Our ROI is built on receipts. Not models.
Every euro of Reward Media budget is traced to the real purchase, at the till. No probabilistic attribution, no inference: receipts, amounts, dates. An ROI your finance department can audit.
- Verifiable by an external auditor
- Auditable receipt by receipt
- Zero inference, zero cookies
The end of estimated ROI.
72% of marketers can no longer measure their ROI since the end of cookies (IAB Europe / Ipsos). Fidecoin starts again from the only indisputable data: the till receipt.
Traditional Retail Media sells you impressions, clicks and attribution models. At the end of the quarter, nobody can prove that a sale actually happened.
Fidecoin does the opposite. Every reward paid out is triggered by a real till receipt, sent voluntarily by the consumer. Proof of purchase comes before the reward is paid — never the other way round.
This is our Retail Intelligence layer: every receipt is analysed by AI in under 2 seconds — exact products, amounts, retailer, time. Factual data, shared voluntarily, not inferred.
The result: your marketing budget no longer funds assumed intent. It funds transactions observed at the till, one by one.
An ROI built on real receipts — not on attribution models.
A calculation so simple that it becomes auditable.
Three lines. No black box. Every variable can be rebuilt from the raw data: receipts, timestamps, amounts paid.
Incremental revenue = (basket × frequency × members) − pre-campaign baseline
We measure the revenue of active members, then subtract the pre-campaign baseline. What remains is the revenue your budget actually created. Pilot example: 500 members × €45 basket × frequency ×2.4 vs pre-campaign baseline = €31,500 of incremental revenue per month.
Sponsor ROI = incremental revenue ÷ budget activated
A division, not a model. The incremental revenue observed at the till, divided by the budget you committed. Your management control team can redo the calculation line by line.
€1 of budget = 1 real purchase traced
Every euro activated is linked to an identified receipt: products, amount, retailer, date. Not a banner seen, not an assumed click — a trip through the till. The reward in real cash is paid via Open Banking in ~30 seconds, only after proof of purchase.
The receipt, matched with the transaction
With the consumer's consent, Fidecoin connects to their bank account via Tink (Open Banking) and matches each till receipt with a real bank transaction. The receipt proves what was bought; the account proves the payment. This double check is what makes the ROI auditable.
Two proofs are better than one: the receipt and the transaction.
How Fidecoin verifies that a purchase really took place — and was really paid for.
A till receipt says what was bought: the products, the amounts, the retailer, the time. But a receipt on its own remains declarative — it can be shared twice, picked up, forged. To build an auditable ROI, you need a second proof.
That is the role of bank reconciliation. With their explicit consent, the consumer connects their bank account to Fidecoin via Tink, Visa's Open Banking infrastructure, within the European regulatory framework (PSD2). Every shared receipt is then matched with the corresponding bank transaction: same amount, same retailer, same date.
The matching is automatic and silent. If the receipt matches a real transaction, the reward goes out. If it matches nothing, it is discarded — no reward, no data, no fraud.
The result: every line of your dashboard rests on a double proof. The receipt proves what was bought. The bank transaction proves the payment. Your budget only rewards purchases that were actually paid for.
It is this reconciliation that separates declarative measurement from auditable measurement — and that makes it possible to trace every euro of budget to a verified act of purchase.
Results measured at the till, not in clicks.
