你在国外看到过哪些服务或应用，想过：为什么我们没有这些？
去年我在印度时，使用了UPI（统一支付接口）。支付或分账就像扫描二维码一样简单。每个商店都有这个系统，从街头小吃摊到餐厅，无一例外，使用起来非常顺畅。
在新加坡，我看到了数字身份系统的巨大潜力。填写表格、医疗服务、银行业务——感觉一切都只需一次登录就能完成。
而在美国，即使是一次短暂的医院就诊也可能花费数千美元。这让我不禁思考，为什么一些在其他地方显而易见且有效的基本服务在这里却缺失。
你在国外见过哪些看似理所当然的东西，但在你居住的地方却不存在？

When I was in India last year, I used UPI. Paying or splitting bills was as simple as scanning a QR code. Every shop had it, from street food stalls to restaurants. It just worked.<p>In Singapore, I saw how much could be done with the digital ID system. Filing forms, healthcare, banking—it felt like everything was one login away.<p>In the US, even a short hospital visit can cost thousands of dollars. It made me wonder why some basic things that clearly work elsewhere are missing here.<p>What have you seen abroad that felt obvious, but doesn’t exist where you live?
