With build 500 you can build a barcode scanning app that works on all your mobile devices and in your Chrome browser. PowerApps community, thank you for providing solid scenarios and further. It was key information for us to shape and focus our first version of barcode scanning. Please do keep up this great engagement to help us refine and mature the barcode scanning experience! It this blog post I’ll give you a quick intro on how to: • Configure the new barcode scanner control • Consume its outputs in conjunction with a data source (using our Common Data Model in this example) • Allow the app users to dynamically change key properties. • Key best practices and how to fine tune the barcode scanner parameters to device specific limitations. How does the barcode scanner work? As soon as you add a barcode scanner to your canvas you’ll quickly notice it looks a just like the camera control. Since the camera is in continues capture mode, the barcode scanner detects live the barcode in focus. This design makes the barcode scanner handle gracefully batch scanning scenarios. Here’s couple of key properties to get you familiar with the barcode control before starting our tutorial: Barcode specific properties Barcodedetection: Shows a live detection rectangle while searching for barcodes. When a successful scan occurs a red line highlights the barcode being scanned. ![]() BarcodeType: Used to instruct the scanner on the expected barcode type to recognize. Codabar, Code39, Ean, I2of5, Upc. Please refer to the “Barcode types supported” section of the article for more details. ScanRate: Number of scans per second. Mac emulator for windows online. ![]() By default, this is set to 60 scan per second for fast detection. On phones, this value needs to be lowered between 45 to 35. This is just to accommodate the device memory constraints while still providing a good scanning experience. Properties controlling the camera quality Zoom: Works just like the zoom feature of a camera. The default zoom is at 50, you can increase it to 70 or more to allow holding your phone to within the desired distance from the barcode (to accommodate tight spaces, etc) Brightness: helps add more light into the picture if you need to scan in dark conditions Camera: Set to the specific value of your device (1,2, 3) that selects the front or the back camera. Now that you are familiar with the barcode, let’s quickly get an overview of the tutorial steps: Using a barcode scanner in conjunction with a data source Step 1: Create an app from data using leveraging Common Data Model. Step 2: Customize the first screen to filter records based on barcode being scanned. Step 3: Fine tune the parameters of the barcode and try it out 1: Create an app from data using Common Data Model Let’s imagine I have an inventory of assets and I’ve labeled them all with Code39 barcodes for internal tracking. To keep the tutorial simple, I’ve stored description of the item is stored along in the very same table. To create this Entity, I went to web.powerapps.com clicked “New Entity” and named my table Equipment. The entity already has a field named “Title”, so I’ll quickly added “SerialNumber” and InStock fields as follows: Next I’ve opened it in Excel and added couple of records With the Equipment entity ready use, I’ve opened Studio and start creating and app from data using Common Data Model as Connection. Once I got the app generated I’ve switched the layout to have a status bar on the right side. To show inStock/outOfStock status as blue and red respectively, I used an If expression that switches the Fill color accordingly. Next, I’ve configured the fields in the gallery to point to “SerialNumber” and “title” as shown in the next picture: 2: Customize the first screen to filter records based on barcode scanning Let’s move to our next step of the tutorial where I’ll be adding a barcode scanner control that would filter from list of items to the item scanned. This would make managing the assets so much faster, no need to type in the code anymore! The barcode control is available under Insert>Media. The 12.3-inch, 2,736 x 1,824-pixel touchscreen hasn’t changed in size or resolution, and I measured its extreme brightness as identical to the I reviewed in 2016. Once added there is a key step in a successful application/ The scanner is feeding the live image from the camera stream and it is key to size the barcode control to the optimal value for your targeted devices. As general guidance, a size going below the half of the screen height is likely to provide a too low of an image quality for good barcode detection. Also using a full screen experience can be very costly on the memory consumption, particularly on iOs devices.
