=head1 NAME
Business::CN::IdentityCard - Validate the Identity Card NO. in China
=head1 SYNOPSIS
use Business::CN::IdentityCard;
my $id = '11010519491231002X'; # a unsure identity card no.
my $idv = new Business::CN::IdentityCard;
if ($idv->validate($id)) { # call the validate_id method
print 'Pass';
print $idv->gender; # the gender of the id, default is *Chinese*
print $idv->gender('EN'); # the English gender: Male|Female
print $idv->birthday; # the birthday of the id, eg: 1975-10-31
print $idv->province; # the province of the id, in Chinese
print $idv->district; # the district of the id, *NOT* suggested
} else {
print $idv->err; # the type of error, details see below
print $idv->errstr; # the error detail
}
=head1 DESCRIPTION
It validates the given Identity Card NO., and give some info(including gender, birthday, province and district) of the id.
There is a Chinese document @ L<http://www.fayland.org/IDCard/Validate.html>. It explain the algorithm of how-to validate the Identity Card no.
=head1 METHOD
=over 4
=item new
you can declare the object with the id, such as
my $idv = new Business::CN::IdentityCard($id);
$idv->validate;
=item validate
if the id is provided by new, u can ignore the parameter, otherwise the parameter is needed. if the ID is correct, return 1, otherwise return 0 and u can get the error details. see below.
=item gender
return the gender of the id owner. default return the Chinese gender, use gender('EN') to get the Female or Male.
=item birthday
return the birthday of the id owner. the format is like YYYY-MM-DD
=item province
return the province of the id owner. It's Chinese.
=item district
B<NOT> suggested. because it's not perfect and takes memory. of course, use it if needed.
=item err
return the type of the error.
=over 4
=item B<LENGTH>
if the length of the id is not 15 or 18.
=item B<BIRTHDAY>
if the birthday is not a normal date.
=item B<PROVINCE>
no such province code. :)
=item B<DISTRICT>
what district? I haven't heard that before.
=item B<POSTFIX>
the last digit is definitely faked.
=back
=item errstr
the detail of the error
=back
