Types of Barcode Scanners: Choosing the Right Technology for Your Needs
Barcode technology has been an integral part of various industries for decades. From retail to logistics, organizations rely on barcodes to streamline and optimize their processes. One crucial component of this technology is the barcode scanner, which is responsible for capturing and decoding barcode information. In this article, we will explore the different types of barcode scanners currently available, including their advantages, disadvantages, and ideal application scenarios.

1. Laser-Based Barcode Scanners
Laser-based barcode scanners have been in use for several decades, and they are still widely employed in industrial applications such as warehousing. These scanners use a moving laser beam to scan and decode barcodes. While they have a reputation for being fragile due to their numerous moving parts, they have benefited from extensive improvements over the years. They are renowned for their speed and accuracy, making them suitable for high-volume retail environments.
Laser scanners are particularly useful in environments with narrow barcodes or in situations where the barcode is not perfectly aligned. However, they are often more expensive than other types of scanners and may require regular maintenance due to the presence of numerous moving parts.
2. 2D Imagers for Barcodes
2D imaging scanners represent a significant advancement over traditional barcode readers. These scanners use a camera and image processing techniques to decode barcodes, including QR codes. The most common type of 2D imager is the smart phone, which has become a popular barcode reader among individuals and businesses alike.
Modern 3D image scanners with laser diodes can capture and decode any image, making them highly versatile. They are also capable of encoding functions and can even capture RFID GEN 2 labels and PDF 417 barcodes. These scanners are ideal for applications requiring high-speed data capture, such as EDI (Electronic Data Interchange) functions. Incorrect inputs can be voided, which is a critical feature in industries where accuracy is paramount.
3. Business Barcode Scanner Types
Pen Type Readers
Pen type readers, also known as barcode wands, are the most basic type of barcode scanner. These devices work by passing a beam of light over the barcode and interpreting the reflected light to determine the barcode's contents. They are simple to use but are not as versatile as other types of scanners. Pen type readers are best suited for low-volume applications where the barcode must be precisely aligned.
Laser Barcode Scanners
Laser barcode scanners are the most popular type of barcode scanner and are widely used in retail environments. They are more advanced than pen type readers and offer higher accuracy and faster scanning speeds. They are ideal for high-volume applications where speed and reliability are crucial. Despite their popularity, laser scanners can be more expensive and require more maintenance compared to other types.
CCD Barcode Scanners
CCD (Charge Coupled Device) barcode scanners are a type of 2D imager that uses a camera to capture an image of the barcode. CCD scanners are known for their high resolution and ability to read barcodes even when they are slightly dirty or damaged. They are suitable for applications requiring high-resolution scanning, such as in the manufacturing industry.
Imager Barcode Scanners
Imager barcode scanners, also known as camera-based barcode scanners, are another type of 2D imager. They use a digital camera to capture an image of the barcode and then decode it using advanced image processing algorithms. Imager scanners are highly versatile and can read a wide range of barcodes, including QR codes and Data Matrix codes. They are ideal for environments where multiple barcode types need to be read quickly and efficiently.
Why Not Try RFID Technology?
While barcode technology is widely used, RFID (Radio-Frequency Identification) technology offers unique advantages for certain applications. Barcode and RFID technologies serve different purposes and can be complementary in many scenarios.
Barcodes use a scanner with a beam of light to detect the black and white lines of a barcode. The scanner decodes the lines and turns them into text, which is then sent to a computer database for later analysis. For accurate reading and transmission, the scanner must capture every line of the code.
RFID technology, on the other hand, uses radio waves to transmit data from RFID tags, which are typically small chips embedded in sensors. Each sensor is unique, and RFID readers can scan several tags at once, making them ideal for scenarios where multiple items need to be tracked simultaneously. RFID can also be used for access control, inventory management, and asset tracking, among other uses.
