your solution is correct. Passing in the $kiosk object makes it accessible to the message handler routine

print "INSTANTIATING KIOSK ==============================\n";
my $kiosk = Kiosk->new($placard, $server, $debug_level);
# start the server on port __
print "INSTANTIATING SERVER port $kiosk_port =========================
+=====\n";
my $server = MyWebServer->new($kiosk_port);
$server->run();
$server->{kiosk} = $kiosk;

this part in HTTP::Server::Simple::CGI; sees it just fine and responds properly ... so THANK YOU. 

    sub handle_request {
        my $self = shift;
        my $cgi  = shift;
        my $json_string = $cgi->param('POSTDATA');
        # { "type":"cardCheck", "date":"1482307795601", "lang": "EN", 
+"machineName":"PLUSMAKM", "cardNumber":"1234567890", "PIN": "1234" }
        print "json_string=$json_string\n";
        $json_dict = decode_json $json_string;
        print "json_dict=" . Dumper($json_dict) . "\n";
        my $response = $self->{kiosk}->process($json_dict);
        print "response=$response\n";
        return $response;
    }

there was one issue in fully implementing your solution (the code worked without it). When you add the "new" method to HTTP::Server::Simple::CGI;object as follows you get an execution error

   sub new {
        my $self = {};
        $self->{class} = $class;
        $self->{kiosk} = undef;
        bless($self,$class);
        return $self;
    }

Can't locate object method "run" via package "main" at http_server.pl line 56, <CONF> line 35. line 56 is

$server->run();

this was the original reason I requested help. Now that I see the code a bit more I guess the question is "how do you exend the HTTP::Server::Simple::CGI; object, but that is another topic. SO I thank you for an excelent easy solution and, if you have any ideas about the ast question, I would love to hear it so I can gain more knowledge about OO in Perl.
