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.
