The use of electronic funds transfer or any other payment means by the state shall not create any rights that would not have been created had an individual state warrant been used as the payment medium. The use of electronic funds transfer or any other individual payment to the state shall not create any rights that would not have been created had an individual check been used as the payment medium to the state.
