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 @ http://www.fayland.org/IDCard/Validate.html. It explain the algorithm of how-to validate the Identity Card no.

METHOD ^

you can declare the object with the id, such as

 my $idv = new Business::CN::IdentityCard($id);
 $idv->validate;
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.

gender

return the gender of the id owner. default return the Chinese gender, use gender('EN') to get the Female or Male.

birthday

return the birthday of the id owner. the format is like YYYY-MM-DD

province

return the province of the id owner. It's Chinese.

district

NOT suggested. because it's not perfect and takes memory. of course, use it if needed.
