Which types of transactions might require additional verification?

The correct choice emphasizes the need for additional verification during large cash transactions or certain credit card purchases due to the higher risk of fraud or discrepancies involved. Large cash transactions can attract attention and may signal potential money laundering or other illicit activities, making careful scrutiny necessary. Additionally, specific credit card purchases may require verification if they surpass a certain limit or if they are made using cards that have previously experienced suspicious activity.

This need for heightened verification helps protect both the business and the customers from fraudulent activities. Fast transactions below a certain threshold, like those under $20, typically do not raise concerns that warrant additional scrutiny, and not all credit card purchases demand further verification since many are processed seamlessly if they fall within normal transaction limits. Returns are typically handled according to store policy rather than requiring increased scrutiny unless there are red flags present.
