Prohibits credit and debit card interchange fees in certain circumstances.

This New Jersey bill prohibits payment card networks from charging interchange fees based on a percentage of transaction amounts for both credit and debit cards. The law specifically targets fees that include taxes or tips, preventing networks from calculating charges on the total gross amount rather than just the base purchase price. Additionally, the bill sets strict limits on fees charged for charitable donations, allowing only very small fixed percentages for such transactions. These rules directly affect payment processors, banks, and merchants by restricting how interchange fees can be structured and calculated.
