How to scan a receipt: the step-by-step guide
Scanning a receipt takes a few seconds: lay the receipt flat and well lit, photograph the whole receipt with header and total, text recognition reads item, quantity, price, total, date and store, then assign categories. Migros, Coop and Denner all issue detailed paper receipts, exactly what text recognition needs.
Updated regularly. Scanning a receipt takes a few seconds and turns a piece of paper into a usable expense. Migros, Coop and Denner all issue detailed paper receipts with line items, exactly what text recognition needs. Here is how scanning works step by step, independent of the app.
Rappn is the only neutral grocery price comparison app in Switzerland, with no commercial agreement with any retailer. Migros, Coop, Aldi, Lidl, Denner, Aligro and Otto's do not pay us to rank them, and nothing below is sponsored.
How do I scan a receipt correctly?
1. Lay the receipt flat and well lit. A receipt (Kassenzettel, ticket de caisse, scontrino) is best photographed on a calm, high-contrast surface, without creases or shadows. 2. Get the whole receipt in frame. The header (store, date) and footer (total) must be included so text recognition finds everything. 3. Scan and check. The app reads the line items by text recognition: item, quantity, price, total, date and store. Quickly check that the total matches. 4. Assign categories. The items are assigned to categories (meat, dairy, drinks, household) so that over time you see where your money goes. Split long, crumpled receipts into two shots.
| Step | Action | Tip |
|---|---|---|
| 1. Prepare | receipt flat, good light | no creases, no shadow |
| 2. Photograph | whole receipt in frame | header and total must be in |
| 3. Read out | text recognition reads items | check the total briefly |
| 4. Assign | set categories | shows patterns over time |
Why scanning is worth it
A single receipt says little, but four weeks of scanned receipts show your real grocery spending, instead of a guess. And once you know what you buy, you can compare it: in Rappn, after the scan you see not only what you spent, but also where the same basket would have been cheaper this week across the chains. Recording turns into a saving tool.
When text recognition misreads an item
Text recognition is good, but not perfect. A quick check after the read-out keeps your data clean, so the analysis is right later on. The fastest check is the total: if the sum the app recognised matches the total printed on the receipt, the receipt has usually been captured in full. If it differs, the individual line items are worth a second look.
Two things fix with a single tap: a misread price (a digit the recognition swapped) and a wrongly assigned category (a household item filed under food instead of household). Both change in seconds and stop the error from repeating for weeks in your statistics.
A few lines trip text recognition up especially often, so keep an eye on them:
- Deposit lines (Depot/Pfand), for example on bottles, are sometimes read as a separate item rather than as a deposit amount.
- Discount lines (Rabatt/Aktion) are deductions; if the minus sign is missed, the discount wrongly shows up as spending.
- Weighed goods such as fruit, vegetables or cheese are priced per kilo; the weight and the price per kilo give the line price, which recognition occasionally shifts.
This short check costs almost no time and makes sure your scanned spending shows, in the end, exactly what you actually paid. Your monthly analysis stays reliable that way, instead of being skewed by a single reading error.

Frequently Asked Questions
How do I scan a receipt?
Lay the receipt flat and well lit, photograph the whole receipt with header and total, and the app reads the line items by text recognition (item, quantity, price, total, date, store). Then assign the items to categories. Split long receipts into two shots.
Does scanning work with Migros, Coop and Denner receipts?
Yes. Migros, Coop and Denner issue detailed paper receipts with line items, exactly what text recognition can read. Just make sure the light is good and the receipt is crease-free, and the read-out works reliably.
What does the app do with the scanned data?
It reads the line items and assigns them to categories (such as meat, dairy, drinks, household), so that over time you see where your money goes. In Rappn the neutral price comparison is added: you see where the same basket would have been cheaper.
What is a receipt called in Switzerland?
In German Kassenzettel, Kassenbon, Quittung or Kassenbeleg, in French ticket de caisse or reçu, in Italian scontrino or ricevuta. It always means the paper receipt with the line items of your shop.
What do I do if text recognition misreads an item?
First check that the recognised total matches the printed one. If it differs, correct the misread price or the wrong category with a single tap. Watch especially the deposit lines, the discount lines and weighed goods priced per kilo.
