Just come to the bank. The staff will tell you the specific process. The problems you think of can also be thought of by the bank staff. Any citizen, even the blind, can apply for a bank card, not to mention that you are only disabled and illiterate. As long as they are alive, they have the same right to apply for a card as normal people. Just go to the bank counter to handle the specific operation process, and any domestic bank can handle it. Bring your ID card.
