实用问题，简单说明。
访客需要安装应用吗？
不需要。体验直接在手机浏览器中运行。访客扫描二维码、允许相机访问后即可进入 AR 场景。
目前支持哪些应用场景？
商务名片、房地产和博物馆均有独立的创建流程，平台还将持续支持更多模板。
材料印刷后还能修改内容吗？
可以。二维码和印刷识别图保持不变，您可在控制台更新链接、媒体、可售状态、展品或其他内容。
手机不支持 AR 时会怎样？
访客会看到包含关键信息和操作的响应式备用体验，确保每次扫码仍然有价值。
How do monthly credits work?
Your monthly credits are shared across all published projects and reset each billing period; unused monthly credits do not roll over. Existing credits from before subscriptions are retained until used. Each template shows its credit rate before you use it.
到底什么算一次图像扫描？
You pay for attention, not for page loads. Opening the QR code is free — a visitor who scans it and walks away costs you nothing. You are charged once for each different printed image a visitor actually points their camera at, at your template's credit rate: a business card with a printed back side can be two scans, a museum tour one per exhibit scanned. Pointing the camera at the same image again in the same session is free, and a visitor whose phone cannot run AR sees the fallback page and counts as one scan.
