Monetra 6.0

Monetra (formerly known as MCVE) is a scalable credit card processing engine for Linux and UNIX. The project is designed to handle credit card authorizations and is certified to support major clearing house protocols.
Features include support for multiple modems, multiple merchant accounts, and multiple processors, all simultaneously -- as well as IP and SSL connectivity along side SQL database support.
Designed in C, conforming to POSIX standards, and utilizing light weight processes (threads), this product is able to handle a large number of transactions with high speed and minimal CPU usage.
Enhancements:
- A secure recurring billing module and card storage subsystem returning unique tracking tokens has been added and branded as Monetra DSS.
- This assists integrators with their PCI compliance so they dont need to store card numbers outside of Monetra.
- There is DNS caching for improved latency.
- Givex and FifthThrid 610 support have been added.
- Global Payments, VITAL, and NPC re-certifications.
- Visa gift-card support (balance inquiry and partial auths), as well as new card systems compliance updates for October 2007.
- Mac OS X for Intel, Windows Vista, and OpenBSD 4.0 support has also been added.
