23 CAR § 355-1601. Generally

(a) A ticket validation system may be entirely integrated into an online monitoring system or exist as an entirely separate entity. (b) Payment by ticket printer as a method of credit redemption on an EGS is only permissible when the EGS is linked to an approved ticket validation system. (c) Validation information shall be communicated from the system to the EGS using a secure communication protocol. (d) This subpart concerns bidirectional ticket validation system-specific requirements where a ticket validation system that is independent of an online monitoring system would also require the security and integrity standards previously outlined within this document, would also apply.
