什么是QR码生成器?

QR码(Quick Response,快速响应码)是一种二维条形码,手机可以即时扫描。它被广泛用于菜单链接、分享联系人、WiFi凭据、支付URL和活动签到。QR码很稳健:它们内置了纠错功能,因此即使部分损坏或被遮挡也仍然可读。对于印刷材料,请以高分辨率生成,并在大规模印刷前进行测试。

常见使用场景

  • Print a QR code on a restaurant table tent that opens the digital menu when scanned.

  • Add a code to a conference badge or flyer that links to an event schedule or registration page.

  • Put a QR code on product packaging pointing to setup instructions or a warranty page.

  • Drop a scannable link into a slide deck so the audience can open a demo on their phones.

  • Generate a code for a payment or donation URL to display at a market stall or checkout.

  • Create a quick code linking to your portfolio or LinkedIn for in-person networking.

常见问题

一个QR码最多能容纳多少数据?
最多4296个字母数字字符或7089个数字。对于URL和短文本来说,容量绰绰有余。
QR码会过期吗?
静态QR码(如这里生成的)永不过期。来自支付服务的动态QR码可以编辑,但需要账户。
