Java Card Architecture
Java Card enables applications to operate within secure hardware environments such as smart cards and secure elements. Ciright applications may use these established technologies where applicable—without claiming ownership of Java Card itself.
Detail
How it fits Keyra
- From one static card to a secure platformThe architecture changes from one static card to one secure hardware platform supporting multiple applications and credentials—applets, secure execution, key storage, application isolation, provisioning, lifecycle management, cryptographic operations, and interoperability.
- Why it mattered strategicallyEnterprises need isolation between applications, controlled updates, and cryptographic operations inside hardware. Java Card-class environments make multi-application secure cards practical.
- What Keyra inheritsApplet-oriented thinking, credential isolation, and lifecycle discipline remain part of Keyra’s secure-card lineage.
