To remain compliant:
- Register with card brands (e.g., Visa, Mastercard) at least 30 days before starting.
- Display clear signage at your entrance, point of sale, and online checkout.
- Communicate the surcharge before completing a phone order.
- Cap the surcharge at your actual processing cost or 3%, whichever is lower.
- Only apply surcharges to credit cards, not debit or prepaid cards.
