If you don't have a fixed office, you can try to apply for a credit card, but ordinary banks can easily refuse you, because in the traditional credit card processing, you need to be at least 18 years old, have full capacity for civil conduct, have a stable source of income and a stable work unit.

If there is no fixed unit, it is best to have other fixed assets such as real estate or cars; If there is a stable source of income, you can submit a bank statement application to the bank. Generally speaking, your income source is relatively stable, and the application success rate is still very high.
