jPOS is a free and open source library/framework that can be used to implement financial interchanges based on the ISO 8583 standard and other Point of Sale related peripherals and protocols.

It currently supports versions 1987, 1993 and 2003 of the standard as well as multiple ANSX9.24 standards.

The project page is: http://jpos.org
