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.

JavaCard development QuickstartMartin Paljak

Smart cards, also known as JavaCards, are tiny computers without interfaces that contain a CPU, memory, and cryptographic capabilities. The JavaCard platform allows developing applications using Java that can be loaded securely onto smart cards for uses like payment and identity. To get started, developers need a JavaCard-compatible smart card, card reader, JavaCard SDK, tools to convert code to a loadable format and install it onto cards, and knowledge of protocols like APDU and GlobalPlatform for applet management. Community resources exist online for learning and engaging with others developing for the JavaCard platform.

Javacard Samiksha90

Java Card allows Java-based applications called applets to run securely on smart cards and small memory devices. It combines Java technology with smart cards, providing developers the ability to program smart cards and make them application-specific. Java Card applets consist of a back-end application, host application, interface device like a card reader, the on-card applet, and supporting software. The applet is developed in Java source code, compiled, converted to a CAP file and installed on the card, where it runs in a Java Card Runtime Environment with limited memory and computing power compared to regular Java. Java Card is used in various applications including financial, mobile communication, and more.

jCardSim - development platform for Java Card ApplicationsMikhail Dudarev

jCardSim is a Java Card development platform that allows developers to test and prototype Java Card applications without using actual smart cards. It provides a full emulation of the Java Card environment and supports common cryptographic algorithms. Some key advantages are its cross-platform support, ability to rapidly prototype and test applications, and ease of debugging interactions between apps and the Java Card runtime environment. It is used by companies like Thales and BMW/Audi for JavaCard app development as well as other organizations for prototyping and education.

JavacardtechVivek Bajpai

Java Card technology allows Java programming on smart cards by implementing a subset of the Java programming language. A Java Card application consists of an on-card applet and supporting off-card systems. Communication with the applet occurs through Application Protocol Data Units (APDUs) or Java Card Remote Method Invocation (RMI). The Java Card runtime environment provides APIs for smart card functions like secure element access while imposing limitations due to hardware constraints such as no threads or doubles.

Study of Java Card and its Applicationeditor1knowledgecuddle

Sun Microsystems defined a set of specifications for a subset of Java technology to create applications for them, Java Card applets. A device that supports these specifications is referred to as a Java Card platform. On a Java Card platform, multiple applications from different vendors can coexist securely. The Java Card platform is the tiniest of Java targeted for embedded devices. It is an open, interoperable platform for smart cards and secure tokens. The technology is widely used in SIM cards (it's used in GSM mobile phones) and ATM cards. Java Card gives users the ability to program a device and make it application specific and lets smart card developers use a common card platform. Smart cards, unlike magnetic stripe cards, can carry all necessary functions and information on the card; therefore, they do not require access to remote databases at the time of the transaction.

YSPH VMOC Special Report - Measles Outbreak Southwest US 4-30-2025.pptxYale School of Public Health - The Virtual Medical Operations Center (VMOC)

A measles outbreak originating in West Texas has been linked to confirmed cases in New Mexico, with additional cases reported in Oklahoma and Kansas. The current case count is 795 from Texas, New Mexico, Oklahoma, and Kansas. 95 individuals have required hospitalization, and 3 deaths, 2 children in Texas and one adult in New Mexico. These fatalities mark the first measles-related deaths in the United States since 2015 and the first pediatric measles death since 2003. The YSPH Virtual Medical Operations Center Briefs (VMOC) were created as a service-learning project by faculty and graduate students at the Yale School of Public Health in response to the 2010 Haiti Earthquake. Each year, the VMOC Briefs are produced by students enrolled in Environmental Health Science Course 581 - Public Health Emergencies: Disaster Planning and Response. These briefs compile diverse information sources – including status reports, maps, news articles, and web content– into a single, easily digestible document that can be widely shared and used interactively. Key features of this report include: - Comprehensive Overview: Provides situation updates, maps, relevant news, and web resources. - Accessibility: Designed for easy reading, wide distribution, and interactive use. - Collaboration: The “unlocked" format enables other responders to share, copy, and adapt seamlessly. The students learn by doing, quickly discovering how and where to find critical information and presenting it in an easily understood manner.
