QR Codes Went From Dead to Everywhere (Here's How to Actually Use Them)

QR codes have been declared dead more times than a soap opera character. Tech journalists wrote their obituary in 2013, 2015, 2017, and 2019. Then a pandemic happened and suddenly every restaurant menu was a QR code.

Plot twist: they’re actually useful now. Here’s how to use them without being annoying.

Why QR Codes Work Now (When They Didn’t Before)

Two things changed:

1. Phone cameras got smart. You don’t need a separate app anymore. Point your iPhone or Android camera at a QR code and it just works. That “download our QR reader app” step killed adoption for years.
2. People got used to them. COVID-era contactless menus trained an entire generation to reflexively scan anything square and pixelated.

Actually Good Uses for QR Codes

Business cards. Print a QR code that contains your full vCard (name, email, phone, LinkedIn). The person scans it and your contact info saves directly to their phone. No more typing. Use a QR business card generator to create one with your info baked in.

Wi-Fi sharing. Generate a QR code with your network name and password. Guests scan and connect. No more spelling out “the password is lowercase-b-uppercase-R-seven-exclamation-mark.”

Payment links. Freelancers: put a QR code on your invoice that links directly to your payment page. Fewer “oh I forgot to pay” excuses.

Portfolio links. Stick a QR code on your physical portfolio, poster, or art print that links to your online work. Bridge the physical-digital gap.

How to Make a QR Code That Works

1. Generate it right. Use a QR code generator that runs locally in your browser. No account needed, no data collected.
2. Test it. Always scan your QR code with at least two different phones before printing 500 copies. Use a QR code reader to verify the data is correct.
3. Make it big enough. Minimum 2cm x 2cm for close-range scanning. Bigger for posters or signs.
4. Add a call to action. A QR code by itself means nothing. Add “Scan for menu” or “Scan to connect” next to it.
5. Don’t put it on a billboard at 60mph. Nobody is scanning your highway ad. Physics won’t allow it.

QR Code Crimes to Avoid

• Linking to a non-mobile-friendly page. The person is on their phone. If your landing page isn’t mobile-optimized, you’ve wasted everyone’s time.
• QR codes in emails. The person is already on their phone reading the email. Just use a regular link.
• Broken URLs. If the URL behind your QR code changes, every printed code becomes useless. Use a URL shortener or redirect.
• No contrast. QR codes need strong contrast to scan. Dark on light, always.

The Future of QR Codes

They’re not going anywhere. Apple and Google are building deeper QR integration into their operating systems. Payment systems worldwide rely on them. And honestly, they solve a real problem: getting a URL from the physical world into your phone without typing.

Just please stop putting them on tombstones. Yes, that’s a real thing. No, we don’t want to scan grandma.
