Validate every proof of purchase, for loyalty, cashback and rebates

Customers take a photo of their receipt in your app or on your website after shopping, in-store or online. Mindee extracts the store, date and time, the receipt number, the total, and each line item with its description, quantity and price. Your program then checks which items are eligible and awards points, cashback or rewards automatically. For brands that sell through retailers they don’t own, this is one of the only ways to reward customers directly and collect purchase data at the product level, without depending on each retailer’s loyalty program.

Start by defining the rules: which products or stores are eligible, how many points each purchase earns, and what rewards customers can claim. Then add a receipt upload step to your app or website, and send each photo to the Mindee API, which returns the receipt data as structured JSON in seconds. A rules engine, whether your own or your loyalty platform’s, matches the line items with eligible products and credits the customer’s account. Mindee handles receipts from any retailer without templates, so you don’t need to build or maintain your own OCR, and you can launch a program across hundreds of stores right away.

A proof of purchase is a document showing that a customer bought a specific product. Usually it is a receipt that shows the store name, the purchase date, the product and the price paid, or an order confirmation or invoice for online purchases. For loyalty programs, promotions and cashback offers, the proof must also match the campaign rules: the right products, bought in a participating store, during the promotion period. Mindee extracts each of these elements, so eligibility can be checked automatically instead of having each receipt reviewed by your team.

The most common types of fraud are submitting the same receipt several times, sharing a receipt between accounts, uploading old receipts outside the promotion period, and editing amounts or products on the image. Because Mindee extracts the store, date, time, receipt number and total of every receipt, you can automatically detect duplicates across all users, reject receipts outside the valid period, and set limits per customer and per day. Receipts with low confidence scores or inconsistent totals can be sent for manual review, which protects your rewards budget without slowing down legitimate customers.
