Types of COM Barcode Scanners

A COM barcode scanner is also known as a common object model barcode scanner. It is an automatic scanning and data gathering tool that helps in the fast collection of computer-readable bar code data in various industries.

Coders create barcodes using well-known libraries, and scanners read the barcodes. The barcodes can be on labels printed on products or displayed on screens. When scanned with a scanner, the information is sent to a computer system for processing.

This scanner comes in different types, depending on how people use them. They include;

• Handheld COM Barcode Scanner: This is the most popular type of barcode scanner. It is small, light, and portable. Users can easily handle and move them around to scan barcodes on products. Handheld COM scanners can be corded or cordless. Corded models get power and data connectivity from connecting the scanner's cable to the COM port of a PC. On the other hand, cordless handheld scanners use wireless connectivity like Bluetooth or Wi-Fi to connect with computers.
• Fixed Mount COM Barcode Scanner: A fixed mount barcode scanner is a type of barcode scanner that is mounted at a fixed position to scan barcodes on products as they pass through. It is commonly found in factories, assembly lines, or areas with high-speed product movement. The scanners provide accurate and high-speed scanning, hence increasing productivity in environments with a large volume of goods.
• OEM COM Barcode Scanners: These types of barcode scanners are manufactured to be integrated into other products or systems. They are mostly found embedded in handheld devices, kiosks, and point of sale terminals.

Functions and features

• Scanning Technology:

  Most handheld barcode scanners use either laser or linear imaging (CCD) technology to scan barcodes. Laser scanners are fast and can scan long-range barcodes in a wide variety of lighting conditions. Linear imaging scanners work well in normal lighting and are more affordable.

• Connectivity:

  Wired barcode scanners connect via USB or PS/2 connections. USB scanners are the latest standard and plug directly into a computer. PS/2 scanners are older and connect to the same port used by computer keyboards. Wireless scanners provide cable-free convenience. Bluetooth and Wi-Fi are popular wireless technologies. Bluetooth connects to mobile devices and POS systems, while Wi-Fi scans barcodes and transmits data to the system over the local network.

• Scanning Speed:

  Scanning speed is important for high-volume applications. Some scanners can take only a fraction of a second to read a barcode, while others may be slower. Scanners with good illumination capabilities can read codes quickly, even in low-light conditions.

• Durability:

  A durable scanner can withstand typical drops, spills, and other rigors of daily use. Look for scanners rated IP65 or higher for water and dust resistance. Consider models with drop-resistant housing made from rubber or metal. Some barcode scanners have protective covers for the scanning window to prevent scratches.

• Battery Life:

  For wireless scanners, a long-lasting battery minimizes downtime. Choose scanners that last 8-12 hours on a single charge. Models with lithium-ion batteries offer excellent battery life and only require minimal maintenace.

• Form Factor:

  Choose the right size and shape to ensure the scanner is easy to grip and use comfortably. Handheld scanners are good for portable tasks, while fixed-mount scanners are best for point-of-sale stations.

• Scan Angle:

  Able to read barcodes at various angles. This capability is essential for applications that involve scanning damaged or poorly printed codes.

• Decode Capability:

  Refers to its ability to read different types of barcodes. Some scanners can only decode 1D codes, while others can decode 2D codes such as QR codes, Data Matrix, and PDF417.

Scenarios

Wucom barcode scanners are useful in many industries for fast and accurate data collection. Here are some applications of barcode scanners in different areas.

Warehouse - Barcode scanners simplify inventory tasks in warehouses. Scanning barcodes quickly updates inventory levels during stock counting, receiving, and shipment. Also, using barcode scans to verify each step reduces errors in order fulfillment. This helps warehouses work faster and improves accuracy.

Retail - In retail businesses, barcode scanners speed up the checkout process by reducing human errors when inputting product codes. During purchases, customers can get more attention as cashiers work faster. Also, barcode scanning helps with inventory management by making tasks like stock taking and restocking simple.

Library - Barcode scanning makes tracking and managing books effortless. Each book has a barcode that a scanner can read to check it in or out. This process reduces mistakes and saves time in book lending and returns. Also, barcode scanners help with periodic stock audits by making it easy to verify all the books in the library.

Manufacturing - Barcode scanners play an essential role in keeping the production process efficient. They enable manufacturers to track parts, items, and products as they move through different stages. Scanning barcodes on materials at the beginning alerts the system to any mistakes in the bill of materials (BOM). Then, operators can prevent issues that can cause delays in production.

Food Industry - Barcode scanners are an important tool for businesses that handle perishable food. Each item can have a barcode with details such as the type of food, packing date, and expiry date. Scanning the barcode allows staff to check all relevant information quickly. This reduces the time food inspectors spend on examinations.

Healthcare - Barcode scanners improve patient safety in hospitals. By scanning patient wristbands and medications, nurses and doctors can double-check orders before giving treatment. This reduces the risk of mistakes caused by misidentification.

How to Choose com Barcode Scanner

Customers should consider various factors before selecting a barcode scanner to ensure they choose the scanner that is right for their needs and is suitable for their business. The factors to consider include;

• Scanning technology: As seen before, there are different ways of scanning and decoding barcodes. Laser scanners scan barcodes using a laser beam and a lens detector, while 2D area imagers use a camera-like technology to capture the entire barcode in high resolution. CCD, on the other hand, uses an array of light sensors to read barcodes. Each technology has its pros and cons. The laser scanner has an advantage over the others when it comes to scanning barcodes that have a small size or dense data. CCD can read reflective barcodes, which is usually a challenge for laser scanners. For barcode scanners with imaging technology, they are usually faster when it comes to scanning 2D codes and handling damaged or imperfect codes.
• Connectivity: Barcode scanners can be connected to a computer via cable or wirelessly. Wired scanners provide reliable transmission but offer limited mobility, while wireless scanners offer flexibility and freedom of movement. Wireless scanners are best used in dynamic environments.
• Range: Barcodes come with different models that can scan data at various distances depending on their type. Almost all barcode models can read data at close contact, while the general model can read up to 6 inches barcode printed on paper. The laser barcode scanner can read barcodes from several inches to many feet, especially those with zoom or high-power optics. The rugged barcode scanner can scan barcodes from close contact to several feet, especially in cases where moisture, pressure, and high temperature exist.
• Environment: The barcode scanner's operating environment is a crucial factor to consider. Barcode scanners used in retail stores operate in normal room temperature, while those used in warehouses operate in high humidity and temperature. Some barcode scanners are designed to withstand harsh environments.
• Power source: Barcode scanners use different power sources to power their operations. Some scan cords supply power to the scanner and transmit data, while corded models rely on mains power. Cordless barcode scanners use rechargeable batteries that are built-in.

Q & A
