Possible Cause:   Solution: Although your device says it's connected, you are in the wrong mode.   If you are scanning into an application such as Shopify, Square or Zettle by Paypal, restart the host device and pair your reader to your host in Application Mode using Socket Mobile Companion App  (AU, EMEA, UK). Watch : How to pair Using Companion App . If you are scanning into an application such as Notes, MS Word, MS Excel or you are scanning into a text field in a web browser, please follow these instructions  (AU, EMEA, UK).   Possible Cause:   Solution: The barcode reader is too close / too far from the barcode or the scanning angle is incorrect.   Practice scanning barcodes from different distances and angles. Reading distance may vary according to barcode size and aspect ratio, symbology, label type and reading angle.     Possible Cause:   Solution: The barcode is either incorrectly formatted, damaged or badly printed.   Try to scan a barcode that is correctly formatted, clearly printed and of good quality.   Possible Cause:   Solution: The symbology function is disabled or not supported by the barcode reader.   Enable symbology. If you don't know the barcode symbology, please contact us at support@socketmobile.com.   Possible Cause:   Solution: No application is activated to receive scanned data.   Open an application (e.g. Notes). Position the cursor where you wish to enter data and try scanning again.
