This tutorial will introduce you to the classes and methods for both reading and writing AAMVA-compliant barcodes from Driver’s Licenses.

This article is in the Product Showcase section for our sponsors at CodeProject. These articles are intended to provide you with information on products and services that we consider useful and of value to developers.

Introduction

If you’ve renewed your driver’s license any time in the last few years, you have likely noticed an increase in its visual complexity. Many governing bodies have made significant strides towards making forgery more difficult. The unfortunate side-effect from that positive change is that traditional recognition algorithms are more difficult with the many colors, backgrounds, holograms, and layouts.

Thankfully, new driver’s licenses also have PDF417 barcodes on them, and in North America, follow specifications laid out by the American Association of Motor Vehicle Administrators (AAMVA). These barcodes are small, error resistant, and can encode a lot of information.

This tutorial will introduce you to the classes and methods for both reading and writing AAMVA-compliant barcodes from Driver’s Licenses.

Reading AAMVA Barcodes

Since Driver’s Licenses are so broadly accepted as forms of identification, there are a wealth of opportunities for reading the information from them. We covered those concepts in an earlier white paper on Capturing Customer Information from Driver's Licenses, so we won’t repeat them here. That paper also discussed using the PDF417 barcodes before they were regulated by AAMVA. Since then, LEADTOOLS has added a new AAMVAID class which does all the field parsing for you.

What’s the big deal? Take a look at the raw data for an AAMVA barcode:

Where’s the name? Or the birthdate? Do you need to calculate if this person is over 21 and legally allowed to make a purchase? With LEADTOOLS, you can get that kind of information in beautiful, strongly typed properties:

Writing AAMVA Barcodes

There may be fewer reasons for generating AAMVA barcodes, but every motor vehicle agency in every state or province in the United States, Canada, and Mexico needs the ability to print them on the licenses they issue. Naturally, you can’t just print any old barcode onto licenses and IDs. As with most specifications, they are hard to follow and can cause a significant development roadblock due to the R&D requirements. LEADTOOLS simplifies this in two ways: generating the AAMVA string and creating the PDF417 barcode.

First, you need to convert your customer data into a valid AAMVA string value. To aid in this process, LEADTOOLS provides the AAMVAIDBuilder class. The builder will help organize the data and output it conforming to the 2016 AAMVA CDS. Here we initialize the AAMVAIDBuilder, add some information and then use the Build function to generate the AAMVAID object:

Now that our customer’s information is correctly encoded for AAMVA, we will create the PDF417 barcode. Thanks to LEAD’s nearly three decades of experience in with raster and document imaging technologies, this process is even simpler than writing the AAMVA string despite the barcode’s greater complexity. Here we generate the BarcodeEngine, set a few options to help the proportions make AAMVA happy, and LEADTOOLS takes care of the rest. In this simple case, we simply created a blank image using the calculated bounds of the barcode:

As a check, we’ll load the image back into the Main Barcode demo like before and read the data.

Conclusion

LEADTOOLS has a history of staying on the forefront of document imaging and recognition technologies like OCR, Forms, Barcode, and PDF. Driver’s licenses and IDs have become far more complex, yet better regulated with the adoption of AAMVA barcodes. LEADTOOLS will stay a viable option for developers wanting to quickly and easily create software to read and write identification data stored in AAMVA barcodes.

OMNI-DIRECTIONAL HANDS-FREE PRESENTATION IMAGERS

Whether you need to scan printed bar codes on paper labels or mobile bar codes on the screen of a mobile phone, with the DS9208, you’ll be ready. You get the versatility to scan any 1D or 2D bar code — from the printed labels in retail that identify product and pricing at the register to mobile coupons, mobile gift and loyalty cards, boarding passes and even theater tickets. And the DS9208 provides all the features you need to keep your workers productive: industry-leading scanning speed; true point-and-shoot scanning simplicity — no need to align bar code and scanner; and hands-free and handheld flexibility.

BOOST CUSTOMER SERVICE, LOYALTY AND REVENUES WITH MOBILE BAR CODES

Convenience is driving your customers to store boarding passes, event tickets, mobile gift and loyalty cards as well as mobile coupons on their cell phones, where they are always available and easy to find — unlike their physical counterparts. But if you can’t scan the mobile bar codes, convenience turns into a hassle that could result in a lost customer. With the DS9208, you are ready to complete the mobile bar code transaction chain, able to scan virtually any mobile bar code on any type of display — protecting service levels and customer loyalty.

A GO ANYWHERE DESIGN AND TINY FOOTPRINT

Maybe your retail store has a trendy decor. Or maybe your counter space is extremely limited. The DS9208 sports a new sleek contemporary design that is at home in either environment. And with the most compact footprint in this class, the DS9208 can fit in the most space constrained areas — from the POS in a boutique to the ticket window at a train station.

A SMART INVESTMENT AND A LOW TOTAL COST OF OWNERSHIP (TCO)

The DS9208 not only helps you make money, it helps you save money. The device is so intuitive that training — and training-related costs — are virtually eliminated. Right out of the box, the DS9208 can read the most common 1D and 2D bar codes on a wide variety of surfaces — from paper labels to cell phone displays. Integrated Electronic Article Surveillance (EAS) functionality eliminates the need to purchase and manage a standalone EAS system.
