Final answer:
Account numbers on credit card receipts should be truncated to prevent credit card fraud and identity theft. This security measure is mandated in the U.S. by the Fair and Accurate Credit Transactions Act (FACTA).
Step-by-step explanation:
Yes, account numbers on credit card receipts should be truncated. Truncating means only showing the last few digits of the credit card number. This is a security measure to help prevent credit card fraud and identity theft. By only revealing a portion of the credit card number, it becomes much more difficult for thieves to steal the full number and use it for unauthorized transactions. The Fair and Accurate Credit Transactions Act (FACTA), enacted in the United States, mandates that merchants must truncate credit card numbers on receipts provided to the cardholder at the point of sale. Violation of these standards could result in legal consequences and hefty fines for businesses.
