NJ Business Information

 - Credit Card Fees: Businesses can charge customers an extra fee for paying with a credit card, but the fee cannot be more than what the business pays to process the payment.
- Let Customers Know: Businesses must clearly tell customers how much the fee is before they make a purchase.
- Signs and Notices: Stores must display the fee at the entrance and checkout area. Restaurants must show it in customer service areas and on all menus, including online menus.
- Online and Phone Payments: Customers must be told about the fee before completing an online or phone payment.
- Debit and Gift Cards: These specific rules only apply to credit cards, but businesses must still clearly explain any other fees before a purchase.

Bottom Line: Charging a credit card fee is optional. If your business chooses to charge one, make sure customers know about it ahead of time and that you're not charging more than your actual processing costs.
