Step-by-step explanation:
Card networks classify merchants in unexpected ways for various reasons. One reason is to ensure that transactions are accurately categorized and processed. For example, a merchant may be classified differently depending on the type of goods or services they offer. Another reason is to determine the appropriate fees and charges associated with processing transactions. Some merchants may be considered high-risk, which can result in higher fees. Lastly, card networks may classify merchants differently based on their reputation and compliance with regulations. This helps protect consumers and maintain the integrity of the payment system.
