Answer:
Unless the credit card application form is pre-filled with personal information about the applicant, transmitting a form to a potential applicant does not create a security risk. If the completed application is never transmitted electronically from the applicant to the lender, but rather is printed on paper and sent through the U.S. mail, then "fill it out online" is a misnomer. In this case, there would be no security risk since the applicant's personal information never leaves his/her computer.
