After reading the relevant information of the original poster, it is possible to apply for a credit card, so there is no need to worry about this.
To apply for a credit card, you can go to the bank counter with your ID card and proof of income stamped by your employer, fill out a credit card application form and submit it to the bank, and then wait one to two months for the bank to approve the card. Send a card, activate it after you receive it, and you can use it for consumption.
You can also apply online to apply for a credit card by yourself, but you must remember to make sure it is true and valid when filling in the relevant information, because the bank will review the information online and may also call you back. Once the information is inconsistent, it may affect your credit card application.
The specific credit limit of the card is related to your income. If you provide additional proof of assets when applying for a credit card, such as deposits, property, vehicle equity, etc., the credit limit of the card can be increased. The minimum limit standards vary from bank to bank, but generally the minimum limit is no less than 1,000 yuan. In the situation you mentioned, the monthly income is 4,000 to 6,000 yuan. If the unit provides proof of income and it fully meets the bank's credit card processing standards, just find a bank to apply. The limit is about 5,000 to 10,000 yuan. I hope you can successfully apply for the card as soon as possible!
