Code scanner

Types of code scanners

A code scanner is a type of scanner that detects and decodes barcodes and QR codes to obtain their numeric and alphanumeric values. Barcode scanners and QR code scanners are widely used in the retail, manufacturing, healthcare, and transportation industries. They improve accuracy and speed in various tasks, such as inventory management and product tracking.

While the global market for barcode scanners is expected to grow from USD 8.5 billion in 2023 to USD 15.7 billion by 2031, barcode scanners can be segmented according to their categories:

• Laser bar code scanners: Laser barcode scanners use a laser beam and a photodetector to read barcodes accurately, even in difficult conditions such as low light or high glare. They offer excellent precision and range for scanning barcodes that are damaged, poorly printed, or very small.
• CCD (Charge-Coupled Device) scanners: These handheld barcode scanners have multiple sensors on the head that take many pictures of the barcode. The scanner processes the images and converts them into digital data that can be sent to a computer. CCD scanners are reliable and durable, with no moving parts. However, they may have difficulty reading barcodes with low contrast or very high glare.
• Imaging scanners: These barcode scanners use a camera-like device to capture an image of the barcode and decode it. The imaging technology allows them to read barcodes in various conditions and orientations, including damaged or distorted ones. They can also read 2D codes, such as QR codes, providing more information than traditional barcodes.
• Bluetooth barcode scanner: These types of machines work wirelessly via Bluetooth. They can connect to smartphones, tablets, or other devices to transmit scanned data in real time. Bluetooth barcode scanners are flexible and convenient, allowing users to scan barcodes from a distance without cables.
• Handheld scanners allow users to point and shoot the scanner at the barcode for accurate scanning. Fixed mount scanners are used in production lines or checkout counters where the barcode passes under a stationary scanner that reads it. Omnidirectional scanners can scan barcodes in any orientation, making them suitable for applications where barcodes are not properly aligned.

Function and features of code scanner

Apart from scanning codes, well-known functions that may be expected of a scanner include:

• Computer and application integration: This integration may be achieved through wired or wireless connection methods. It comprises options for real-time data transmission to applications or storage devices, as well as data processing and further analysis.
• Data quality: This means that the scanned data should be accurate and have high integrity, implying that the codes must be identified correctly without mistakes. The code scanner must also be able to minimize data entry errors during dynamic code scanning.
• Scanning speed and performance: This refers to the rapid response of the scanner while capturing codes, especially in high-volume environments. It also means that there are no lags or delays in code processing.
• User experience and ergonomics: Features that improve scanning comfort and simplicity over extended periods are included in this. They may entail straightforward use, possible one-handed operation, as well as the capabilities of targeting and focusing on codes quickly.

Usage scenario of code scanners

Code scanners have a broad range of applications, making them a versatile tool for collecting and managing data efficiently. Here are the major use cases of code scanners:

• Retail and Inventory Management

  In retail stores, barcode code scanners are used at checkout counters to scan barcodes on products for fast and accurate transaction processing. These scanners are also used for stock-taking, receiving shipments and verifying product labels. Businesses can maintain accuracy and efficiency in inventory management by using barcode scanners to monitor stock levels and track product movement.

• Logistics and Transport

  Businesses in the logistics and transport industries rely on code scanners to perform tasks such as tracking shipments, verifying packing lists and ensuring compliance with industry standards. Package labels with barcodes or QR codes are scanned to validate information and monitor the movement of packages through the supply chain. This improves efficiency and reduces errors in the transport process.

• Manufacturing and Production

  Manufacturers use barcode scanners to track production processes, manage assets and ensure quality control. They can monitor product status and location by scanning codes on labels or displays. This allows them to identify any issues promptly and implement corrective actions to maintain product quality.

• Healthcare and Pharmaceuticals

  Code scanners play a vital role in patient identification, medication management and inventory control in hospitals and healthcare facilities. Medical professionals can accurately validate patient information and medication instructions by scanning barcodes or QR codes on wristbands, prescriptions and medication labels.

• Event Management and Access Control

  Code scanners are widely used in stadiums, concert halls, and amusement parks for event management and access control. Attendees are checked in quickly and efficiently by scanning the barcodes or QR codes on tickets to reduce waiting time and improve security.

• Mobile Applications

  Mobile applications such as payment, shopping and travel apps use smartphone cameras as code scanners to capture barcodes or QR codes for various purposes, including mobile payments, discount coupons and boarding passes.

• Government and Public Sector

  Code scanners are used in various government agencies and public sector organizations for tasks such as document management, asset tracking and citizen services. They can improve efficiency and accuracy in these processes by digitizing data and automating information retrieval.

How to Choose a Code Scanner

When choosing the code scanner that fits the user's needs, it is important to consider some situations and pay attention to some factors.

These factors include:

• Scanning speed: When choosing a scanning device, it is important to check its scanning speed. Select vendors that provide information on the scanning rate of their devices. Consider businesses that require high-speed scanning, like airline check-ins or warehouse operations. The portable code scanner is better for applications that don't need very high-speed scanning but require flexibility and mobility.
• Decoding Performance: This refers to the ability of a scanner to decode various types and qualities of codes. When choosing a scanner, it's important to select one with a good decoding performance for various codes, especially in different conditions or poor-quality printing.
• Connectivity options: When choosing a scanner, the connectivity options should be considered. These include Bluetooth, WiFi, USB, and wired connections. Portable models frequently make use of Bluetooth and WiFi connectivity. To transfer data between the scanner and other devices, choose the connection possibilities that correspond to the scanter.
• Ergonomics: When making decisions, the scanner's design must be taken into account. For pleasant use, particularly during extended scanning sessions, choose a scanner with an ergonomic design. User fatigue and errors in the scanning process could be reduced by using an uncomfortable scanner.
• Durability: When selecting a scanner, durability features are important to take into account. To guarantee that the code can withstand drops and difficult circumstances, choose scanners manufactured with robust materials. For outdoor or industrial applications, consider the scanner's IP rating, which denotes protection against dust and water.
• Power options: Decide on the power alternatives that would be most effective for the scanning process. Examine whether the cordless or wired option is better for users. Cordless scanners require recharging or battery changes, so consider the runtime and battery type. Wired scanners, on the other hand, need a reliable power source to function.
• Operating system: Different scanners run different operating systems. These may include Windows, Android, or a custom OS. The OS affects how the scanner works and what features it has. Consider compatibility with other devices and systems when choosing an OS.
