Trade show leads via QR code: contacts without typing.
At a trade show, good conversations end with a business card, a note on the clipboard or a badge scan, and a week later half of them are unusable. This guide shows where trade show leads get lost and how visitors leave a verified contact at your stand with a QR code.

Which leads can you still follow up?
Tap the leads you think are lost, then reveal.
-

-
Lost Interest noted, contact details forgotten.
-
Lost Typed up three days later, with a typo in the domain.

-

Sign-ups by message. No form, no code.
Sendity is a sign-up widget for your website. Instead of filling in a form, your visitors send one short message via WhatsApp or email. Sendity checks who it came from and hands your site the name and the confirmed phone number or email address.
See how Sendity works →-
One message instead of a form Visitors tap send in WhatsApp or their email app. Nothing to type, no confirmation email to click.
-
Confirmed by the message itself The contact comes from the sender of the message, so typos and made-up addresses never reach your list.
-
Pay per confirmed contact Start with 1,000 free credits, no credit card. After that, prepaid packages with no subscription.
Between the conversation at the stand and the first follow-up lie a noisy hall, a stack of cards and several days.
Cards and clipboards
Someone has to type them up after the show. Handwriting, blurred photos and typos cost contacts, and by the time the follow-up goes out, the visitor has forgotten your stand.
Badge scanners
The organiser’s scanners are fast, but they are rented per device and deliver what visitors entered at registration. Whether that includes consent to hear from you is a separate question.
QR code to a form
Better than paper, but typing an address on a phone in a noisy hall is exactly what nobody wants to do between two conversations.
QR code to one message
With reverse OTP, the visitor scans and sends one prepared WhatsApp message or email. The contact is verified before they leave your stand.
Follow up while they remember
Verified contacts arrive during the show, not after a week of typing. Your follow-up can go out the same evening.
At the stand in three steps.
From the conversation to a verified contact in a few seconds.

Trade show leads: common questions.
What if the hall has poor reception?
The message goes out as soon as the phone has a connection again. As long as the code is valid, it still counts.
May I send marketing emails afterwards?
Only with consent. Ask for it separately at the stand or in the first follow-up, and keep a record.
Where do my conversation notes go?
Into your CRM, next to the verified contact. Sendity delivers the contact; notes stay with you.
Do I need a separate campaign per show?
It helps: then you can see which show brought which contacts.
