23 CAR § 355-1602. Loss of communication

(a) If communications between a gaming device or a gaming device interface component and a system are lost, the gaming device or the gaming device interface component may continue to issue tickets/vouchers provided that, printed on the instrument, there is an authentication code derived by a hash, or other secure encryption method of at least one hundred twenty-eight (128) bits, that will: (1) Uniquely identify the wagering instrument; (2) Verify that the redeeming system was also the issuing system; and (3) Validate the amount of the voucher. (b) For cases where a suitable authentication code is not printed on the voucher, the system must print at most one (1) wagering instrument after the gaming device or gaming device interface component to system communications have been lost.
