➢Hybrid Cards
6. 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.
7. 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.
8. Hybrids
• Implements former two
interfaces on a single
card.
•
•
On developing stage.
Example is Andante,
Porto’s multi-application
transport card.
