625 ILCS 5/18a-501
Unauthorized vehicles removed and stored by a commercial vehicle relocator in compliance with this Chapter shall be subject to a possessory lien for services pursuant to the Labor and Storage Lien (Small Amount) Act, and the provisions of Section 1 of that Act relating to notice and implied consent shall be deemed satisfied by compliance with Section 18a-302 and item (10) of Section 18a-300. In no event shall such lien be greater than the rate or rates established in accordance with item (6) of Section 18a-200. In no event shall such lien be increased or altered to reflect any charge for services or materials rendered in addition to those authorized by this Act. Every such lien shall be payable by use of any major credit card, in addition to being payable in cash. Upon receipt of a properly signed credit card receipt, a relocator shall become a holder in due course, and neither the holder of the credit card nor the company which issued the credit card may thereafter refuse to remit payment in the amount shown on the credit card receipt minus the ordinary charge assessed by the credit card company for processing the charge. The Commission may adopt regulations governing acceptance of credit cards by a relocator.
