19 Del. Admin. Code §§ 1324-2.0
Delaware's Wage Payment and Collection Act requires the payment of wages to employees in lawful money or checkspayable on demand, "provided suitable arrangements are made by the employer for cashing such checks for the full amount of the wages due at a bank or other business establishment convenient to the place of employment. Employers may comply with this requirement by issuing a payroll debit card which provides the functional equivalent of cash or a check. It is the employers' responsibility to effectuate a payroll debit card system which will allow full payment of wages on the employee's regular payday and without cost to the employee. Employers may use a pre-paid debit card or general payroll fund account to establish suitable arrangements for converting wages into employee's disposable income.
