Categories of Smart Cards Memory Cards

Containing a memory chip (several K bits) with hardwired logic,

mostly used as prepaid cards, low cost.

Microprocessor Cards (our focus for this topic) like small portable computers (without keyboard or

monitor screen), increased security capabilities, can integrate several applications.


Categories of Smart Cards (cont.)

Contact Cards must be inserted into a card reader or terminal (Card

Acceptance Device), more commonly used

Contact-less Cards Can function when placed close enough to the

terminal, Ideal for fast transactions, not easily worn out, can be of different physical sizes, transmitted data can be intercepted

About Smart Card Software Smart card system

Host (Terminal )system + Card system

Smart card operating systems are typically file system-centric (based on ISO 7816-4)

Most conventional card applications involve just file manipulations (select, deselect, read, write)

Software development involves (1) operating system providers, (2) card terminal vendors, (3) application developers, and (4) card issuers


Chip Card File System Most smart card operating systems are typically File System-Centric

based on ISO 7816-4MF

Realizing the Multiple-Application Vision


Benefits of Open OS Interoperability Secure loading of applets into card, even

after issuance An existing field application can be ported

onto a multi-application card, without changing the terminal software

Firewalls between applets confidentiality of data

Applet develop in high level language (java, C, …) very quick time to market
