Typical architecture

Java Card Wallet → Java Card Applet → JCRE/JCVM → Secure Microcontroller → NFC/Contact Interface → Payment Terminal

For a commercial payment card, the Java Card platform alone is not sufficient. The payment application needs to meet the applicable EMV/payment-network, security, personalization and certification requirements.

Java Card Payment Wallet

A Java Card Payment Wallet is a secure smart card-based payment platform designed to host payment applications, cryptographic credentials and digital wallet functionality inside a secure Java Card environment. Java Card technology enables applications to run securely on tamper-resistant smart card microcontrollers and secure elements.

A Java Card Payment Wallet can be designed for contactless payment, NFC payment, smart card payment, payment credentials, digital wallets and secure transaction applications. Depending on the hardware platform and application requirements, Java Card technology can provide a flexible environment for developing and deploying secure payment applications.

What Is a Java Card Payment Wallet?

A Java Card Payment Wallet uses a Java Card secure element to securely manage payment-related applications and credentials. Instead of keeping sensitive payment information in ordinary memory, security-sensitive operations can be performed within the secure microcontroller.

The Java Card platform provides a Java Card Virtual Machine (JCVM) and Java Card Runtime Environment (JCRE) that allow Java Card applets to execute within the secure card environment.

A typical Java Card Payment Wallet may contain:

• Payment application
• Digital payment credentials
• Cryptographic keys
• Authentication functions
• Secure PIN management
• Transaction counters
• NFC/contactless payment functionality
• Loyalty or membership applications
• Multiple secure card applications

Java Card Payment Wallet Architecture

A typical Java Card payment architecture consists of several security layers:

Java Card Wallet Payment Application → Java Card Applet → JCRE/JCVM → Secure Microcontroller → Contactless/NFC Interface → Payment Terminal

The Java Card applet contains the application logic, while the secure microcontroller provides protected execution and storage.

For contactless implementations, the underlying card hardware must provide the appropriate ISO/IEC 14443/NFC interface and associated security functionality.

Java Card Payment Applet

The Java Card Payment Applet is the software component that implements payment-related functionality on the Java Card platform.

Java Card applets can be installed, personalized and managed using GlobalPlatform technologies. Depending on the implementation, an applet can provide functions such as:

• Secure credential management
• Cardholder verification
• Cryptographic operations
• Transaction processing
• Secure data storage
• Authentication
• Application lifecycle management
• Contactless transaction processing

The exact payment functionality depends on the Java Card platform, applet design and applicable payment specifications.

Java Card NFC Payment

A Java Card NFC Payment solution combines a Java Card secure element with a suitable contactless interface to enable secure communication with NFC-compatible payment infrastructure.

Contactless Java Card platforms can be used for applications involving:

• NFC payment
• Contactless smart cards
• Transit payment
• Access control
• Loyalty applications
• Identification
• Secure authentication
• Digital credentials

The actual payment implementation must use hardware and software that meet the requirements of the intended payment ecosystem.

Java Card Contactless Payment

Java Card Contactless Payment applications require a secure microcontroller, contactless interface and payment application capable of communicating with the target payment infrastructure.

A contactless Java Card can contain one or more secure applications while maintaining isolation between applications through the Java Card security model.

For commercial payment deployments, additional requirements may include payment-network specifications, security certification, EMV-related requirements, personalization systems and other industry certifications.

Java Card and EMV Payment

Java Card technology is frequently associated with secure payment smart cards because it provides a programmable secure environment for smart card applications.

A Java Card EMV Payment implementation may use a Java Card platform as the secure execution environment for an EMV payment application. However, simply using a Java Card chip does not automatically make a card EMV-certified.

Commercial payment products require the appropriate:

• EMV specifications
• Payment application
• Security architecture
• Cryptographic implementation
• Certification
• Personalization process
• Payment-network requirements

Therefore, the Java Card platform should be selected according to the complete payment application and certification requirements.
