Barcode house

I came across the "Barcode House" along the winterwalk which is located in Merano on the right side of the Passirio river. This house has been nicknamed so because of the huge painted barcode that can be seen on two of its external walls. On the front wall, next to the drawing, you can also read the small vertical writing "Klasse 3A Wisslyz Meran 1998" which seems to recall a 1998 intervention by the students of the local scientific high school. Over the years the bar code indicated on this wall has been changed at least once from 485563-209758 to 485562-061007 but the reason for its presence, and even more so for this replacement, remains a still unsolved mystery: a simple decorative intervention or a hidden message to decipher?
