Introduction
 The first Java Card was introduced in 1996 by Schlumberge’s
card division which later merged with Gemplus to form
Gemalto
 Java Card refers to a technology that allows Java-based
applications to be run securely on smart cards.
 Java Card gives the user, the ability to program the device and
make them application specific.
 Java Card is a smart card that is capable of running programs
written in Java.

Smart Cards
 A smart card is a plastic
card that contains an
embedded integrated
circuit (IC)
 Examples:
 Our very Own T-Card!
 Credit Cards
 Cell Phone SIM Cards

Java Cards are Smart! How??
 They store and process Information
 Smart Cards can be used to add
authentication and secure access to
information systems that require a high
level of security

JAVA CARD
What is a Java Card?
Simple Answer:
Java+Card=Java card
Adoption of Java platform for usage on Smart cards .
 A programmable smart card
 A multi-application smart card
 A smart card for secure application loading

Java Card Architecture & Components

EVELOPING A JAVA CARD APPLET
1.Write the Java source
2.Compile your source
3.Convert the class files into a
Converted Applet (CAP)
file(Binary representation of
Classes & interfaces)
4.Verify that the CAP is valid
5.Install the CAP file

Limitations

CONCLUSION
•Java Card and other flavors of Java will open new markets
•Java Card Technology defines a run time environment that
supports the smart card memory, communication, security and
application execution model.
•Java Card Technology fits java system software in a smart
card while conserving enough space for applications.
•Java Card mitigates some risks associated with Java such as
dynamic class loading
