Tickets, check-in and courses
From sign‑up to the door, on one platform.
Registration without an account, a ticket with a signed QR code by email and single-use check-in from a phone. No spreadsheet, no paper list, and a shorter line at the door.
No account for attendees · Signed QR · Check-in from the phone's browser
Selling tickets is half the job. The other half is event day.
Between registration and the door, the work turns manual, and that's where the team loses hours and control. Credencia closes those gaps.
Before
Registration by hand
A generic online form, a spreadsheet and every confirmation sent one by one.
With Credencia
Registration without an account. The ticket arrives by email, as a PDF with a signed QR code.
Before
A paper list and a line at the door
The front desk looks up names on a printed list while the line grows.
With Credencia
Check-in from the staff's phone: the QR is read in the browser, and each ticket works once.
Before
No record of who came in
A copied ticket gets in, and after the event nobody knows who actually came.
With Credencia
The signed QR rejects forgeries, a copy gets in only once, and every entry is recorded.
Credencia handles all three, from sign‑up to the door.
At the door, just point the camera.
The scanner runs in the phone's browser and reads the QR code with the camera. You get the result on the spot, and each ticket gets in once. Tap the buttons under the phone to see each result.
Entry approved
Valid QR, used for the first time.
Already used
This ticket was already scanned.
Invalid
The signature doesn't match: a tampered QR.

Certificate as a PDF, with public verification by QR code.
Hours per attendee, in a report ready to export.
The class platform comes from Iter: nothing else to hire.
What Credencia does today.
For the attendees, the organizers and the door staff of chambers of commerce, churches and community events.
Registration without an account
Attendees sign up in a few fields, with no account or password to create.
Ticket by email, with a signed QR
A PDF ticket with a digitally signed QR code, so forged tickets get rejected.
Ticket page from a private link
Each attendee reopens the ticket from a private link, with no password.
Reminders before the event
Credencia reminds attendees before the event, so nobody on the team has to.
Self-service cancellation
Attendees who can't make it cancel on their own, without emailing the organizer.
Single-event site
Credencia can serve as a single event's website, with registration and tickets in one place.
Run the whole event from one dashboard.
Attendees, comp tickets, discount codes, price tiers and the door staff, all in the organizer's dashboard.
See who registered and who already came in
Send comp tickets to guests, speakers and sponsors
Create discount codes and price tiers
Give the door staff logins that open only the scanner
The first event site went live in August 2026, for an in-person seminar with 120 seats in Brazil.
