支付通信在英语中可以称为 "payment communication"。

这个词组的来源源自于英文的两个单词："payment" 和 "communication"。"Payment" 指的是支付，"communication" 指的是通信。将这两个单词组合起来，就可以描述支付时发生的通信，也就是 "payment communication"。

一些英文例句及其中文翻译如下：

Payment communication can be done through various channels, such as onpne banking, mobile apps, or in-person transactions.
(支付通信可以通过多种渠道进行，例如网上银行、手机应用程序或者面对面的交易。)

Payment communication often involves the exchange of financial information, such as account numbers and transaction details.
(支付通信通常涉及金融信息的交换，例如账号和交易细节。)

Payment communication can be secured using encryption techniques to protect against unauthorized access or interception.
(可以使用加密技术来保护支付通信，以防止未经授权的访问或拦截。)
