ISO-8583 SDK for Java and Microsoft.NET


ISO8583 formatter/parser or call it Simple API for ISO-8583, is advanced ISO 8583 tool/SDK for financial transaction applications such as message routers, switches, authorization servers, ATMs, POS devices and ISO8583 based clearing or settlement files etc.
Our SDK library implements parsing and formatting of all 128 fields and since version 3 it supports also the extended third bitmap option in field 65 and therefore fields 129..192. SDK supports versions of 1987 (0xxx messages) and 1993 (1xxx messages) and since version 2.5 also version 2003 (2xxx messages) are supported. From version 3 update 1 any version is virtually supported so MTI could start with any number 0..9.   In addition our SDK is flexible and field settings can be customized at runtime as any of the 128/192 fields can have Your customized type and/or length, that is very useful because there is unlimited dialects and modified versions of this standard in use worldwide.

The important object in package is Message object that can contain any number of fields defined by ISO8583.     The messages itself are built up from smaller pieces that are ISOField and Bitmap objects. For creating and formatting of a message you just need to create a new message object and add necessary field information, the complete formatting is done by SDK library.
To parse incoming messages it is only necessary to set the input stream or byte array as a parameter and the parser will return the message object that contains all the fields available. Field information can be handled in applicable binary, alphanumeric or number form or can be converted to strings.

ISO-8583 SDK

Our ISO8583 SDK/API is great help for OO environments and makes simple to add ISO8583 capabilities for applications, without no need to spend significant amount of time and money for implementing low level parsing and formatting routines.

Note: Our ISO-8583 SDK V2 and V3 are available for Java (as jar package) and for .NET C# or Visual Basic (as dll)!

System requirements:
Java: The ISO-8583 SDK is compatible with Java (pre 3.5 only 1.3, 1.4), 1.5, 1.6, 1.7 or later. The in-memory performance on 3.4GHz AMD A10 (single thread single core used, os Win 7 64 bit) and jdk 1.7x32 achieved is about 27000 and on jdk 1.8x64 about 40000  formatting+parsing cycles per second of an average message (with 16 fields incl. 2 bitmaps). 

.NET:  ISO-8583 SDK C# .NET version requires .net framework 2 or later and performance is now also about 31000 formatting+parsing cycles per second on AMD A10 3.4GHz (single thread one core used os Win 7 64 bit. )

What users have said about our ISO-8583 SDK:

In general we are very happy with the SDK- it does it's job pretty good and the possibility of reconfiguring the field definitions makes it really flexible.
The only thing that would improve the usage experience that I can instantly suggest is that the bitmaps should be updated automatically if you add/remove a field.

But it's no problem to write a live template in your favourite IDE to do this job.

Thanks for this, we are happy with the sdk - does exactly what we need,
the next step for us would be to get the developer license.
