Create One-time redeemable QR Code Coupons

How does a one-time redeemable coupon work?

A coupon that can be redeemed once works in such a way that you create a series of unique QR Codes that once scanned redeem the voucher. You can print these unique QR Codes or send them by email. The validation is done by you or an employee by scanning a unique QR Code.

You can redeem the voucher with any QR Code reader that is installed on a smartphone with an internet connection. As soon as the QR Code on the smartphone display is scanned, the voucher is redeemed.

You can also redeem the voucher without a QR Code scanner by tapping the redeem button below the QR Code.

Redemption process
The voucher can only be redeemed once. If the voucher is redeemed a second time, an error message appears.

9. Authorize devices

Optionally, you can authorize specific devices that can redeem the vouchers. If no device is authorized, any device can redeem them.

We offer a webapp-based redemption solution. This means you do not need to download any App to scan and redeem your QR Codes. You can use any QR Code scanner application and your device will be authorized once it scans the authorization QR Code.

You do not need to download any App to scan and redeem your QR Codes. You can use any QR Code scanner application.

You can assign a Name to each Authorized device. It will be displayed on the redemption stats for each voucher.

A fallback URL can be displayed in case an unauthorized device tries to redeem a voucher.

You can also set a password to the coupon to prevent accidental redemptions.

Mailchimp integration

One voucher per subscription

If you want to provide a unique coupon to a user when he subscribes to a Mailchimp mailing list, you can automatically do this by connecting Mailchimp with our platform through a Webhook.

After a new user confirms his subscription in Mailchimp he will receive a mail with a link to the one-time redeemable voucher.

You can embed unique redeemable QR Codes in any of your mail campaigns by using merge tags. Each user will receive an email with a unique QR Code that only he can redeem at the shop or restaurant. Learn more about how to send vouchers to a mailing list

Vouchers issuing

Unlike coupons with unlimited redemption or single redemption for one IP address, one-time redeemable vouchers have unique QR Codes that you have to issue once the offer is defined:

Max. Vouchers

Specify an optional maximum of vouchers allowed to be issued.

Time to live

Set a validity period in days that a voucher should be valid after the first scan. If the voucher is not redeemed in that period, it will expire.

Create bulk vouchers

Here you can specify how many unique QR Codes you want to generate for a onetime redeemable coupon . After creating the set of QR Codes you can download them at once in a zip file for further processing.

There are two types of QR Codes: the ones on forwarding to the landing page of the coupon and the others who will redeem the voucher after they have been scanned. If you click on Download, you will load the unique QR Codes that redirect to the mobile coupon.

If you click on QR Code Redeem, you are downloading the unique QR Codes that invalidate each voucher when scanned.

Issue per Lead

When you create a lead landing page, a customer will receive an email with a voucher when they complete the registration form. Each registration receives a one-time voucher per email. Any number of users can register.

Embed Unique QR Codes in Newsletters

If you want to send newsletters to your customers, you can include personalized QR codes in the emails.

Issue Voucher for New Subscriber

With Webhooks you can send event-based information to a customized URL. When an event e.g. VOUCHER_CREATED occurs, your given URL will be called (webhooked).


In the extras section in the coupon editor you can assign your own short URL for the voucher (vanity link) and decide if you want the search engines to index your voucher.

EAN-13 Barcode

You can set an optional EAN-13 barcode, that will be displayed after the coupon has been redeemed. This enables the cashier to scan the barcode and add the article to the cash register.

Optionally you can enable Webhooks that submit the EAN Code to your cash system. Learn more about Webhooks
