What is a notable disadvantage of barcode readers?

One notable disadvantage of barcode readers is that they are not durable. Barcode readers, particularly handheld models, can be sensitive to physical damage, such as drops or exposure to liquids. This sensitivity can lead to malfunctions if the device is not handled carefully. In environments where durability is crucial, such as in warehouses or retail settings with high levels of activity, the lack of ruggedness can be a significant drawback.

On the other hand, while some options involve valid considerations, they may not hold the same weight as the durability issue. Maintenance costs can vary depending on the model, materials, and usage context; some readers can be relatively inexpensive to maintain. The scanning distance typically meets the needs of most applications; therefore, it is not a primary disadvantage. Furthermore, while many barcode readers do require a power supply, many models are designed with energy efficiency in mind and can operate for extended periods on battery power, minimizing concerns about constant power supply needs.
