With the scanner in the Power BI app for iOS, you can now scan barcodes printed on products or shelves at your store, and in seconds see related records in your dataset and filter reports by barcode.

Here’s how:

1. Build your barcode enabled report
   Your dataset needs to contain a column with product codes, which you can load into Power BI Desktop. Select the table containing this column, go to modeling tab, and mark it as Barcode.
2. Use the scanner in the Power BI app for iPhone
   Log in to the Power BI app for iPhone, and open the scanner from the side menu. Scan the product barcode. Your report will automatically load and filter by the barcode value. If you have more than one barcode-enabled report, you can select the one you want to use from a list. To change the filter, use the small barcode icon on your report to open the scanner and scan additional codes.
