What is a common application of a 2D scanner?

A common application of a 2D scanner is to read passports at airports. This process involves scanning the information page of a passport, which is a flat document containing both text and a photo, to capture vital identification details such as the passport number, name, and other personal information. The use of 2D scanners in this context enhances the efficiency of border control and identity verification processes, allowing for quick and accurate processing of travelers.

While the other options involve scanning technologies, they do not specifically utilize 2D scanners in the same mainstream way as airport passport readers. Creating 3D models typically requires specialized 3D scanning equipment rather than a 2D scanner. Reading QR codes and scanning barcodes can involve both 2D scanners and dedicated devices that may focus on these specific formats, but neither is as prominently associated with passport reading compared to the common practice implemented at airports.
