Simpe online QR barcode generator

Short introduction

Two-dimensional, (or 2D) barcodes encode data on both the horizontal and vertical axes. They are similar to a linear 1D barcode, but can represent more data per unit area. 2D barcodes include some newer barcode types, such as QR codes, PDF417 and Data Matrix.

Another key advantage of 2D barcodes is their error-protection formulas. These codes are designed to keep data intact and scannable - even after being ripped, scratched or damaged. This feature makes 2D barcodes uniquely suited to more intense, fast-paced scanning applications.

Barcode scanning software running on smart devices can read either 1D or 2D codes - or be easily upgraded to do so. However, older dedicated scanning devices (such as laser scanners) can often only read 1D codes. Not having the right barcode scanning hardware or software to scan the code your industry uses is a common barcode scanning challenge.

QR Code

QR codes are most often used in tracking and marketing initiatives, such as advertisements, magazines and business cards. They are flexible in size, offer a high fault tolerance and have fast readability, though they can't be read with a laser scanner. QR codes support four different modes of data: numeric, alphanumeric, byte/binary, and even Kanji. They are public domain and free to use.
