According to the description of the situation, you have been paying back on time and you have established a good credit record in the bank. Just apply for a credit card now, which belongs to the bank's high-quality customers. The documents required to apply for a credit card are:

1. Identity certificate: the applicant's identity card with full capacity for civil conduct, age18 ~ 65;

2. Income certificate or work certificate: my salary certificate, bank current account, the original official work certificate issued by my work unit, the original work permit or business card with comprehensive information, the name of my work unit, the name of the applicant and the social security/medical insurance/provident fund certificates paid in the last three months.

3. Proof of financial resources: original or photocopy of salary record issued by the bank, income certificate issued by the unit, income tax withholding certificate, self-owned real estate license/house purchase contract/bank mortgage repayment schedule, self-owned car driving license, bank deposit certificate and other materials.

When handling credit cards, you should consider your financial situation. If you have a loan, you need to pay off your credit card every month. The repayment pressure may be heavier, so it is recommended to consider it carefully.
