There are a wide variety of handheld computers to address a wide range of application needs. To choose the most suitable solution, you need to understand the barcode reading requirements first. In this article, we'll learn how to choose the right barcode reader and quickly find the best solution!
When choosing a barcode reader, you need to consider the specific barcode reading application, and the following factors must be considered when choosing a barcode reader:
symbol
Inventory or tracking applications can now require only a few thousand bytes of data, making 1D barcodes seem like the most logical choice. However, data requirements can grow with the size and complexity of operations. It is expected that future applications will benefit from QR codes or the ability to read damaged barcodes. Buying better technology equipment can reduce the chances of future equipment upgrades.
Read rate
The read rate is the number of barcodes successfully read divided by the total number of barcodes invested, usually expressed as a percentage, with closer to 100% the better. Machine-readable codes can be damaged when a product is handled manually or by a machine. To ensure supply chain accuracy, it's important to ensure that barcode readers can read noisy codes.
Barcode reading environment
For applications that require reading cartons of all sizes moving at high speeds on conveyors, fixed-mount barcode readers are the best choice. Fixed barcode readers are capable of automating, hands-free scanning of codes from the mounting position.
Handheld barcode readers are ideal for dock workers who load incoming materials or outbound products for final inventory checks. If you're a courier or technician working in the field, a mobile barcode reader with built-in barcode reading capability allows the operator to operate handheld and quickly scan packages or check equipment specifications. These barcode readers can be designed for specific applications or smartphones with durable mobile terminal housings.
correspondence
Once a workpiece or product is marked and the code is read, the data is stored and used in a network of factories or distribution centers. Image-based barcode readers offer a full range of industrial communication protocols, including Ethernet, USB, RS-232, discrete I/O, ETHERNET/IP, PROFINET, and Modbus TCP/IP. This is not only important for reading and sending product tracking information, but also for saving archived images that have not been read or missed.
cost
The cost of the latest image-based barcode readers is comparable to that of laser scanners. The new microprocessor and CMOS digital sensor chips also mean that image-based systems are almost as fast as the fastest laser scanners. It combines the traditional advantages of image-based barcode readers—no moving parts, longer life than laser readers; Ability to read QR codes and damaged codes and all-around codes; Ability to save images for querying and tracking.
If a facility increases its read rate from 99% to 99.9% with image-based barcode readers, it can save significant labor costs, as well as impact on customer relationships and corporate branding. If it is an industrial application, avoid choosing a consumer-grade solution and choose a stable solution that is designed to minimize failure.
