Java Card technology allows Java-based applications to run securely on smart cards. A Java Card is a programmable smart card that supports running multiple applications using the Java programming language. Java Card applications are compiled to CAP files that are verified and installed on the card. Java Card provides features like inheritance and object orientation while limiting capabilities like dynamic class loading for security. Java Cards are used in various applications including banking, transportation and mobile phones.

3. 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.

4. 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

5. 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

6. 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

7. Java Card Architecture & Components

8. 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

9. Features of Java Card

13. 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
