Promotion platform with AI receipt validation for Verkade

Verkade wanted to boost sales of its chocolate bars with a nationwide prize promotion. Shoppers buy a bar, upload their receipt and see straight away whether they've won. Your Tech Club built the platform: the campaign page, the automatic receipt validation and the dashboard where the team follows the promotion.

Why couldn't this be done with a standard promotion tool?

The promotion combined three requirements that standard tools don't meet together: peak load, automated receipt checks and full control over personal data. The bar's packaging couldn't be changed, so entry had to work through a photo of the receipt. Every entry then had to be checked for validity, and reading along manually wasn't an option at these volumes.

Then there was compliance. The platform processes participants' personal data and photos in line with the GDPR. Your Tech Club is ISO 27001 certified and the platform was set up according to those principles. That called for our own infrastructure rather than a third-party campaign tool.

How does entering work for the shopper?

In three steps: buy, upload, win. The landing page is mobile-first, because most people photograph their receipt with their phone in or just outside the shop. The shorter the flow, the lower the barrier to taking part.

After a valid upload, the participant taps a digital Verkade bar that breaks apart in an animation and shows straight away whether they've won a prize. Anyone who doesn't win is invited to try again with another flavour.

How are receipts checked automatically?

With Google Document AI. It reads the uploaded receipt, after which the platform looks for the Verkade products on it and checks whether the purchase meets the promotion's terms.

The platform also detects duplicate entries, so the same receipt can't take part twice. Together with limits per email address, per IP address and per day, that keeps the promotion fair without manual checks.

What does the Verkade team see in the dashboard?

The number of entries, the number of unique participants and the approved and rejected receipts, while the promotion is running.

• Winner management

  Winners are drawn according to rules set in advance, automatically or manually, with the full entry data alongside for verification.

• Export for follow-up

  Entry data can be exported to CSV, so the marketing team can analyse or follow up on the results themselves.

• Security as a starting point

  Front end and back end are separated, uploads are stored securely and traffic is encrypted. Logging, monitoring and rate limiting limit abuse.

What can Verkade do with it now?

The promotion runs on its own infrastructure, entries are processed automatically and the team keeps sight of the numbers and control of the data throughout.

The platform is modular. The campaign page, the receipt validation and the dashboard are separate from each other, so a next promotion can run on the same foundation.

At the end of the promotion, Verkade announced the winner of the €10,000 in a video on Instagram.
