Beginning in calendar year 2021, for every scavenger sale held pursuant to Section 21-260 of this Code, the county collector may employ any electronic automated means that the collector deems appropriate, provided that any electronic automated bidding system so used shall be programmed to accept the highest cash bid made by an eligible tax purchaser. If the county collector conducts the scavenger sale using an electronic automated bidding system, no personal attendance by bidders will be required at the scavenger sale. If automated means are used, all hardware and software used with respect to those automated means must be certified by the Department and re-certified by the Department every 5 years.
