Original Summary

Wallet-marketing tools charge small businesses a monthly fee for this: customers add a card to their Apple/Google Wallet, and the shop can send them notifications on their lock screen. No app needed. Turns out the whole thing is just a wallet pass that gets updated, so I rebuilt it and put it on GitHub: Design your card and print the QR code People add it to their wallet in one tap (no app, no signup) Type a message → it shows up on their lock screen You also get a subscriber count, message history, and QR codes per placement so you can see which one works best. First test on my iPhone worked (video). You can deploy it on Vercel in one click or run it with Docker. If you'd rather not host it yourself, there's a waitlist for a hosted version in the repo.

中文标题： 我构建了一个免费、开源的通过 Apple Wallet 发送锁屏通知的方法（企业每月为此付费）

作者重建了付费 Wallet 营销工具的能力：顾客把卡片加入 Apple/Google Wallet 后，商家可发送锁屏通知，无需应用。流程包括设计卡片并打印二维码、一键加入钱包、输入消息后在锁屏显示；还提供订阅者数、消息历史和按投放位置区分的二维码，首次 iPhone 测试成功。可一键部署到 Vercel 或用 Docker 运行；仓库还提供托管版等待名单。作者询问经营咖啡馆或商店的人是否会使用。
