'''Java Card''' is a software technology that allows [[Java platform|Java]]-based applications ([[applet]]s) to be run securely on [[smart card]]s and more generally on similar secure small memory footprint devices<ref name="Chen 2000">{{cite book | last=Chen | first=Z. | title=Java Card Technology for Smart Cards: Architecture and Programmer's Guide | publisher=Addison-Wesley | series=Addison-Wesley Java Series | year=2000 | isbn=978-0-201-70329-0 | url=https://archive.org/details/javacardtmtechno00zhiq | url-access=registration | access-date=9 April 2019 }}</ref>which are called “secure elements” (SE). Today, a Secure Element is not limited to its smart cards and other removable cryptographic tokens form factors; embedded SEs soldered onto a device board and new security designs embedded into general purpose chips are also widely used. Java Card addresses this hardware fragmentation and specificities while retaining code portability brought forward by Java.

Java Card is the tiniest of Java platforms targeted for embedded devices. Java Card gives the user the ability to program the devices and make them application specific. It is widely used in different markets: wireless telecommunications within SIM cards and embedded SIM, payment within banking cards<ref>{{Citation|last=Oracle Learning Library|title=Developing Java Card Applications|date=2013-01-30|url=https://www.youtube.com/watch?v=khgT5dwKvOo |archive-url=https://ghostarchive.org/varchive/youtube/20211213/khgT5dwKvOo |archive-date=2021-12-13 |url-status=live|access-date=2019-04-18}}{{cbignore}}</ref> and NFC mobile payment and for Identityidentity cards, healthcare cards, and passports. Several IoT products like gateways are also using Java Card based products to secure communications with a cloud service for instance.

The first Java Card was introduced in 1996 by [[Schlumberger Limited|Schlumberger]]'s card division which later merged with [[Gemplus]] to form [[Gemalto]]. Java Card products are based on the specifications by [[Sun Microsystems]] (later a [[subsidiary]] of [[Oracle Corporation]]). Many Java card products also rely on the GlobalPlatform specifications for the secure management of applications on the card (download, installation, personalization, deletion).
