Some U.S. banks are unhappy with the transaction fees that Apple is charging its Apple card, the source said.

Among them are JPMorgan Chase, Capital One and Bank of America. They have already contacted Visa and asked the company to change the way it handles some Apple card transactions. And Visa allegedly already agreed to do it next year. The company is currently in talks directly with Apple, while some sources say the Cupertino giant’s management is unhappy with the proposed changes.

At the same time, if Apple and Visa reach an agreement, the former will stop receiving fees for recurring transactions such as subscriptions.

At the moment, Apple charges banks a small fee for every transaction that uses an Apple card through Apple Pay. The commission varies by country. For example, in the US, Apple charges 0.15% for each credit card transaction and 0.5 cents for debit card transactions.
