Scanning and gate management

The free Marii gate app validates every QR instantly, rejects duplicates, and keeps checking people in even when the venue has no internet.

What is the Marii gate app?

The Marii gate app is the free check-in tool for your event entrance. Gate staff scan each buyer's QR code straight from their phone screen, and the app validates it instantly against your guest list. Every ticket QR is one-time use, so once someone is in, that ticket cannot be used again. There are no gate fees and no limit on scanning devices.

Running your gate on event day

1

Set up your scanning devices

The gate app is free and runs on any device — a phone, a tablet, whatever your team has. Use as many devices as you need: one at each entrance, an extra for VIP, a spare for the rush. There are no per-device or gate fees.

Get the gate app at gate.marii.app on each device you plan to scan with.

2

Open the app while you still have signal

The gate app caches your guest list, so check-in keeps working without internet. Open the app and load your event before the crowd arrives — once the guest list is cached, patchy venue signal will not stop the queue.

3

Scan each QR at the gate

Point the device at the buyer's QR code — shown from their ticket link, an Apple or Google Wallet pass, or a screenshot. All three carry the same code, so any of them scans fine.

The app validates each QR instantly. A valid ticket is checked in on the spot and marked as redeemed.

4

Let the app handle duplicates and invalid codes

Every QR is one-time use. After the first scan, the ticket is marked as redeemed — if the same QR is presented again (a forwarded screenshot, a re-shown ticket), the duplicate scan is rejected and gate staff can see the ticket has already been used.

A QR that does not belong to your event or is not a genuine Marii ticket simply will not validate, so fake codes fail at the gate rather than getting through.

5

Check groups in together

When someone bought tickets for a group, each person still has their own QR — but the group admission option lets your gate check the whole party in together instead of scanning them one by one. Useful for tables, crews, and family bookings.

One detail worth knowing: a ticket's holder name can be edited by the buyer up until the moment it is scanned. After scanning, the name locks.

What happens when the internet drops

Venue connectivity in Zimbabwe is not something to bet an entrance queue on — so the gate app is built to work without it. The app caches the guest list, and check-in keeps working offline: tickets are still validated, redeemed tickets are still rejected, and the queue keeps moving.

Buyer side too: attendees do not need data at the gate either. A screenshot of the QR, or a wallet pass saved in advance, scans exactly the same as the live ticket page.

Frequently asked questions

How does ticket scanning work at a Marii event?
Gate staff use the free Marii gate app to scan each ticket QR code straight from the buyer's phone screen. The app validates each QR instantly — a valid ticket is checked in on the spot, and the guest list updates.
How many devices can I scan with?
As many as you need. The Marii gate app is free, runs on any device, and there are no gate fees — so you can put a scanner at every entrance.
Does scanning work without internet at the venue?
Yes. The gate app caches the guest list, so check-in keeps working offline. Even with no signal at the venue, the queue keeps moving.
What happens if someone tries to use the same ticket twice?
Each QR code is one-time use. After the first scan the ticket is marked as redeemed, and any duplicate scan is rejected — the app flags it so gate staff know the ticket has already been used.
Can buyers show a screenshot of their QR code?
Yes. A screenshot of the QR is fine at the gate — the code is identical whether it is shown from the ticket link, a wallet pass, or a saved image. Whichever copy is scanned first redeems the ticket.
How do group tickets work at the gate?
Each person in a group purchase has their own ticket link and QR code, and there is a group admission option to check everyone in together at the gate.

Gate-day checklist

  • Decide how many entrances you need and assign a device to each
  • Get the gate app onto every scanning device before event day
  • Open the app and load your event while you still have signal, so the guest list caches
  • Brief gate staff: valid tickets check in instantly, duplicates are rejected automatically
  • Use group admission for tables and parties to keep the queue moving
  • Charge your devices — the app scans all night, batteries do not
