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 the total transaction amount if that calculation includes sales taxes or tips. The law directly affects merchants, banks, and payment processors by banning fee structures that apply a percentage rate to the full gross dollar value of a debit or credit card purchase. Additionally, the bill sets strict limits on fees charged specifically for charitable donations, capping them at 0.2% for debit cards and 0.3% for credit cards. By defining these terms and restricting how fees can be calculated, the legislation aims to prevent networks from embedding taxes or gratuities into the base amount used to determine interchange charges.
