1.1.6 Dynamic QR Code 动态桌码

> This section explains the "Dynamic QR Code" function, triggered by the "Order Code" button. It generates a unique ordering QR code to prevent unauthorized orders. The system supports two distinct operational models based on your backend settings: high-end service and time-limited buffets. 本节说明由“Order Code (点餐码)”按钮触发的“动态桌码”功能。它会生成唯一的点餐二维码以防止恶意或非店内人员下单。根据后台设置，系统支持两种截然不同的运营模式：高档服务餐厅与限时自助餐。

#### 1. High-End Service Workflow 高档服务餐厅模式
Suitable for traditional dine-in where guests are seated first. The QR code has no time limit and automatically expires when the table is closed and paid. 适用于客人先落座的传统堂食。二维码没有时间限制，在结账关台后自动失效。

1. **Open Table (开台落座)**: Seat the guests and open a table on the POS system. 1. **开台落座**：安排客人入座，并在 POS 系统上正常开台。
2. **Print Order Code (打印点餐码)**: On the right-side menu, click the **Order Code** button to print the QR code. 2. **打印点餐码**：在右侧功能菜单中，点击 **Order Code** 按钮打印出点餐二维码。
3. **Present to Guest (递交顾客)**: Place the printed QR code in an elegant holder and present it to the table for ordering. 3. **递交顾客**：将打印好的二维码放入精美的展示牌（或亚克力板）中，递交给该桌客人扫码点餐。
4. **Reprinting Logic (重新打印机制)**: If you need to print it again, clicking **Order Code** will generate a fresh QR code and instantly invalidate the previous one to ensure security. 4. **重新打印机制**：如果再次点击 **Order Code** 打印，系统会生成一张全新的二维码，并自动让原本的旧码立即失效，以确保安全。![](/media/202605/2026-05-21_190129_5379990.6789602971196511.png)

#### 2. Buffet Service Workflow 自助餐模式

Suitable for all-you-can-eat scenarios where guests pay upfront at the counter. The printed QR code has a strict expiration time. 适用于客人在前台先结账（或先确定套餐）的自助餐场景。打印出的二维码具有严格的有效时间。

1. **Select Package & Pay (选择套餐与结账)**: At the front counter, guests confirm their buffet package and make the payment. The system then grants access to the corresponding all-you-can-eat menu. 1. **选择套餐与结账**：客人在前台确认需要享用的自助餐套餐并付款，系统随之开放对应的免费任点菜单权限。
2. **Print Order Code (打印点餐码)**: Click the **Order Code** button at the POS. The designated printer will print a QR code ticket explicitly displaying the expiration time (e.g., valid for 3 hours). 2. **打印点餐码**：在收银台点击 **Order Code** 按钮。指定的打印机会打出点餐二维码小票，且小票上会明确显示该二维码的有效时间（例如：限定 3 小时内有效）。
3. **Seat & Order (落座点餐)**: Guests take the QR code ticket to their table to order. Once the time limit is reached, the QR code automatically becomes invalid and no more items can be ordered. 3. **落座点餐**：客人拿着二维码小票落座并扫码吃饭。一旦设定的时间耗尽，二维码将自动失效，系统会自动阻断顾客继续加单。
4. **Reprint or Extend (补打与续费机制)**: If you click **Order Code** again, the system will prompt a choice: you can print using the *original remaining time* (ideal if the guest lost their ticket) or generate a *new expiration time* (if the guest paid to extend their buffet time). 4. **补打与续费机制**：如果再次点击 **Order Code**，系统会要求您进行选择：您可以选择按照*原有的剩余时间*打印（适用于客人弄丢了小票需要补打），或者重新生成*新的有效时间*（适用于客人续费继续就餐）。![](/media/202605/2026-05-21_185919_3637720.8122000070415905.png)

### 2. Frequently Asked Questions (FAQ) 常见问题

**1. QR Code Expiration / 动态桌码失效机制**
* **Q: Will the Dynamic QR Code leak and allow people outside the restaurant to place fake orders?** **Q：动态桌码会泄露导致不在店里的人恶意下单吗？**
 * **A:** No. The Dynamic QR Code is highly secure. In high-end restaurants, the code automatically dies the moment the table is checked out and closed, or if a new code is printed. In buffet mode, it strictly expires based on the preset countdown. Old codes cannot be reused. **A**：不会，动态桌码非常安全。在高档餐厅模式下，只要该桌结账关台，或重新打印了新码，旧码瞬间作废；在自助餐模式下，时间一到立即失效。过期的旧码完全无法被重复利用。

**2. Printer Settings / 点餐码未打印排障**
* **Q: I clicked "Order Code", but no QR code ticket was printed out. What should I do?** **Q：我点击了“Order Code (点餐码)”，但是打印机没有打出任何二维码小票，我该怎么办？**
 * **A:** First, check if the POS printer has paper and is functioning. Second, verify in your backend settings that you have correctly assigned a designated printer to the "Order Code" printing task. **A**：首先，请检查收银机旁的打印机是否有纸且运作正常。其次，请前往后台设置中检查，确认您是否已经为“点餐码”任务正确配置了对应的接单打印机。
