Is it discovery or punching in the security guard's salary?

There are two ways for security guards to pay wages: payment by discovery and punching in:

1, direct cash payment requires my signature. Security guards are generally sent by property management companies, and security guards sign labor contracts with property management companies. Property management companies are employers, and there should be a formal financial department to calculate and pay wages.

2. Bank card issuance is a common way adopted by companies. After an individual goes to the bank to apply for a bank card, the company directly enters the card within the agreed time every month.
