预授权（以色列）

Tweezercomm 的预授权交易会根据支付服务器的响应进行处理、授权，并最终结算或取消。此流程还包括用于处理错误的弹性机制。

交易流程

要理解预授权交易流程，请参考以下事件顺序：

以下是每个步骤的详细说明：

The client application (POS) sends a doTransaction() request to the Nayax Device with a parameter (Trancode=2) to initiate a pre-authorization.
持卡人插入、展示或刷卡。
Nayax 设备与支付服务器通信以执行预授权。
The payment server responds, and the Nayax Device relays the Authorization result back to the POS.
At a later time, the POS sends another doTransaction() request, this time with a parameter (Trancode=3) to initiate the completion of the pre-authorized transaction.
Nayax 设备与支付服务器通信以完成该交易。
The payment server responds with a Completion result, which the Nayax Device sends back to the POS.
At the end of the day, the POS sends a doPeriodic() request. The Nayax Device communicates with the payment server to perform the settlement of the day’s transactions and sends a doPeriodic() result back to the POS.
