Complete Guide to 1D barcodes and 2D barcodes

As we know barcode is a method of representing data in a visual, machine-readable form. Mainly there are two kinds of barcode, 1D barcodes or Linear barcode and 2D barcodes. 1D barcodes are an older form of technology and one that is more commonly used and mostly found on consumer goods while 2D barcodes utilizes patterns such as squares, hexagons and dots to encode information.

Difference Between 1D barcodes and 2D barcodes

1D or Linear Barcodes: 1D barcodes are commonly found on consumer goods, and use a series of variable-width lines and spaces to encode data. They hold immediately a few dozen characters, and usually get physically longer as more data is added. Because of this, users normally limit their barcodes to 8-15 characters. Linear codes also depend on database connectivity to be important. When the scanner peruses the numbers in the code, they must be connected back to item information, estimating information, or other data. This barcode systems are a need for large retailers, and can help increase inventory accuracy and save time. Some examples of scanners for 1D barcodes are the Microscan QX 830 series and QX-870 series

2D Barcodes: A 2D barcode utilizes patterns such as squares, hexagons and dots for encoding information. A 2D barcode contains more information than just mathematical information. They can contain names, addresses, phone numbers, images, website URLs and further. Additionally, 2D barcodes are sturdier and can be read even if a part is damaged. These barcodes can also encode i website addresses, sound, and other varieties of binary data. Because of this, they can be scanned and read regardless of whether the scanner is connected to a database or not. 2D barcode scanners can read from over 3 feet away and are accessible in the common “gun” style, as well as cordless, countertop, and mounted styles. Some 2D barcode scanners are also attuned with 1D barcodes, giving the user more flexibility in how they are used.

While there is a difference between 1D and 2D barcode scanning, both types are useful, economical methods of encoding data and tracking items. The kind of barcode (or combination of barcodes) you select will depend on the definite requirements of your application, including the type and amount of data you need to encode, the size of the asset, and how and where the code will be scanned.
