225 ILCS 454/20-25
Any person who (1) delivers a check or other payment to the Department that is returned to the Department unpaid by the financial institution upon which it is drawn shall pay to the Department; or (2) presents a credit or debit card for payment that is invalid or expired or against which charges by the Department are declined or dishonored, in addition to the amount already owed to the Department, a fee of $50. The Department shall notify the person that payment of fees and fines shall be paid to the Department by certified check or money order within 30 calendar days of the notification. If, after the expiration of 30 days from the date of the notification, the person has failed to submit the necessary remittance, the Department shall automatically revoke the license or deny the application, without hearing. If, after revocation or denial, the person seeks a license, the person shall apply to the Department for restoration or issuance of the license and pay all fees and fines due to the Department. The Department may establish a fee for the processing of an application for restoration of a license to pay all expenses of processing this application. The Secretary may waive the fees due under this Section in individual cases where the Secretary finds that the fees would be unreasonable or unnecessarily burdensome.
