QR Code Scanning in POS

+

Scans QR codes via device's camera.

+
+
+
+ +
+
+
+
+ +
+
+
+

+ New Button to start scanning +

+
+
+
+ +
+
+
+

+ Click QR Scan and make QR Code under camera as on the video below (open it in a new Tab, if the video is not played). + Once QR is scanned, camera is closed and next action will be + done automatically +

+
+
+ +
+
+
+ +
+
+
+ +
+ Result after scanning depends on other modules. For example, with module WeChat Payments in POS scanning will result registering qr-based payment. +
+ +
+
+
+ +
+
+
+ +
+ For mobile devices we recommend to use POS Mobile UI module. +
