One wonders if the chits could have the value cut into them the way the old checkwriter machines did---another layer of security, issue date would be definitive; counterfeiting would be extra difficult. This would also add to the disposability, as the punctures would add more wear-surface, degrading the chits quickly and making them less useful over time.
