Technically, a QR code is just a type of barcode
There are two types of barcodes—one-dimensional and two-dimensional.
And, two-dimensional barcodes are also divided into various types… with QR code being one of them.
The one-dimensional barcode, or the Linear barcode, was first introduced to the manufacturing industry before the 2D versions.
But because of its very limited storage capacity (approximately 85 characters), product inventory and management companies demand another barcode that can store more than just what the 1D barcode could offer.
So, the two-dimensional barcodes were equipped with a larger storage capacity, a four-tiered error correction feature, and a patterned appearance.
And one of them is QR code.
A QR code can store over 4,000 characters compared to the original barcode.
You can embed texts, numbers, and URLs using a QR code. This makes it an ideal tool for any modern digital campaign.
The 2D barcodes are also a very versatile tool since it can be deployed on physical and digital surfaces, is scannable using even a smartphone, and works very well with any industry and agency.
And here’s the best part—you can edit the embedded information and track the data scans of the QR code.
These are two things that aren’t available to all one-dimensional barcodes.
