Why Java cards are ideal for multi-application markets

Java cards are an innovative approach to smart cards for businesses who need a flexible but secure system. Ensuring a seamless system for your company to work from, you can make sure every process is executed efficiently. Smart cards can help you to grant access to specific areas or equip your employees with a cashless payment option. Likewise, smart cards can act as an ID card or membership card for your on-site facilities.

Opting for a Java card opens up a new world of possibilities when it comes to your operating system. Thanks to numerous features and advanced technology, Java cards offer a secure way of carrying out its defined jobs. Known for being the ideal choice for a multi-application environment, what is it about Java cards that help them stand out from the rest of the market?

Java card operating system

Java cards focus on the notion of being interoperable; the Universal JCard is powered by Oracle’s own developed version of Java 3.0.1, alongside Global Platform 2.2.1 to ensure full compliance with all standard Java card designs. With this in mind, Java card technology allows various designs to work on one platform; making it more convenient for businesses and individuals alike.

Described as an open operating system, it’s built to accommodate multi-applications so that a business can assign different functions to it at any one time. Before multi-application smart cards emerged, each application had to be written for a card-specific operating system which was exclusive to a particular hardware supplier. The card issuer had to commit to one application developer and operating system, with no room for flexibility. If more than one application was required, you would have to carry around separate cards.

So, it’s safe to say that Java cards have transformed the market and provided a modern, convenient way to implement smart cards.

How does a Java card accommodate multi-applications?

Java card technology has been created so that the cards have a large user memory in order to support multiple applications, so only one platform is needed across the company for a smart card system.

But how is it possible? With a Java card operating system, you have the ability to create custom applets, so that the card can accommodate your exact requirements. So, depending on what jobs you need your smart card system to fulfill, you can customize your cards and create a tailored solution for your business. What’s more, you can remove or add custom applets throughout the lifetime of the card; a smart card that uses a Java operating system can change features as many times as you need.

Java applets work via the use of firewalls so that each application runs in isolation from others loaded onto the card. In other words, the operation of one application can’t interfere with the operation of others. So, if you have an application that requires high security, it’s not at risk from an app that doesn’t necessarily require a secure environment.

The perfect solution for a number of different sectors, Java cards may well be the future of the smart card industry.
