A handheld terminal is a portable data-processing device equipped with an operating system (such as Android or WinCE), memory, CPU, graphics card, display screen, keyboard, data-transfer capabilities, and a rechargeable battery. These devices are broadly categorized into industrial-grade and consumer-grade handheld terminals. Industrial-grade handheld terminals outperform their consumer-grade counterparts in terms of performance, stability, and battery durability, making them suitable for demanding environments.

With the advancement of Internet of Things (IoT) technology, handheld terminals have become essential tools for data collection and information processing. They are widely utilized across various industries, including fashion, retail, logistics, transportation, healthcare, manufacturing, energy, finance, and government utilities. In each sector, handheld terminals play a critical role in streamlining operations, enhancing efficiency, and supporting decision-making processes.
