 This extension was originally written in 2005 by Johann Dantant. In 2011 Johannes Findeisen took his code and updated it to work with the current PHP version. Johannes maintains the code to this day, but there have been some contributions from other people in the past. All people who have worked on extending or porting the "pcsc" extension are listed below in alphabetical order by their last name. Thanks to all!
