EmvJ - Chip and PIN/EMV Level 2 Kernel for the Java Virtual Machine
Introduction
The newest addition to CreditCall’ portfolio of software EMV Kernels is EmvJ,
designed from the ground up based on 8 years of experience with the EMV
standards.
The ability to easily add new features across multiple hardware platforms and
operating systems, without impacting existing functionality, is a key reason why
many developers have chosen to implement Java based solutions. This is just one
of the benefits that CreditCall can provide with EmvJ, their EMV Level 2 Kernel
for the Java Virtual Machine.
The Java interface provided by EmvJ, which is based on the software architecture
of the highly successful EmvX Kernel and offers a simple and rapid method of
adding EMV Level 2 functionality any Java based application but using a solution
based upon a virtual machine means the Kernel can be used on other Java
platforms without the need to recertify with EMVCo.
Designed with speed and efficiency in mind, EmvJ can run on the smallest Java
environments with modest system resource utilization.
To ensure that EmvJ can be used in a wide variety of terminal configurations it
has been created as a toolkit of EMV functions that can be called in the correct
order to enable an EMV Level 2 transaction to take place. All the external
functions such as the online authorisation and PIN Pad interfaces are provided
in the form of drivers. A number of these drivers are already available but in
the event that a suitable one is not available, driver templates can be
provided.
Key highlights of the EmvJ Toolkit:
- Ease of adding EMV Level 2 compliance to existing applications - A simple
example performing an EMV compliant transaction with a PIN Pad requires only a
few lines of code.
- The EmvJ Toolkit runs on any platform that supports a Java Virtual Machine.
- Easy interface to peripherals. Drivers for popular card readers and PIN Pads are
already provided with the Toolkit.
- Easy interface to third party EFT packages. Template applications are included
in the EmvJ Toolkit.
- Does not need to be re-certified for each target platform – existing EMVCo
certifications for popular configurations can be re-used, giving increased time
and cost savings.
