Scanning High-Density Aztec Codes on Train Tickets

The Aztec Code is a popular choice for electronic ticketing in the transportation industry. It has been adopted by airlines, including IATA’s BCBP standard, as well as rail companies worldwide. 1

Scanning the Aztec Code Displayed on Mobile Phone Screens

Many airlines and rail companies send Aztec Codes to passengers’ mobile phones as electronic passes. The Aztec code is scanned by handheld scanners carried by on-train staff or at turnstiles to validate the ticket. Increasingly, tickets are being displayed on mobile phone screens rather than printed on paper. While this can be more convenient for customers, it can present some unique challenges when it comes to scanning the Aztec code. In this article, we’ll take a look at some of the challenges and how Dynamsoft SDK can help overcome them.

Challenges of Scanning Electronic Airline and Train Tickets

Large and high-density Aztec codes

Aztec codes are capable of storing a large amount of data in a small space, which makes them ideal for use on tickets where space is limited. High-density Aztec codes require a higher level of precision and resolution from the scanner. Additionally, it requires more advanced image processing algorithms to distinguish between each individual data point.

Glare and interference pattern on phone screens

Screens can be reflective, which can cause glare and affect the readability of the barcode. Additionally, if there is an interference pattern present, it could disrupt the pattern of the Aztec code, making it more difficult for the scanner to accurately read the code.

Illumination

The illumination of the screen can also affect the scanning process. The Aztec scanner SDK should be able to adjust to different lighting conditions.

Motion blur

If the phone or the barcode is in motion while the scan is being conducted, this can cause motion blur which can make the barcode difficult to read. The Aztec scanner SDK should be able to compensate for motion blur.

Battery life

Barcode scanning can be power-intensive and may impact the battery life of the device.

Solution: Dynamsoft Barcode Reader

With its advanced algorithms and image processing capabilities, Dynamsoft Barcode Reader can accurately read high-density Aztec codes even in challenging conditions. This means that ticket vendors and event organizers can rely on Dynamsoft Barcode Reader SDK to ensure that all ticket information is captured accurately and efficiently.
