What is Smart Card?What is Smart Card?
Small plastic card embedded with an IC chip.
Chip can be either a memory or microprocessor type.
Useful for storing and transacting data.
Data is associated with either value, information, or both.
History of Smart CardsHistory of Smart Cards In 1968 & 1969, German engineers Helmut
Grottrup & Jurgen Dethloff filed patents for automated chip card.
French inventor Roland Moreno patented the memory card concept in 1974.
Michel Ugon from Honeywell Bull invented the first microprocessor smart card in 1977.
Until mid 80s most of the work on Smart Cards was at the research and development level.
First commercial use was French debit cards.

Types of Smart CardsTypes of Smart CardsBased on the way the smart card interacts with the Card Reader, smart cards are of three types:
Contact Smart Cards
Contactless Smart Cards
Hybrid Cards
Contact Smart Card
Defined in ISO 7810 standard.
Have contact area of approx. 1 cm2
This area comprises of several gold-plated contact pads.
Pads provides electrical conductivity.
Power is supplied by card reader.
Contactless smart cards
• Uses RF induction technology to communicate and to be powered.
• Defined in ISO 14443 standard.
• Communicates at data rates of 106-848 kbps.
• Requires an antenna to communicate.
Hybrids
• Implements former two
interfaces on a single
card.
• On developing stage.
• Example is Andante,
Porto’s multi-application
transport card.
ApplicationsApplications
• Financial > As ATM cards, Fuel cards, SIMs. > As electronic wallet.• Identification• Public Transit. • Educational Institutes. > Tracking Student attendance. > As an electronic purse to pay various
bills. > Access control of some buildings.• In healthcare.
