What refers to the process of depositing payroll checks directly into a bank account?

The correct answer is Automatic check deposit, which refers to the electronic transfer of payroll funds directly into an employee's bank account, eliminating the need for physical checks. This process offers several advantages, such as quicker access to funds for employees, reduced administrative costs for businesses, and increased security since there's no need to handle checks.

Direct payroll is a term that might suggest payroll processing, but it does not specifically refer to the act of depositing checks electronically. Payroll services involve broader functions, including managing the entire payroll process, but do not define the electronic transfer concept specifically. Bank transfer, while related, generally covers all types of electronic transfers between accounts, not just payroll-related transactions.
