Question 1

What is a QR code and how does it work?

Accepted Answer

A QR code is a square barcode that stores information like a website link, contact details, or payment info. When someone scans it with their phone camera, the code is read instantly and triggers an action — like opening a page or saving a number. It’s built to scan quickly and still work even if slightly scratched or printed imperfectly.

Question 2

Can I create QR codes for free?

Accepted Answer

Yes. You can generate QR codes for free and use them as much as you want. There’s no need to sign up, and you can download and use the QR code right away for personal or business purposes.

Question 3

What are common QR code mistakes?

Accepted Answer

The biggest issues are low colour contrast, making the code too small, or placing it on shiny or curved surfaces. These make scanning difficult. Always keep good contrast (dark code on light background), leave some white space around it, and test it on different phones before printing.

Question 4

How long are free QR codes valid? Do they expire?

Accepted Answer

QR codes created using Quicko Pro’s free QR code generator do not expire. These static QR codes remain valid as long as the linked content exists. You can safely use them on menus, posters, invoices, business cards, and other marketing materials without worrying about time limits.

Question 5

How do I scan a QR code?

Accepted Answer

Open your smartphone’s camera and point it at the QR code. A notification or link will pop up on your screen — tap it to continue. Most modern smartphones don’t need a separate app.

Question 6

Can I create QR codes on mobile devices?

Accepted Answer

Yes. You can easily create, preview, and download QR codes from a phone, tablet, or computer. No special app is required.

Question 7

Do QR codes need internet ?

Accepted Answer

Scanning a QR code doesn’t require internet, but what happens after scanning might. For example, opening a website or making a payment needs a connection, while saving contact details can work offline.

Question 8

How can I use a QR code builder for my business?

Accepted Answer

Businesses use QR codes to help customers take quick actions — like visiting a website, making a payment, viewing a menu, saving contact details, or finding a location. One small code can make it much easier for people to connect with your business instantly.
