What is Java Card Applet Development?

Java Card applet development is the process of designing, programming, testing, and deploying secure applications on Java Card-enabled smart cards and secure elements. These applets operate within a highly secure chip environment and are commonly used for:

• Secure authentication
• Banking and payment applications
• PKI and digital signature solutions
• FIDO authentication
• SIM and telecom applications
• NFC access control systems
• Government ID cards
• Healthcare smart cards
• Secure storage applications
• Loyalty and transit systems
• Hardware security tokens

Java Card technology enables multiple secure applications to run independently on a single smart card while maintaining high security standards.
