Design
A smart card may have the following generic characteristics:
- Dimensions similar to those of a credit card. ID-1 of the ISO/IEC 7810 standard defines cards as nominally 85.60 by 53.98 millimetres (3.370 in × 2.125 in). Another popular size is ID-000 which is nominally 25 by 15 millimetres (0.984 in × 0.591 in) (commonly used in SIM cards). Both are 0.76 millimetres (0.030 in) thick.
- Contains a tamper-resistant security system (for example a secure cryptoprocessor and a secure file system) and provides security services (e.g., protects in-memory information).
- Managed by an administration system which securely interchanges information and configuration settings with the card, controlling card blacklisting and application-data updates.
- Communicates with external services via card-reading devices, such as ticket readers, ATMs, etc.

Famous quotes containing the word design:
“I begin with a design for a hearse.
For Christs sake not black
nor white eitherand not polished!
Let it be weatheredlike a farm wagon”
—William Carlos Williams (18831963)
“The reason American cars dont sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. Thats why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
“Westerners inherit
A design for living
Deeper into matter
Not without due patter
Of a great misgiving.”
—Robert Frost (18741963)
