3. INTRODUCTION
 Java Card refers to a technology that allows java-based
applications(applets)to be run securely on smart cards and similar
small memory footprint devices.
 Java Card gives the user ability to program the device and make them
application specific.
 The Java Card is an extremely secure Java-powered electronic token.
 Java Card could have a number of real-world applications.

HISTORY OF JAVA CARD

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

6. 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

7. ARCHITECTURE

8. 8
Elements of Java Card Application:
A complete Java Card application consists of :
a back-end application
a host (off-card) application
an interface device (card reader )
the on-card applet
user credentials
and supporting software

9. WORKING

10. 10
The Back-End Application and Systems
Provide connectivity to security systems
Example:
In an electronic payment system, the back-end
application could provide access to credit card
and other payment information

11. 11
The Reader-Side
Consists of two parts:
Host Application
Card Acceptance Device
Think of a bank machine:
Host Application as the Computer that provides
interaction with the system
Card Acceptance Device being where you put your debit
card in

12. 12
The Card-Side
Elements:
One or more Java Applets
Card’s operating System
Java Card Runtime
Environment(JCRE)
◦ Java Card Virtual Machine
◦ Java Card Framework and APIs

13. DEVELOPING 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

14. APPLICATION AREAS
Financial
• Smart Credit / Debit
• E-Purses
• Loyalty Programs
Mobile Communication
• Infotainment
• Business Support
• Network Optimizers

15. Advantages
•Interoperable
•Secure
•Multi-Application capable
•Dynamic
•Compatible with existing standards
•Hardware Independence

16. CHALLENGES
Java cards have very restricted resources
1.Limited Memory
2.Limited Computing Power
Java Card doesn’t support some of java features
1.Large primitive data types : long, double, float
2.char,string
3.Multidimensional array
4.Dynamic class loading
5.Garbage collection
6.Multithreading
7.Object Cloning

17. 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
