Java Card IDE 5.3

Java Card IDE is an integrated development environment designed to streamline the creation of Java Card applets for smart cards and secure elements. It brings the full development cycle into one place—from writing code and managing AIDs to building CAP files, installing applets, and testing APDU exchanges—so you can prototype and iterate quickly with minimal setup.

Key capabilities:

• Project templates and a code editor tailored to the Java Card API
• Automated build pipeline to compile classes and generate CAP/export files
• Package and applet AID management with validation
• APDU console and scripting for sending, recording, and debugging commands
• Support for simulators and connected card readers (PC/SC) for on‑device testing
• Integration with common GlobalPlatform tooling for load, install, and delete
• Sample projects, inline documentation, and customizable build tasks
• Cross‑platform operation to fit diverse development environments

Whether you are learning Java Card or delivering production applets, Java Card IDE helps reduce tooling complexity and shortens the path from source code to a tested, deployable CAP.
