Event offers that can only be redeemed once.

Drink tickets, entry perks and sponsor offers as digital vouchers. Bar staff scan them with their own phones, and each bar signs in with its own login. A forwarded copy comes back Already redeemed, and you can see how many tickets have been redeemed so far, and which bar scanned each one.

Where event promotions go wrong

A drink ticket in a group chat gets claimed three times. A printed list stops the line while someone finds a name. And afterwards, nobody can say how many sponsor perks were handed out.

  • Screenshots at the gate

    One ticket gets shared across a group chat. Staff can't tell the original from the copy.Each guest has their own code. The second scan comes back Already redeemed.

  • The line stops for a list

    Checking a spreadsheet or a printed list at a gate or booth holds everyone up.Staff point a phone at the QR code and see Accepted or Already redeemed.

  • No record afterwards

    Who redeemed what, when, and how many in total? Guesswork.Every scan is logged with the time and the scanner login.

  • A workaround that fails at doors open

    A shared spreadsheet or clipboard holds up until everyone arrives at once.Each bar scans on its own phone. Need another lane? Sign in another phone.

From the guest list to the last drink

You decide how guests get their ticket and how staff check it. Coupon Carrier keeps track of every code in between.

  1. 1

    Create

    Import codes you already have, or let Coupon Carrier generate one per guest.

  2. 2

    Deliver

    By email with the ticket, on a printed handout, or as a personal link you send yourself.

  3. 3

    Validate

    Staff scan the QR code at the bar or the gate. The code is checked and locked.

  4. 4

    Track

    See how many tickets came back, and when. Scans also show which login made them.

Two ways to validate event vouchers

The scanner is built for bars and gates with several people on shift. Mark as Used suits a small venue where staff can take the guest's phone for a second. Both lock the code.

Scan the QR code

Staff sign in to the scanner in their phone's browser and point the camera at the ticket. One scan, and the code is redeemed.

  • Staff see Accepted, Already redeemed, Maximum redemptions reached, or Invalid code. You can reword these, in any language.
  • Each scan records the time and the scanner login. Staff can undo the last scan if they made a mistake.
How the QR scanner works

Tap Mark as Used

The guest opens their voucher. Staff tap the button on it and confirm. The voucher then shows the date it was used, so the next bar can see it has already been redeemed.

  • No login and no second phone. Good for a small venue or a VIP desk.
  • You choose the button text and the confirmation wording.
How Mark as Used works

Redemption tracking for the whole night

Every scan is tied to a scanner login and a time. When the last bar closes, the list is already there.

  • A login per bar, gate or sponsor booth

    Create as many scanner users as you need. The export tells them apart by login, so you don't have to.

  • Tickets that expire on their own

    Set a validity window from hours to weeks. When the weekend is over, the tickets stop working without any cleanup.

  • A CSV for the sponsor report

    Export scanned codes with the time and scanner user for each. For totals by event, date or tag, use the reports.

Event promotions venues actually run

Anything a guest should get once. The ticket looks different, the check is the same.

Running something else? Restaurants and retail Bars and breweries Car washes

  • Entry perks and welcome offers

    A welcome drink for everyone who booked early, scanned at the door.

  • Upgrades and add-ons

    A VIP upgrade or a backstage tour, redeemed once at the desk.

  • Early access and pre-sale incentives

    A voucher in the pre-sale email, checked at the gate on the day.

  • Sponsor activations

    A sponsor's giveaway, counted so you can report back the exact number.

  • Booth and concession promotions

    A free side at the food truck, claimed once per guest.

Frequently asked questions

Something else? Read the documentation

Can this handle high traffic volumes?
Yes. Everything runs in the browser, and each staff member scans on their own phone. A small tasting event and a festival with ten bars use the same scanner. The festival just signs in more phones, each with its own login.
Do we need dedicated scanners?
No. Any smartphone with a browser and a camera can scan QR codes with the web-based scanner. There's no app to install and no hardware to buy. You can also use Mark as Used, where staff tap the button on the guest's phone and confirm.
Can vouchers be redeemed offline?
No. Vouchers need an internet connection to validate and update their status. That is how each redemption gets recorded and a second attempt gets turned down. A normal mobile data connection is enough.
Can we see redemption stats after the event?
Yes. The scanned codes export lists every scan with the time and the scanner login that made it. Create a scanner login per gate, booth or staff member to see who redeemed what, and use tags to keep events apart. Reports show totals by event, date or tag, and both export as CSV for sponsor reporting or your own review.
How do we get started?
It's self-serve. Create an account, set up your first offer, import or generate codes, and share the link. There's no onboarding call, no integration project and no hardware.
