# 常规交易

与两阶段模型不同，SHVA 支付服务的单阶段交易流程会在单一、连续的流程中处理并授权支付请求。这种简化的方式适用于无需中间用户交互的常规支付。

## 交易流程

要理解单阶段交易流程，请参考以下事件顺序：

![](https://mintcdn.com/nayax-44d6e37b/YZnJjomCaYdX9dh9/images/docs/single-phase-transaction/image1.png?fit=max\&auto=format\&n=YZnJjomCaYdX9dh9\&q=85\&s=24b8cc14bbdeddef51bea817c1609c5a)

以下是每个步骤的详细说明：

1. The client application (labeled as DC) initiates the transaction by sending a [`doTransaction`](/docs/integrate-pos-device/tweezercomm/israel-payment-methods/dotransaction-ashrait) request to the Nayax Device.
2. Nayax 设备通过插入、展示或刷卡的方式提示持卡人出示其卡片。
3. Nayax 设备向支付服务器发送授权请求。
4. 支付服务器处理该请求，并将授权响应发送回 Nayax 设备。
5. Nayax 设备将授权响应转发给 DC，完成流程中的支付部分。
6. At the end of the day, the DC sends a [`doPeriodic`](/docs/integrate-pos-device/tweezercomm/israel-payment-methods/doperiodic) request to the Nayax Device, which then communicates with SHVA to complete the day's batch process. The Nayax Device sends a [`doPeriodic`](/docs/integrate-pos-device/tweezercomm/israel-payment-methods/doperiodic) response back to the DC.
