Digital business cards at trade fairs: share, collect, follow up

A trade fair is where a business card works hardest and where it is wasted most. Nobody knows how many of the hundreds of printed cards handed out over three days are still on a desk the following week. A digital business card makes those three days measurable: who opened the card, who left contact details, what happened on which day. This article covers preparation before the fair, sharing at the stand, collecting contacts and following up afterwards as a single flow.

Before the fair: three preparations

Update the card page for the fair. Are the title, phone and email correct; is there one sentence about the fair on the card page ("At the X fair this week, stand B12")? That is the advantage of a digital card: when the fair ends the sentence goes and the card stays. Prepare the QR and NFC. Print a large QR for the stand desk and the badge; if the team carries NFC cards, test the day before with two phones that the cards open the card page. Size and contrast rules are in the QR article. Turn on the contact form. The form on the card page lets a visitor leave a name, email and optional phone number; during the fair it becomes the stand team's notebook.

At the stand: the ten-second share

At a fair conversations are short and the noise is loud. Sharing should take no more than ten seconds: say "let me show you my card" and hold up the QR, or bring the NFC card close to the visitor's phone. When the page opens, the first thing the visitor should see is the name, the company and a "Save contact" button. That is all. The visitor saves, the conversation continues. Take the other person's printed card too; a digital card is not a one-way exchange.

A large QR placed on the stand desk works even while the team is busy: a waiting visitor scans the code and writes "call me" in the contact form. Over the course of a fair, the most contact requests often come from that desk code.

Collecting contacts and privacy

The name, email and phone a visitor leaves are personal data. Below the form it says that the details are passed only to the card owner, with a link to the privacy policy; because the visitor fills in the form themselves, the collection is voluntary. Even so, the stand team should not take the visitor's phone and fill in the form for them; that damages trust and blurs where the data came from. The visitor's own phone, the visitor's own hand.

Collected requests are listed per card in the team panel; which card's page they came from and when is visible. At the end of three days the list is in one place; nobody has to gather the stack of business cards from everyone's pockets.

After the fair: the 72-hour rule

The first three days after a fair are the most valuable time for follow-up; after that the visitor's memory fades. Day one: a short, personal email or message to those who left a contact request (remind them of the topic you discussed in one sentence). Day two: a general thank-you and a short piece of information for those who opened the card and saved it but left no request. Day three: one meeting inside the team about who spoke to whom, who is interested and what the next step is. Because the cards live in the company account, everyone comes to that meeting with their list ready.

What to measure

Three numbers for fair week: card page views, link clicks, contact requests. Compare them with the previous week and across the team's cards. The ratio of views between the stand code and personal cards tells you whether the stand layout worked; the number of contact requests is the first concrete return on the money spent on the fair. The seven-day trend shows the fair days and the follow-up week side by side. See the analytics article for how to read the measures.

Common mistakes

Opening a separate card for the fair. Duplicating the card splits the analytics; temporarily adding the fair sentence to the one card is enough. Forcing visitors to install an app. The card page opens in the browser; every step that needs an app is a loss at a fair. Printing the QR too small. The code on the stand desk should be readable from a metre away; the one on the badge at least three centimetres. Leaving follow-up until next week. The three-day rule; after that it goes cold. Keeping the collected list in personal accounts. If the cards live in the company account, so does the list; the connections stay even if a person leaves. See the team management article for the team setup.

Getting started

A week before the fair, open your card with a free sign-up, print the stand QR and show the team the ten-second share once. You will find how NFC cards work in the NFC article and the whole product on the digital business card page.
