Smart Card Application Development Using Java

An efficient installation for applets to be post-issuance of Java Card system using an IC chip

“…Java Card has recently been recognized as a dominating platform for smart cards and SIM/USIM cards using an Integrated Circuit (IC) chip [1,2,3,5,6,8]. The Java Card system is issued with previously made applets and is also able to download a new applet whenever users or vendors need after it is issued.…”

“…The Java Card system is issued with previously made applets and is also able to download a new applet whenever users or vendors need after it is issued. These methods are called pre-issuance and post-issuance [1,2,3]. In order to download a new applet is different from a standard Java platform because the Java Card platform runs a tiny Java Card Runtime Environment (JCRE) optimized for an embedded device with limited memory and computing power in the IC chip.…”

High performance annotation-aware JVM for Java cards

“…Java Card is based on a subset of the Java API plus some special-purpose card commands [4,5]. The Java Card technology enables portability of applications, and provides a secure platform to store and execute multiple applications, called applets, 1 on a smart card [6]. Applets are small enough so that several of them can fit into a single card with small amount of memory.…”
