The PDF417 barcode on an AAMVA compatible driver's license contains a lot of information which is encoded following the DL/ID Card Design Standard. Together with a simple parse function, we can use the SDK to read and extract the information.

When the SDK picks up a barcode in video stream, it will highlight them with built-in style automatically. But it is also possible to show the text of the barcode on the video with the help of the function 'convertToPageCoordinates()' or 'convertToClientCoordinates()'.

## Locate an Item via Barcode
31+
32+
Searcing for a specific item among numerous identical boxes can be challenging. However, with the Dynamsoft Barcode Reader (DBR) SDK, we'll be able to locate the item quickly by scanning through the barcodes.
33+
34+
The following sample demonstrates how to utilize the SDK to find an item using a barcode among many barcodes.
35+
36+
Additionally, this sample demonstrates how to utilize the SDK to fill out form fields, creating a custom UI with [Dynamsoft Camera Enhancer (DCE)](https://www.dynamsoft.com/camera-enhancer/docs/core/introduction/index.html), and using DCE to draw shapes/images on the CameraView to create indicators for each barcode that has been detected!
