According to Article 44 of the "Regulations on the Supervision and Administration of Credit Card Business of Commercial Banks", card-issuing banks are not allowed to issue credit cards (except supplementary cards) to customers under the age of 18. There is no indication that people over 80 years old can apply for credit cards, so according to the management regulations, people over 80 years old can apply for credit cards because there is no upper age limit.
