IC-Card Authentication Trouble

What kinds of characters or letters can I use in my PIN?

You can use Romanized letters, numbers, and symbols. For Romanized letters, you can use capital or small letters. Mix them with numbers, and create a string of characters whose coded meaning cannot easily be discerned. By mixing in symbols, you can create an effective password of a string of characters that will be difficult to crack. Please refrain from using a PIN composed of characters from which your name and ID can be easily inferred, such as dictionary vocabulary entries, the names of famous persons, or proper names.
