Java Card (JC) refers to a technology that allows small Java-based applications (applets) to be run securely on smart cards and similar small memory footprint devices. Java Card is the tiniest of Java targeted for embedded devices. Java Card gives the user ability to program the device and make them application specific. It is widely used in SIM cards (used in GSM mobile phones) and ATM cards. The first Java Card was introduced in 1997 by several companies including former Schlumberger Limited's card division (then Axalto) and Gemplus (both merged in Gemalto). Java Card products are based on the Java Card Platform specifications developed by Sun Microsystems. Many Java card products also rely on the GlobalPlatform specifications for the secure download of applets on the card.
