How dynamic QR codes work

When you create a dynamic code, SnapQR generates a short URL such as snapqr.link/x7Kp and encodes that into the QR pattern. Scanning triggers an instant redirect (an HTTP 302) to whatever destination you've configured. Because the printed pattern only ever contains the short URL, you can repoint it as often as you like — the paper never changes, the destination does.

Each scan is recorded on the redirect hop: timestamp, device type, operating system, approximate location from IP (the IP itself is never stored), and referrer. That single redirect is what turns a printed poster into a measurable marketing channel.

Dynamic QR code FAQ

Are free dynamic QR codes going to stop working later?

No. SnapQR dynamic codes don't expire and don't get watermarked. Unlike trial-based services, there is no plan that runs out.

How many times can I change the destination?

Unlimited. Every change applies instantly to every printed copy.

Do I need an account to manage my code?

No — you get a private manage URL when you create the code. Anyone with that URL can edit the code, so treat it like a password. Your codes are also remembered on your device under My codes.

Can I turn a code off?

Yes — pause it anytime from the manage page and scans show a friendly “deactivated” notice; resume whenever you like.

常见问题

SnapQR 真的免费吗?有什么隐藏条件吗?

是的——创建二维码、动态二维码、短链接和分析都是 100% 免费的,无需账户。没有水印,二维码也不会过期。

静态二维码将内容直接编码在图案中,永远无法更改。动态二维码编码的是一个你可控制的短跳转网址,因此你可以在打印后更改它的指向,并跟踪每一次扫描。

打印后如何编辑二维码?

创建动态二维码时,你会获得一个私密的管理网址。打开它,输入新的目标地址并保存——每一份已打印的副本都会立即指向新页面。

我可以给二维码添加徽标吗?

可以。在设计面板中上传任意图片——它会以高纠错级别嵌入到中心,因此二维码仍能可靠扫描。徽标完全在你的浏览器中处理。

我能获得哪些分析数据?

每个二维码:总扫描次数、独立访客、扫描随时间的变化、设备类型、操作系统、浏览器、国家、城市和来源——并支持 CSV 导出。IP 地址绝不会被存储。

我可以下载哪些文件格式?

最高 4096 px 的 PNG(在 300 DPI 下约为 13 英寸)以及可无限缩放的 SVG 矢量图——两者都适合专业打印。

我可以为短链接使用自己的域名吗?

可以——将 CNAME 指向 snapqr.link 并通过我们的 API 注册该域名。HTTPS 证书将自动签发。
