What Is a Data Collector?
A data collector is a compact electronic device that reads and processes barcodes, performing tasks such as data storage and verification.
Commonly used in warehouse inventory management, the KOAMTAC Data Collector (KDC), developed in the early 2000s by KOAMTAC, a U.S.-based company, is considered a pioneering device in this field. Data collectors, similar to barcode readers and handheld terminals with scanning capabilities, differ in their smaller size, lightweight design, and cordless portability, allowing for easy carrying and operation in various work environments.
Other types of data collectors are used in civil engineering and construction for survey data storage and analysis, but these serve different functions and purposes than those used in inventory management.
Uses of Data Collectors
Data collectors are integral to efficient inventory management in warehouses, enabling quick barcode scanning of products and packages. Transferring this data to a computer facilitates analysis and inventory control. They are also used in manufacturing plants and medical settings for verifying parts and drugs against pre-registered barcodes, reducing the risk of errors in part selection or drug administration.
Principles of Data Collectors
Data collectors comprise a barcode scanner, memory, a processing unit for data operations, a small LCD display, operational keys, and often a speaker for operational feedback. Some models include a vibration feature for error alerts. They are powered by batteries and offer data transmission options like USB and Bluetooth, with Bluetooth-enabled models capable of real-time data transmission within a communication range.
Regarding size, data collectors vary from smaller models measuring 35mm x 62mm x 15mm and weighing 34g (battery included) to larger models measuring 125mm x 46mm x 31mm and weighing 115g. They are designed to be more compact and lightweight than handheld terminals, focusing on portability and specific functionalities like barcode scanning and data storage rather than complex tasks.
How to Choose a Data Collector
When selecting a data collector, consider its core functionalities: barcode reading and storage, data transmission to PCs, and barcode verification. Storage capacity typically suffices for tens of thousands of entries. For real-time data transfer, models with wireless communication like Bluetooth are recommended.
Battery life, which can vary from a few hours to over twelve hours, should align with the task duration. Additional features like display messages, sound notifications, and vibration alerts for errors enhance usability. Options for hands-free operation, such as attaching to gloves or mounting on fixed stands, cater to specific needs.
Consider specifications like operating environment temperature, impact resistance, barcode types, reading distance, and speed to ensure the data collector meets your requirements.
