Credit cards are issued by banks to cardholders according to users' credit and financial resources. Cardholders do not need to pay cash when using credit cards, but will repay when the bill is dated.

There are two main reasons why it is difficult for security guards to apply for credit cards:

1, most security guards are migrant workers with strong mobility;

2. Most of them have low level of safety education and low annual income.

The above two items directly determine that banks will not issue cards to security guards from the perspective of risk.

However, local people who own their own houses and work as security guards usually get small credit cards issued by banks.
