Networking at Conferences? How to Share Your Portfolio and Contact Details With One QR Code
At a conference you have about ten seconds before the next conversation starts. One QR code that opens your digital card, with your portfolio, save-contact and booking link behind it, is enough to make those seconds count.
The simplest way to share your portfolio and contact details at a conference is one QR code that opens your digital business card. The card shows who you are, saves your details to the other person's phone in one tap, and links to your portfolio page and booking link, so one scan covers all three jobs.
This guide is about the conference itself: where to show the code (badge, lanyard card, phone lock screen, slides), what someone sees in the first few seconds after scanning, the short web address to print underneath for when scanning fails, and how to follow up afterwards. If your main goal is turning a scan straight into a booked meeting, our guide on how QR codes can turn networking into booked meetings covers that route in depth.
How does one QR code share your portfolio and contact details?
A QR code is only an address. What makes it useful is where that address goes. If it opens a long website home page, most people will close it. If it opens a short digital business card built for phones, they can save you, glance at your work and book time, all before the coffee break ends.
The chain behind one code
- QR code opens your digital business card link.
- Digital business card shows your name, role, photo and a short line on what you do, with a save-contact button (a vCard the phone adds to contacts).
- Portfolio or LinkDock page is one tap away from the card, holding your case studies, brochure and price guide.
- Booking link is also on the card, opening an event type such as a 20-minute follow-up call.
In Calenix, digital business cards are shared by link and QR code and include save-contact. You edit details once and the link stays the same, so a QR code printed today keeps working after you change job title or phone number. A Free account includes one card and one LinkDock page; Individual includes three cards. If you also carry an NFC tag, it can open the same card link with a tap.
What the scanner should see first
The top of the card, before any scrolling, decides whether the scan is worth it. Put these above the fold on a phone:
- Your photo, name and role, so they remember which conversation this was
- A one-line description, for example "Heritage building surveys across Cornwall and Devon"
- Save contact
- View portfolio
- Book a call
Everything else, such as social links and address, can sit below. Our guide to a digital business card that gets bookings covers the card layout in more detail.
Where to show the code at a conference
- Lanyard card. A credit-card-sized insert behind your name badge, printed with your QR code and short web address. The badge itself often carries the organiser's own code for lead retrieval, so do not cover it; add yours on the reverse or as a separate card.
- Phone lock screen. Save an image of your QR code as your lock screen wallpaper. You can show it while the phone is still locked, with no app to open, which is handy in a crowded hall. Turn the screen brightness up.
- Presentation slides. If you are speaking, put the code on your first and last slide, large enough to scan from the middle of the room, and leave the last slide up during questions.
- Stand or table sign. If you have a stand, an A5 sign at eye level with "Scan to save my details and see our work".
A short web address as a fallback
Some people cannot scan: older phones, bright light, a cracked camera, a reluctant colleague. Print a short, readable address under every code. On Individual, a branded custom domain and removal of Calenix branding make that address shorter and more obviously yours. Check how short your card link can be and test it by typing it on a phone.
Why one code beats a pocket of paper cards
Conferences produce lots of conversations and very few follow-ups. Paper cards end up in a hotel bag, and the person who meant to look at your portfolio forgets your name by Monday. A saved contact on their phone, with your photo and a link to your work, survives the trip home.
One code also removes the awkward moment of choosing what to share. Without it, you end up saying "I'll email you the portfolio" and then having to remember. With it, the portfolio, the contact details and the booking link all go across in one scan, and the next step is in their hands as well as yours.
It saves money and waste. Illustratively, if you hand out 150 paper cards across a two-day event at 10p each, that is £15 a conference, and most of them are binned. The bigger saving is time: each portfolio email you no longer need to send after the event is a few minutes back.
The follow-up is still yours to do. A scan proves interest, not intent. Scan the paper cards you receive into your contacts, add notes while you remember, and send a short message within two days. Our guide on how to turn a business card into a lead walks through that process.
