Forenzapper commonly referred to simply as “zapper,” is a type of software used to manipulate point-of-sale (POS) system records. Its primary function is to alter sales data to underreport revenue, thereby reducing the amount of tax owed by a business. This software can be run surreptitiously, often from a USB drive, making it difficult to detect. The use of Forenzapper is illegal and can lead to significant penalties, including hefty fines and criminal charges, as it constitutes tax evasion​
