Nobody Wants to Type a 60-Character URL
You have spent time building a great landing page, a Google Form, a portfolio, or a Wi-Fi login screen. Then you need to share it somewhere physical, a flyer, a business card, a presentation slide, a product label.
Suddenly you are staring at a URL that looks like this:
https://docs.google.com/forms/d/1Fk8xZ3mQpWv...
You cannot make that readable. You cannot expect anyone to type it out. And a tiny hyperlink text does nothing for print materials.
This is exactly the problem QR codes were built to solve, and in 2024 they are more practical than ever because virtually every smartphone camera scans them automatically.

Where QR Codes Actually Save You Time
QR codes are not just for restaurant menus. Here are situations where they genuinely remove friction:
Printed materials
- Business cards: link directly to your LinkedIn profile or portfolio site
- Flyers and posters: send people to an event registration page
- Product packaging: point customers to instructions, warranty registration, or support
In-person settings
- Conference booths: let visitors grab your vCard without typing anything
- Classroom handouts: link to supplementary reading or a video
- Shop counters: direct customers to a review page or loyalty program
Digital but non-clickable contexts
- Slide decks: attendees can scan a slide instead of scrambling to write something down
- Email signatures viewed on mobile: a QR code linking to your booking page can work better than a tiny hyperlink
- Video content: end screens with a QR code give viewers somewhere to go without leaving the platform
Wi-Fi sharing This one is underrated. Instead of reading out a complex Wi-Fi password to every guest or customer, you generate a Wi-Fi QR code once. They scan it, they are connected. That is it.

What Makes a QR Code Actually Usable
Not all QR codes are created equal. A few things matter:
Size and contrast
A QR code printed too small or with low colour contrast will fail to scan reliably. Dark content on a light background, printed at least 2 cm x 2 cm, is the baseline.
File format
If you are printing at large sizes, a PNG can go pixelated. SVG and PDF formats scale perfectly because they are vector-based. Always download the right format for the job:
- PNG for web use or small print sizes
- SVG or PDF for anything that needs to scale, banners, posters, large signage
Branding
A plain black-and-white QR code works, but on branded materials it can look like an afterthought. Being able to match the code colour to your brand palette makes a real difference in how polished the final product looks.
Content type
Different use cases need different QR code types:
- URL for any web link
- vCard for contact information
- Wi-Fi for network credentials
- Plain text for short messages or codes
Using the right type means the phone handles the action correctly, opening a contact save prompt instead of just showing raw text, for example.

A Simple Workflow for Making QR Codes That Work
- Know your destination first. If the URL might change, use a redirect URL you control so you can update the destination without reprinting.
- Choose the right content type. URL, Wi-Fi, vCard, or text depending on what you need.
- Customise for the context. Match brand colours if it is going on official materials. Keep it high contrast if it is going anywhere with uncertain print quality.
- Download in the right format. PNG for digital, SVG or PDF for print.
- Test before you distribute. Scan it yourself with two different devices before it goes on anything you cannot easily change.

The Bottom Line
QR codes are a small tool that removes a surprisingly large amount of friction. Anytime you need someone to get from the physical world to a digital destination, a QR code is cleaner than a printed URL, faster than typing, and more reliable than hoping people remember a domain name.
Set one up for your next flyer, business card, or presentation and see how much easier the handoff becomes.
