terminal/PC Card Interaction
The terminal/PC sends commands to the card
(through the serial line).
The card executes the command and sends back
the reply.
The terminal/PC cannot directly access memory
of the card so data in the card is protected from
unauthorized access. This is what makes the
card smart.
17. Why Smart Cards?
Security: Data and codes on the card are encrypted by the
chip maker. The Smart Card’s circuit chip almost impossible
to forge.
Trust: Minimal human interaction.
Portability.
Less Paper work: Eco-Friendly
18. Two Types of Chips
Memory chip Microprocessor
Acts as a small floppy Can add, delete, and
disk with optional manipulate its memory.
security Acts as a miniature
Are inexpensive computer that includes an
Offer little security operating system, hard
features disk, and input/output
ports.
Provides more security and
memory and can even
download applications.

20. Smart Cards in
everyday life…
Loyalty
Transport
Ticketing
Payment
Health card
Smart Poster
Communication
21. Contact Smart Cards
Requires insertion into a
smart card reader with a
direct connection
This physical contact
allows for transmission of
commands, data, and card
status to take place
23. Contactless Smart Cards
Require only close proximity to a
reader
Both the reader and card have
antennas through which the two
communicate
Ideal for applications that require
very fast card interfaces
24. ISO 14443.
International standard.
Deals – only contactless smart cards.
Defines:-
a. Interface.
b. Radio frequency interface.
c. Electrical interface.
d. Operating distance.
Etc…..
25. Dual interface smart cards.
Also called Combi card.
Has a single chip over it.
Has both contact as well as contactless
interfaces.
We can use the same chip using either contact or
contactless interface with a high level of security.
29. Categories of Smart Cards
Based on the type of IC chip
embedded on the Smart Card.
They are categorized into
three types :-
IC Micro Processor Cards
IC Memory Cards
Optical Memory Cards
30. Key Attributes
Security
to make the Digital Life safe and enjoyable
Ease of Use
to enable all of us to access to the Digital World
Privacy
to respect each individual’s freedom and intimacy
SAFE
