How a receipt scanning loyalty program works, starting with a shopper and a photo
ScanThe member takes a picture of the receipt and uploads it. It sits on their account as pending.
ReadOCR pulls the store, date, receipt number, totals and each line item.
CheckLines are matched to your products, then duplicate detection and your rules run.
ApprovePoints land on the qualifying products, and the member profile fills in.
They join your program first, then take a picture of their receipt and upload it, in more than one image if it's one of those receipts that's longer than the person holding it. The receipt attaches to their member account and sits there as pending while the system reads and checks it, so no points move yet.
Then the receipt gets read and matched to your products
Optical character recognition, or OCR, is the technology that turns a picture of text into actual text. It reads the receipt and pulls the store name and address, the purchase date, the receipt number, the totals and each line item.
Then each line is matched against the product list you give it, using product names, SKUs and UPCs. If you've ever looked closely at a store receipt, you know retailers abbreviate product names in ways only they understand. So the better your product list, the better the matching. It's work your team does once up front, and it pays off on every receipt after.
That's trial and re-trial, measured one member at a time, for a product that sold on someone else's shelf.
Receipt validation catches what shouldn't count
Duplicate detection checks for the same image, the same date and total, and the same receipt number, so a receipt sent twice, even as a new photo, gets flagged.
On top of that, you set the rules. Receipts older than a certain number of days, receipts missing key information, receipts with none of your products on them, and receipts where a line item's price and quantity don't match its total can all be handled. Depending on the rule, a receipt can be approved automatically, flagged for someone on your team to review, or rejected. Flagged receipts go to a review queue that keeps an edit history.
Now, being too strict hurts you as much as being too loose. If a member's real receipt gets turned away, they probably won't bother trying again. I'd start with more receipts flagged for review than rejected outright, then tighten the rules once you've seen what real receipts look like.
Once it's approved, the points land and the profile fills in
When a receipt is approved, points are calculated on the qualifying products using your program's rules. Any bonus promotion you're running applies at the same time.
Now look at what you have from just one receipt. You have a shopper you can contact, with a dated purchase at a specific store and the products they chose.
Their second receipt is a repeat purchase you can actually see. By their fourth, you know which store they shop at, how often they buy and what else they buy from you. That's trial and re-trial, measured one member at a time, for a product that sold on someone else's shelf.
Decide what a receipt should earn, because that shapes what shoppers do
Before you launch, you have to decide how a receipt turns into points. You can award points on what they spent on your qualifying products, so a bigger basket earns more. You can give a fixed bonus for buying one specific product, which is useful when you want trial on something new. Or you can run a multiplier for a set window, like a month where receipts from a particular product line earn double. You can also set limits, such as flagging any receipt where one item shows up in an unusually high quantity.
Each one nudges a different behavior. So start with what you actually want shoppers to do. If you're launching a new flavor, a fixed bonus on that product makes more sense than points on the whole basket. If you want existing buyers to come back sooner, reward the second and third receipt in a way the first one isn't.
You'll also decide how old a receipt can be and still count. Keep in mind that a lot of store receipts are printed on thermal paper, which fades, so a receipt that sat in a cup holder for three weeks is much harder to read. The best time to get one is right after the purchase, so remind members to upload soon after they shop. Write all of these answers down with whoever owns the program day to day, because they become the rules everything above runs on.
Decide what you keep, and tell members what you use
A receipt has a lot more on it than your product. It lists every other item in the basket, including other brands, and depending on the store it can show part of a card number or a retailer loyalty ID. Something to consider is deciding with your privacy and legal team what you actually need to keep and for how long, then telling members plainly what you do with their receipts and why. Being upfront is part of earning the right to keep asking.
Receipt scanning is a module you add to Rewards. If most of your sales happen at retail, our CPG page shows how it fits with the rest of a program.
Walk your own shelf the way your shopper would
The most useful thing I'd do before any of this is what I did on that customer experience review. Go stand in front of your own shelf, pick up a few different products from your line and ask whether any of them tell you the program exists. Then buy one, look at the receipt line by line and try uploading it the way a shopper would, on your phone, standing up, with one hand full.
And then ask your team a simple question. If a shopper uploaded this today, what would we know about them tomorrow, and what would we know after their fourth receipt? If the answer is not much, you've found the first thing to fix. If you want to see the whole process running in a real program, talk with our team.
Frequently Asked Questions
How does receipt scanning work in a loyalty program?
A shopper joins the program, takes a picture of their store receipt and uploads it. Optical character recognition reads the store, date, receipt number, totals and line items, and each line is matched against the brand's product list. The receipt is checked against the brand's rules, and once it's approved, points are awarded on the qualifying products.
Do you need a POS integration or retailer data for receipt scanning?
No. Nobody at the register does anything differently, and there's no point-of-sale integration or retailer data feed involved. The process starts with the shopper and their phone after they've already left the store.
How do you stop shoppers from uploading the same receipt twice?
Duplicate detection checks for the same image, the same date and total, and the same receipt number. On top of that, the brand sets rules for receipts that are too old, are missing key information, have none of its products on them, or have a line item whose price and quantity don't match its total. Each rule can approve, flag for review or reject a receipt.
What should a brand decide before launching receipt scanning?
Decide which products qualify and how they appear on a receipt, how a receipt earns points, how old a receipt can be and still count, and what receipt data you keep and for how long. Write those decisions down with whoever runs the program day to day, because they become the rules the whole process runs on.
