+# PAYBACK Points
+![PAYBACK Points Widget Preview light](https://raw.githubusercontent.com/ThisIsBenny/iOS-Widgets/main/PAYBACK-Points/previewLight.jpeg)
+
+This widget shows you your PAYBACK points.
+
+Notice: PAYBACK points will be cached and updated only every 12 hours.
+
+[[Download]](https://raw.githubusercontent.com/ThisIsBenny/iOS-Widgets/main/PAYBACK-Points/PAYBACK-Points.js)
+
+## Setup
+Set the customer number and your password, separated by `;` to the Widget Parameter.
+
+![Setup](https://raw.githubusercontent.com/ThisIsBenny/iOS-Widgets/main/PAYBACK-Points/setup.jpeg)
+
+## Troubleshooting
+* The widget will be recognized as a bot from time to time and therefore cannot update the points. To solve the problem, you have to execute the script via the Scriptable App to solve the captcha
