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. Key features of Java Card include support for small data types and one-dimensional arrays, as well as object-oriented features, while not supporting large data types, characters, strings, or dynamic class loading. Java Card provides advantages like interoperability, security, and compatibility with existing standards.

- 2. Presentation Agenda Introduction What is Smart Card? Java Card Java Card Architecture Developing a Java Card Application Features Applications Advantages Limitations Conclusion
- 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

- 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 SUPPORTED NOT SUPPORTED • Small primitive data types: • Large primitive data types: boolean, byte, short. long, double, float. • Characters, strings. • One dimensional arrays. • Multidimensional arrays. • Object oriented features: • Dynamic class loading. inheritance, virtual • Garbage collection. methods, dynamic object • Threads. creation, overloading, • Object Cloning scope.
- 10. Applications Cellular phone GSM cards Public phone cards (pre- paid) Banking cards Health cards Game cards Transport cards
- 11. Advantages •Interoperable •Secure •Multi-Application capable •Dynamic •Compatible with existing standards •Hardware Independence
- 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
