IdParser.Core 2.0.0-alpha2

IdParser.Core

This is a fork of Connor O'Shea's IdParser library. Big thanks to him for all of his work.

The main changes I made are:

• Dropped support for .NET Framework. If you need that, please use the original IdParser.
• Supports only .NET 6 and above. If you need support for earlier versions of .NET/.NET Core, please use the original IdParser.
• The parser classes are now static and no longer instantiated by Activator.CreateInstance. This reduced memory allocations per call considerably, and also sped things up.
• The Abbreviation, Country, and Description attribute values are now cached so that we don't have to repeatedly use reflection to get their values.
• Unhandled parsing exceptions are now rethrown, regardless of what the caller passes for the validation level (None or Strict).
• Where possible, modernized the code base to use newer framework and language features, such as Span<T>.
• The return value of Parse is now an object that returns both the ID card and a collection of any unknown element Ids.
• Parse now accepts an optional TextWriter parameter. When not null, the library will log to the TextWriter.

The original README follows, slightly modified to match this updated version of the library.

ID Parser

ID Parser can be used to parse AAMVA-compliant driver's licenses and ID cards into objects that you can work with. More information on the versions of the AAMVA standard can be found here. More information on the D20 Data Dictionary can be found here.

Usage

1. Include the using

using IdParser.Core;

2. Then you're off to the races!

var parseResult = Barcode.Parse(barcode);
Console.WriteLine(parseResult.Card.Address.StreetLine1); // "123 NORTH STATE ST."
Console.WriteLine(parseResult.Card.IssuerIdentificationNumber.GetDescriptionOrDefault()); // "New York"

if (parseResult.Card is DriversLicense license)
{
    Console.WriteLine(license.Jurisdiction.VehicleClass); // "C"
}

More Examples

Take a look at the unit test project for more examples and usage.

Client

The IdParser.Core.Client project is a handy GUI application to help test and verify that an ID will be parsed correctly. The app works with both OPOS and HID keyboard emulation scanners.

FAQ

• I can't build IdParser.Core.Client. It's missing a required dependency. You need to have Microsoft POS for .NET installed. The Microsoft.PointOfService dll is GAC'd and will allow you to build and run the client app.

• The Height class has the wrong TotalInches or Centimeters. The AAMVA standard has no decimal places in the height subfile record. As a result, the conversion between inches and centimeters will be off.

• The library is throwing ArgumentExcpetions for every barcode I'm passing in. By default, all barcodes are parsed using the Strict validation level. All barcodes are expected to adhere exactly to the AAMVA standard as defined in the PDFs for parsing to succeed. This is the recommended level for scanners using OPOS. However, if HID keyboard emulation is used, especially when scanning using a web browser, the expected data can become malformed. You can try using the None validation level, however this is not guaranteed to work in all cases. Data elements may be skipped and exceptions may still be thrown.
