In the case of a system described in paragraph (1) in which participation is not optional for households, the Secretary shall not approve such a system unless—

(A) a sufficient number of eligible retail food stores, including those stores able to serve minority language populations, have agreed to participate in the system throughout the area in which it will operate to ensure that eligible households will not suffer a significant reduction in their choice of retail food stores or a significant increase in the cost of food or transportation to participating food stores; and

(B) any special equipment necessary to allow households to purchase food with the benefits issued under this chapter is operational at a sufficient number of registers to provide service that is comparable to service provided individuals who are not members of households receiving supplemental nutrition assistance program benefits, as determined by the Secretary.
