DailyPay is a financial service that allows employees to access their earned wages before their regular payday. It works by integrating with an employer's payroll system to track the hours worked by employees. Employees can then request a portion of their earned wages through the DailyPay app, which is transferred to their bank account or a prepaid card. The service typically charges a small fee for each transaction, and the remaining wages are paid out on the regular payday.
