N.Y. Comp. Codes R. & Regs. tit. 9 § 5317.4
This Part does not govern MCS requirements for any other form of monetary transaction. Such standard also does not govern advanced bi-directional communication protocols (i.e., EFT, AFT, bonusing, promotional, system-based progressives, features that use an RNG, etc.) that support credit transfer between gaming device and MCS. Such standard supports only one-way communication of events originated at the gaming-device level to the MCS, with the exception of the voucher validation system requirements that are incorporated within section 5317.39 of this Part. Such standard does not exclude gaming devices that operate with player account cashless transactions for the purpose of mandatory communication of security events and electronic meters. All relevant monetary transactions at the slot machine level are handled via electronic transfer through a secure communication protocol. These device types shall meet the applicable requirements set forth herein, specifically governing metering information and significant events in addition to other commission standards that may apply.
