A Study of Java Card and its Application: Study of Java Card and its Application

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