什么问题该说什么What to include
某个字段解析错了A field decodes incorrectly
请附上报文片段（务必先把卡号等持卡人数据脱敏）、你选的卡组和编码、以及你认为正确的结果。这类问题优先处理。
Send the message fragment — mask the PAN and any other cardholder data first — plus the scheme and encoding you selected, and what you expected instead. These get priority.
想支持某个卡组或数据域Support for a scheme or data element
说明是哪个卡组、哪个域，以及它的布局依据（请勿发送任何保密规范，公开文档或你自己构造的样例即可）。
Tell us which network and which element, and where the layout is documented. Please do not send confidential specifications — public documentation or your own synthetic sample is enough.
文章内容有误Something in an article is wrong
指出是哪一篇、哪一段，以及依据。技术内容出错会误导别人排查，这类反馈非常欢迎。
Point to the article and the passage, with your source. Wrong technical content misleads people who are debugging production issues, so these corrections are genuinely welcome.
合作与商务Partnerships and business
内容合作、工具定制、企业内部部署等，邮件说明来意即可。
Content collaboration, custom tooling or an internal deployment — just say what you have in mind.

关于这个站About this site
想了解这个工具是谁做的、数据依据是什么、以及我们与卡组织的关系，请看 关于页面。数据处理方式见 隐私政策——简单说：你粘贴的报文完全在浏览器本地解析，不上传服务器。For who builds this, where the field definitions come from, and our (lack of) affiliation with the card networks, see the About page. For how data is handled, see the Privacy Policy — in short, what you paste is parsed entirely in your browser and never uploaded.
