When moneys are sent to the treasury, by express or otherwise, it shall be the Treasurer's duty to obtain the Comptroller's order, hereinbefore required, before receipting therefor. The order required under this Section may be prepared by any magnetic or electronic technology as determined to be in the best interest of the State by the Comptroller.
