in theory it could return a quilt to its rightful owner but odds are the person who stole it isn't going to get the quilt scanned.
a microchip on the other hand would be nice to retain data on the quilt thru out time.
wouldn't it be wonderful if the quilts made during the civil war had microchips that would detail the makers life and the inspiration behind the quilt.
i think that would be a wonderful idea for current quilters to do on their heirloom quilts.
