jPOS is an open-source, mission-critical enterprise software, based on International Organization for Standardization transaction card originated messages standard (ISO-8583). Java platform-based jPOS provides an open-source software bridge between ISO 8583-based messages and your internal processing networks and systems. It serves as the messaging foundation for systems that exchange electronic transactions made by cardholders using payment cards.

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
