A lawsuit against major credit card companies, like Visa and Mastercard, has sent shockwaves through the financial industry. Interchange fees, which are transaction charges merchants must pay every time a customer uses a credit or debit card, have been a contentious issue in the retail industry. Retailers have argued that these fees are excessively high, unfair, and ultimately passed on to consumers through higher prices for goods and services. The lawsuit aimed at resolving a long-standing dispute over swipe fees charged to retailers has far-reaching consequences for consumers and businesses.
