Please see below link and generate the parser to extract the information of driver License.

http://www.dol.wa.gov/external/docs/barcodeCalibration-EDLEID.pdf

I have make this decoder for ios app

here the code :

NSString *message=barcode.barcodeString;

    NSMutableArray *arrFixedData=[[NSMutableArray alloc]initWithObjects:@"DCS",@"DCT",@"DCU",@"DAG",@"DAI",@"DAJ",@"DAK",@"DCG",@"DAQ",@"DCA",@"DCB",@"DCD",@"DCF",@"DCH",@"DBA",@"DBB",@"DBC",@"DBD",@"DAU",@"DCE",@"DAY",@"ZWA",@"ZWB",@"ZWC",@"ZWD",@"ZWE",@"ZWF", nil];
    NSMutableArray *arrDriverData=[[NSMutableArray alloc]initWithObjects:@"Customer Family Name",@"Customer Given Name",@"Name Suffix",@"Street Address 1",@"City",@"Jurisdction Code",@"Postal Code",@"Country Identification",@"Customer Id Number",@"Class",@"Restrictions",@"Endorsements",@"Document Discriminator",@"Vehicle Code",@"Expiration Date",@"Date Of Birth",@"Sex",@"Issue Date",@"Height",@"Weight",@"Eye Color",@"Control Number",@"Endorsements",@"Transaction Types",@"Under 18 Until",@"Under 21 Until",@"Revision Date", nil];


    NSMutableDictionary *dict=[[NSMutableDictionary alloc]init];
    for (int i=0; i<[arrFixedData count]; i++)
    {
        NSRange range = [message  rangeOfString: [arrFixedData objectAtIndex:i] options: NSCaseInsensitiveSearch];
        NSLog(@"found: %@", (range.location != NSNotFound) ? @"Yes" : @"No");
        if (range.location != NSNotFound)
        {
            NSString *temp=[message substringFromIndex:range.location+range.length];

            NSRange end = [temp rangeOfString:@"\n"];
            if (end.location != NSNotFound)
            {
                temp = [temp substringToIndex:end.location];
                temp =[temp stringByReplacingOccurrencesOfString:@"\n" withString:@""];
                temp=[temp stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];

            }
            NSLog(@"temp data : %@",temp);
            [dict setObject:temp forKey:[arrDriverData objectAtIndex:i]];
        }
    }

    NSLog(@"Dictionary : %@",dict);

The barcodestring contains the data which are scanned from pdf 417.

Thanks

Here's the Decoder for Android

Here, The Parameter "data" contains the string which you have to scanned pdf417.

==========Properties=============
HashMap<String, String> myData = new HashMap<String, String>();

public final String Customer_Family_Name = "DCS", Customer_Given_Name = "DCT", Name_Suffix = "DCU",
        Street_Address_1 = "DAG", City = "DAI", Jurisdction_Code = "DAJ", Postal_Code = "DAK",
        Country_Identification = "DCG", Customer_Id_Number = "DAQ", Class = "DCA", Restrictions = "DCB",
        Endorsements = "DCD", Document_Discriminator = "DCF", Vehicle_Code = "DCH", Expiration_Date = "DBA",
        Date_Of_Birth = "DBB", Sex = "DBC", Issue_Date = "DBD", Height = "DAU", Weight = "DCE", Eye_Color = "DAY",
