Barcode scanner for retail, logistics, and warehouse – choose the most suitable model at Rolling!

Barcode scanners are devices used to read and interpret barcodes (usually printed on product packaging) to retrieve product information. A barcode is a visual representation containing data that can be deciphered using light or laser beams.

Barcode scanners are widely used across various industries, from retail to logistics and healthcare. The scanner extracts the information embedded in the barcode’s lines and encodes it as bars (stripes) or squares (QR codes), then converts this information into a format that computers can process. Today, different barcode scanners are available to suit various needs and environments.

Main types of barcode scanners:

1. Laser barcode scanner: A laser scanner is the most common type and operates using laser beams to read barcodes. These scanners are highly accurate and fast, but they require a direct line of sight to the barcode. Laser scanners are ideal for retail barcode scanning, where speed and precision are crucial.
2. Imager (image-based) scanners: These scanners use digital camera technology to "capture" the barcode and process the image to extract the data. They can scan barcodes from any angle and recognize two-dimensional codes, such as QR codes. A QR code scanner efficiently processes various codes.
3. Wireless barcode scanner: A Bluetooth barcode scanner or a wireless barcode scanner is perfect for working without restrictions, allowing employees to move freely around warehouses or stores. This is highly convenient when greater mobility is required, such as with a portable barcode scanner.
4. Portable barcode scanner: These scanners are small, lightweight, and easy to use, making them ideal for warehouse or logistics applications where mobility and quick access to product information are essential.
5. Retail barcode scanner: A scanner for retail is designed for high-volume operations, such as cashier work, enabling quick barcode scanning at the checkout. These scanners often include additional features, such as QR code support or integration with other system solutions.

How do barcode scanners work?

A barcode scanner is placed over a barcode and emits light (a laser beam or LED light), which reflects off the barcode surface and returns to the scanner. The barcode lines reflect light differently based on their width and darkness, allowing the scanner to decode the information.

For example, a 1D barcode (linear barcode) is deciphered based on the thickness of the bars and the spacing between them. 2D codes (such as QR codes) are decoded based on patterns of squares and their relationships.

Advantages of barcode scanners:

• Speed and efficiency: Barcode scanners allow for the rapid retrieval and processing of information, significantly speeding up work processes and reducing the chance of errors. This is essential for warehouse and retail barcode scanners.
• High accuracy: Barcode scanners are highly precise, eliminating human errors that can occur when entering data manually.
• Versatility: Different types of scanners are available, from simple 1D to more complex 2D scanners, and they are used in various industries. For example, a retail barcode scanner is ideal for stores, while a logistics scanner helps track product movement more accurately.

Where are barcode scanners used?

• Retail barcode scanners: A store barcode scanner is used for scanning products at checkout or within inventory management systems, simplifying pricing, stock tracking, and transaction processing.
• Logistics barcode scanners: A logistics scanner and warehouse scanner are used in shipping, storage, and tracking, enabling quick and efficient order processing.
• Healthcare barcode scanners: Scanners are used for medication identification, patient record registration, and tracking medical equipment in hospital inventory systems.

How to use a barcode scanner?

To use a barcode scanner, follow these steps:

1. Connect the scanner: Attach it to a computer or POS system (via USB cable or Bluetooth).
2. Open the required software: For example, Excel, a POS system, or another application where data entry is needed.
3. Scan the barcode: Point the scanner at the barcode and press the button to read it.
4. Data is entered automatically: The scanner will input the data directly into the selected software.

Simply start scanning and ensure the scanner is properly connected to the device.

How to Connect a Barcode Scanner to a Computer?

Connecting a barcode scanner to a computer is simple. Depending on the type of scanner, here are the two main methods:

1. Wired Barcode Scanner (USB Connection):
• Connect the USB Cable: Insert the scanner's USB cable into the computer's USB port.
• Scanner Recognition: Most scanners are recognized as keyboard devices, so no additional software or drivers are required.
• Test: Open a program like Excel or a text editor and scan a barcode. The data will appear as text.

2. Wireless Barcode Scanner (Bluetooth Connection):
• Enable Bluetooth: Turn on Bluetooth on both the computer and the scanner.
• Pair the Scanner with the Computer: Go to the computer's Bluetooth settings, search for the scanner, and pair them.
• Test: Once connected, scan a barcode, and the data will appear in the selected program.

How to Scan QR Codes with a Barcode Scanner?

To scan QR codes with a barcode scanner:

1. Check if the scanner supports 2D codes (QR code scanning requires 2D support).
2. Connect the scanner to a computer or device (via USB or Bluetooth).
3. Point the scanner at the QR code and press the button.
4. The result will appear on the screen (e.g., URL or text).

If the scanner supports 2D codes, it will read the QR code and automatically input the data.

How to Choose the Best Barcode Scanner?

When choosing the best barcode scanner, consider these factors:

1. Type: Choose between a 1D scanner (traditional barcodes) or a 2D scanner (QR codes, 2D barcodes).
2. Connectivity: Wireless (more convenient for mobility) or wired (cheaper, stable connection).
3. Environment: If the scanner will be used in harsh conditions, choose a durable model with IP protection.
4. Scanning Distance: Select a scanner with the necessary reading range for your work.

What is the Best Barcode Scanner for a Retail Store?

The best barcode scanner for a retail store depends on your needs:

1. Wireless vs. Wired: Wireless scanners offer more mobility, while wired scanners are cheaper and more stable.
2. 1D vs. 2D: 1D scanners are suitable for traditional barcodes, while 2D scanners are necessary for QR codes.
3. Durability: Choose a durable scanner with IP protection.
4. Speed: Look for a fast and accurate scanner.

Can a Barcode Scanner Read Damaged or Torn Barcodes?

Barcode scanners can read damaged or torn barcodes, but this depends on the scanner type and the extent of the damage.

Consider the following:
1. High Quality and Accuracy: Modern scanners (especially 2D scanners) have enhanced capabilities to read partially damaged or torn barcodes.
2. Damage Level: If a barcode is severely damaged (e.g., a large portion is missing or torn), it may cause problems, and the scanner may not be able to read it.
3. Use High-Quality Scanners: A good choice would be a scanner with high accuracy and excellent error correction, such as Zebra or Honeywell models.

What to Do If a Barcode Scanner Does Not Scan a Barcode?

If a barcode scanner does not scan a barcode, try these solutions:

1. Check the barcode – ensure it is not damaged or improperly oriented.
2. Check the scanner settings – make sure it is set to the correct barcode type.
3. Check the connection – ensure the scanner is properly connected.
4. Clean the scanner – wipe the scanner lens.
5. Restart the scanner – turn it off and on again.

What to Do If a Barcode Scanner Does Not Connect to a Computer or POS System?

If a barcode scanner does not connect to a computer or POS system:

1. Check the connection: Ensure the USB cable or Bluetooth is correctly connected.
2. Check the settings: Install necessary drivers and ensure compatibility.
3. Restart the devices: Restart the computer/POS and the scanner.
4. Check the USB ports: Try connecting the scanner to a different USB port.
5. Test with another device: Verify if the scanner works with another device.

If the issue persists, the scanner may be faulty.
