Generate Custom QR Codes in Seconds: The Ultimate Guide

QR codes, short for “quick response” codes, are a type of barcode that can be read by smartphones and dedicated QR scanners. Unlike a standard barcode, QR codes can store much more data, including text, URLs, contact information, calendar events, and more.

QR codes were invented in 1994 by the Japanese company Denso Wave. The technology was originally designed to track vehicle parts in manufacturing plants. However, it wasn’t until the rise of smartphones with built-in cameras that QR codes became widely used by consumers.

So how do QR codes work exactly? QR codes are made up of a series of black and white squares arranged in a square grid. This pattern of squares encodes data using something called Reed-Solomon error correction. This allows the code to still be read correctly even if it is partially damaged or dirty.

When you scan a QR code with your smartphone’s camera, it uses the patterns in the code to detect and extract the encoded data. This data might be a website URL, contact info, or any other type of information. The QR code reader on your phone interprets this data and performs the intended action, like opening a website or adding a contact.

Today, QR codes are commonly used to make offline content instantly accessible by smartphone. Businesses place QR codes on advertisements, product packaging, receipts, and signs to allow customers to quickly view digital content by scanning the code. QR codes can also automate tasks like signing up for a mailing list, following a social media account, or downloading an app. Overall, the technology provides a seamless bridge between the physical and digital world.