What one conference QR code gives you
One scan, three jobs: contact details, portfolio and booking link all travel together.
Saved properly: save-contact adds you to their phone instead of a pile of paper.
Always current: you can edit the card after printing and the code still works.
Works when you are busy: a lock screen code can be shown in a second.
A fallback for every scanner: a short printed address covers phones that will not scan.
Better follow-up: a booking link means interested people can pick a time themselves.
How to set up one QR code for your next conference in 6 steps
Tidy your portfolio page — Put your best three to six pieces, brochure and price guide on a LinkDock page, with the newest and most relevant work first.
Build the card for a phone screen — Create your Calenix digital business card with photo, name, role, one-line description, save-contact, portfolio link and booking link above the fold.
Set up a follow-up event type — Create a 20-minute call with two booking questions, such as company and what they would like to discuss, so post-conference calls start prepared.
Produce the code in every format — Download the QR code for a lanyard card, a lock screen image and your slides. Print the short web address under each one.
Test with three different phones — Scan from different distances and in bright light, tap save-contact, open the portfolio and book a test call before you travel.
Follow up within two days — Scan the paper cards you collected, add notes and tags while the conversations are fresh, and send each person a short, specific message.
Where to show your conference QR code
| Feature | Best moment | Watch out for |
|---|---|---|
| Lanyard card behind your badge | Quick chats in the hall | Do not cover the organiser's badge code |
| Phone lock screen | Crowded rooms and queues | Low brightness and screen glare |
| First and last slide | When you are speaking | Code too small to scan from seats |
| Stand or table sign | Exhibiting at a stand | Placing it below eye level |
| Paper card with code | People who prefer paper | Out-of-date details if you reprint rarely |
Best practices for conference QR codes
Point every code at the same card link so you only maintain one destination.
Keep save-contact, portfolio and booking above the fold on a phone.
Print a short readable web address under every code.
Add a caption such as "Scan to save my details" so people know what they will get.
Test in bright light and from slide-viewing distance before the event.
Write a note on each new contact the same evening.
Ask before adding anyone to marketing emails; a scan is not consent.
Common conference QR mistakes
Linking the code to a website home page that is slow on mobile.
Making the portfolio the first thing people see instead of who you are.
Covering the organiser's badge code with your own sticker.
Using a code on slides that disappears before anyone can scan it.
Forgetting a fallback address for people who cannot scan.
Leaving follow-up until the following week, when names have faded.
Example: a building surveyor from Truro at a regional conference
Tom is a fictional heritage building surveyor based in Truro, Cornwall, who works on listed buildings and older homes. On Thursday 12 November 2026 he attends a one-day built environment conference and gives a 15-minute talk on damp in solid-wall properties.
His setup:
- Digital business card: photo, "Heritage building surveys across Cornwall and Devon", save-contact, "See recent surveys" and "Book a 20-minute call".
- LinkDock page: four case studies (a Grade II farmhouse, a Georgian terrace, a chapel conversion and a fisherman's cottage), a fee guide PDF and a sample report extract.
- Codes: a lanyard card behind his badge, a lock screen image, and his first and last slides, each with the short card address printed underneath.
During the day around 40 people scan his code, mostly from the final slide and during the lunch break. He comes home with 18 paper cards too. That evening he scans them into Calenix contacts with business-card scanning (the Free plan allows 10 scans a month, so he upgrades to Individual for 100), checks each one for misread details, and adds a note and a tag such as "conference, architect" or "conference, homeowner". Our guide on business card scanning explains why checking each result matters.
By Saturday he sends each person a short email referring to their conversation, with his booking link. He only adds people to his quarterly newsletter if they ask, because a business card exchange is not consent to marketing under UK GDPR and PECR.
Illustrative maths: if 58 people (40 scans plus 18 cards) lead to six booked calls, and two calls become surveys at around £850 each, the day produces about £1,700 of work, against the cost of a ticket and a day out of the office. These numbers are illustrative only. For timing and wording of the messages, see our guide to automated follow-up emails.
