推荐答案

STAN-通常由您的网络接口生成，以使其在每个联机消息请求中都唯一.

STAN - usually generated by your network interface to make it unique per online message request.

RRN-是与交易相关的参考，可以由POS系统，集成商环境生成，或者可以由所获得的/发行者系统在授权接口之后进行生成.取决于RRN生成方，使其具有唯一性(或在某些情况下保持相同)的责任可以在客户端或在授权机构端.

RRN - is the transaction related reference and can be generated by POS system, Integrator environment or the generation can be done behind the authorisation interface by the acquired/issuer systems. Depending of RRN generation side the responsibility to make it unique (or keep same for some cases) can be at the client side or at the authorisation institutions side.

用于跟踪交易流的两个值都用于链式交易，例如冲销，充值，完成等.

Both values required to trace the transaction flows and used for chained transactions like Reversal, Top-Up, Completion, etc.

区别在于事务标识符的层. STAN是网络层和消息参考. RRN是客户的集成层和交易参考.

The difference is the layer of the transaction identifier. STAN is the network layer and message reference. RRN is the customer's integration layer and transaction reference.

根据交易处理要求，它们可以在实践中混合使用.对于样本STAN可以是RRN的一部分.

They can be mixed in practice, depending of transaction processing requirements. For sample STAN can be a part of RRN.
