- CCVS
CCVS, or Credit Card Verification System, was a credit card processing system designed for
Posix -based operating systems, includingUnix ,Linux , and a version forPalmOS shown at trade shows. It was originally sold by Hell's Kitchen Systems, Inc. from 1997 onward and was acquired along with the company byRed Hat in January 2000. In 2002, Red Hat decided to exit theeCommerce market as an ISV, discontinued support for CCVS, and recommended that customers transition toMCVE .The CCVS API supported use under
PHP , Java,Perl ,Tcl , and C to allow merchants to communicate directly with the credit card clearing house instead of using Internet-based intermediaries. Along with Red Hat's decision to discontinue support for this extension, it has also been removed fromPHP and is no longer available since version 4.3.0. An alternative to CCVS isMCVE .External links
