 It's difficult to type long text on mobile devices, but if that text is encoded in a barcode, we can use the sdk to read the barcode and automatically enter the text.
 
-The following code shows how to automatically invoke the sdk to read a barcode and fill in an input box.

-<input id="input-to-fill" type="text" readonly="true" placeholder="Barcode Result">

 # Read the PDF417 Barcode on the Driver's License
 
 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.
 
 The following official sample shows how to use the sdk to read and extract driver's license information.
