Advice:How to Create a QR Code

QR codes (Quick Response codes) are two-dimensional barcodes that can store data such as URLs, contact details, payment links, or Wi-Fi credentials. When scanned with a smartphone or QR code reader, they instantly direct users to the linked content.

Originally invented in the 1990s for tracking automotive parts, QR codes are now used across industries—from restaurants and retail to education and healthcare. They offer a fast and contactless way to share or access information.

Why QR codes are important today

QR codes have become especially popular in recent years due to their convenience, touch-free use, and growing smartphone compatibility.

They help solve many modern problems:

Touchless transactions during and after the COVID-19 pandemic
Quick website access from print media
Easy information sharing like business cards, menus, or event invites
Faster app downloads via direct links
Improved marketing campaigns with embedded tracking URLs

Professionals, students, businesses, and content creators use QR codes to simplify interactions, boost accessibility, and create efficient communication points.

Laws or regulations around QR code usage

While QR codes themselves are not heavily regulated, their use in marketing and data sharing is often subject to broader laws. Here’s what to be aware of:

If your QR code links to a form collecting personal data, you must comply with data protection laws. Always inform users about data collection and obtain consent when needed.
