1D/2D scan

A 1D barcode scanner is designed to read traditional barcodes typically found on product packaging, inventory labels, and elsewhere. These barcodes consist of a single row of vertical lines with varying widths and spaces that represent numerical or alphanumeric data. 1D barcode scanners are effective for fast and reliable reading of these types of barcodes, and they are often more cost-effective than 2D scanners.

Compatibility: Ensure that the barcode scanner is compatible with the types of barcodes you need to work with, such as EAN-13, UPC-A, Code 39, etc.

Scanning speed: Choose a scanner that can handle the expected number of barcodes per minute to maintain efficiency.

Durability: If the scanner will be used in an industrial or warehouse environment, it needs to be robust and able to withstand shocks and vibrations. See our rugged barcode scanners here.

Connectivity options: Pay attention to whether the scanner has the necessary connectivity options (e.g., USB, Bluetooth) to integrate with your existing systems.

A 2D barcode scanner is capable of reading both traditional 1D barcodes and more complex 2D barcodes. These 2D barcodes can contain a larger amount of data and can be found on a wider range of products and packaging. In addition to reading barcodes, 2D scanners can also read QR codes, data matrix codes, and other types of 2D codes.

Functionality: Make sure the scanner supports the types of barcodes and 2D codes you need to work with.

Additional features: Some 2D scanners may offer extra features like image capture, documenting damage, and associating information with scanned codes.

Software integration: Check if the scanner is compatible with your existing software and systems to ensure seamless integration.

Reading speed: Although 2D scanners are typically slower than 1D scanners, choose a model with adequate reading speed for your needs.

The primary difference between a 1D and 2D barcode scanner lies in their ability to read and decode different types of barcodes:

1D barcode scanner: A 1D barcode scanner is specifically designed to read linear or one-dimensional barcodes, which consist of vertical lines of varying widths and spaces. 1D barcodes are typically used for product identification, inventory tracking, and retail pricing management.

Examples of 1D barcodes: EAN-13 (European Article Number), UPC (Universal Product Code), and Code 39.

2D barcode scanner: A 2D barcode scanner has the capability to read both linear (1D) and two-dimensional barcodes. These barcodes can contain much more information than 1D barcodes due to their two-dimensional nature. They can include text, numeric data, web addresses, images, and even binary data.

Examples of 2D barcodes: QR codes (Quick Response), DataMatrix, and PDF417.

Depending on the company’s needs and usage scenarios, one should choose the type of barcode scanner that best fits the specific requirements for accuracy, speed, and mobility. At Delfi Technologies, we offer a wide range of 1D and 2D barcode scanners, including wired scanners, presentation scanners, and wireless scanners.
