I just released a new version 1.4.13 of pcsc-perl, the Perl wrapper for PC/SC.
This version just fixes a warning when you use Perl 5.16.
See the article "PCSC sample in Perl" for code sample of PC/SC in Perl.
pcsc-perl is also available at CPAN: pcsc-perl-1.4.13 with the online API documentation for Chipcard::PCSC and Chipcard::PCSC::Card.
