Scans in our door test

Six phones scanning at once. No ticket admitted twice.

The hard part

The door is the product.

Most ticketing tools are designed for the checkout. Mi Karchi is designed for the fifteen minutes when a thousand people meet five staff with phones.

Works with no signal

The full guest list is cached on the device. Scans queue locally and sync when the network returns.

No ticket gets in twice

A second scan says when and where the ticket was first used, so staff can settle it on the spot.

A printable fallback

A paper guest list per station, generated the morning of the event.

How it works

You bring the event. We set up the rest with you.

  1. Tell us the date and the headcount

    We set up the event page, your questions and the tickets with you.

  2. Share one link

    By email or WhatsApp. Registrations, the waitlist and tickets run themselves.

  3. Open the doors

    Staff phones become scanners, and our team stands at the door with yours.

Who it is for

Events where the door matters.

Staff celebrations and company events

Your own questions, like department and meal choice, counts from real registrations, and a report for your manager the next morning.

Conferences and public events

Open registration from one link, a waitlist when you are full, and attendance and no-show numbers afterwards.

Agencies

Run your client's registration and door with us. Your client gets a read-only view of their own event.

Before and on the night

You see everything, without chasing anyone.

Delivery you can check

Bounced and blocked invitations are listed per event, so you know before the door does.

Live arrivals

Watch the room fill, per station, as it happens. Nothing to refresh.

The report that night

Attendance, no-shows, arrivals over time, and the answers to your own questions, exported to CSV.

Questions before the demo

What if the venue wifi fails?
Every phone keeps the guest list and keeps scanning. Scans sync when the signal returns, and each station has a paper list as a last resort.
Do guests need an app or an account?
No. They register from a link and keep the ticket on screen and by email. If it goes missing, they enter their email and it is sent again.
Why not a form or a ticket marketplace?
A form collects names and a marketplace sells tickets. Neither sets up your event with you, shows whether invitations arrived, or keeps the door moving without a signal.
Where is attendee data kept?
In the United States, with Supabase and Vercel. Attendees never create an account, and we only ask what your event needs.
