The evolution history of static scanning sorter can be roughly divided into the following stages:
1. Early stage (before 1990s)
Manual scanning: Early scanning sorting relied on manual operation, with staff using handheld scanners to read barcodes or QR codes.
Technical bottlenecks: Sorting is inefficient, prone to errors, and does not have automated functions.
2. Automation phase (1990s to early 2000s)
Introduction of automatic scanning equipment: With the popularity of bar code scanning technology, automated scanning systems have begun to be applied to logistics sorting.
Laser scanning technology: Laser scanners have become mainstream, with high scanning speed and accuracy, and are able to scan and identify the barcode of items in a static position.
3. Intelligent and integrated stage (mid-2000s to early 2010s)
Integrated system: Combining barcode scanning with automated equipment such as mechanical sorting systems and conveyor belts enables more efficient sorting operations.
Multi-dimensional scanning: Two-dimensional codes and RFID (radio frequency identification) technology are gradually applied, allowing the sorting system to process more complex item information, such as size, weight, production date, etc.
4. Modern Stage (2010s to present)
AI and big Data application: The introduction of artificial intelligence and big data analysis, through machine learning algorithms to optimize the sorting path and efficiency, improve the system's adaptive ability.

Using a variety of scanning technologies: combining barcode, two-dimensional code, RFID, laser scanning, visual identification and other technologies to improve the sorting accuracy and speed.
Unmanned operation: Some high-end sorting systems are unmanned, combined with automated transmission and robotic systems, improving overall operational efficiency and reducing labor costs.
Sum up
From the initial manual scanning to today's highly integrated automated and intelligent system, the static scanning machine has experienced an evolution process from simple bar code scanning to the use of diversified technologies. The development of technology has greatly improved the efficiency, accuracy and flexibility of sorting, and is widely used in express logistics, warehouse management and other fields.
