What is a QR Code?

A QR code (Quick Response code) is a type of barcode that can store information like website links, contact details, WiFi passwords, and plain text. When someone scans it with their phone camera, the information opens instantly — no typing needed.

QR codes were invented in Japan in 1994 and became globally popular during the COVID-19 pandemic when touchless menus and check-ins became necessary. Today over 6 billion QR codes are scanned every year worldwide.

6 Types of QR Codes You Can Create

1. URL QR Code

The most common type. Enter any website address and the QR code will open that page when scanned. Perfect for business cards, flyers, posters, and product packaging.

2. Text QR Code

Store any plain text — a message, instructions, a coupon code, or an address. When scanned, the text appears on the user’s screen without opening any app or browser.

3. Email QR Code

Scanning opens a new email with the address, subject, and message already filled in. Great for customer support contacts or newsletter signups on printed materials.

4. Phone QR Code

Scanning dials a phone number instantly. Useful for business cards and shop displays — customers just scan and call without typing your number.

5. WiFi QR Code

The most convenient type for businesses and homes. Customers scan the code and connect to your WiFi automatically — no password typing needed. Perfect for cafes, hotels, offices, and events.

6. vCard / Contact QR Code

Store your full contact card — name, phone, email, organization and website. When scanned, the user can save your contact in one tap. The modern replacement for the paper business card.

QR Code Size Guide

Rule of thumb: The scan distance should be about 10 times the size of the QR code. A 5cm QR code can be scanned from about 50cm away.

QR Code Color Tips

• Dark code, light background: Always use a dark color for the QR pattern and a light color for the background — never the opposite
• Contrast is essential: Low contrast QR codes fail to scan. Test before printing
• Avoid red on black: Some scanners struggle with red patterns
• Brand colors work: You can use your brand colors as long as there is enough contrast between the pattern and background
• Always test: Scan your QR code with multiple phones before printing it at scale

Where to Use QR Codes

• Business cards: Link to your portfolio, LinkedIn, or contact page
• Restaurant menus: Link to your online menu or ordering system
• Product packaging: Link to a tutorial video, warranty page, or reviews
• Social media bio: Link to multiple pages using a single QR code
• Shop window: Show your WiFi password or Instagram page
• Email signatures: Link to your portfolio or booking page
• Events: Share schedules, maps, or registration links
• Classroom / office: Share documents or presentation links instantly

Frequently Asked Questions

Are QR codes permanent?

Static QR codes like the ones generated on BuildDora are permanent — the data is stored inside the code itself and never expires. As long as the URL or information inside is valid, the code will always work.

Can I edit a QR code after creating it?

Static QR codes cannot be edited after creation. If you need to change the destination URL, you must generate a new QR code. For editable QR codes, you need a dynamic QR code service (usually paid).

Do QR codes work without internet?

The QR code itself works offline — scanning it is just reading data. However if the QR code contains a website link, you need internet to open that website. Text, phone, and WiFi QR codes work fully offline.

How many characters can a QR code store?

A QR code can store up to 4,296 alphanumeric characters. For best scanning reliability, keep your URLs short and use a URL shortener if needed.

Is the BuildDora QR generator really free?

Yes, 100% free. No watermark, no account, no limits. Generate as many QR codes as you need.
