>Discounts to Customers
A PCN cannot stop you from offering your customers a discount or another incentive for using a certain method of payment, as long as you offer it to all your customers and disclose the offer clearly and conspicuously. For example, you can offer your customers a discount or a coupon if they pay with cash or a debit card rather than a credit card.
Still, that kills any incentive for fee competition between cards - they all share the benefits of being convenient and face little pressure to change the fee structure.
