Iowa Zapper & Sales Suppression Law
Iowa has no statute specifically addressing automated sales suppression devices.
That does not mean suppression is lawful in Iowa. Conduct involving a zapper or phantomware may still be charged under general tax-fraud, false-return, or computer-crime provisions — those statutes simply do not name suppression devices specifically.
