A new app called Kaucjonetka has been launched in Poland, allowing users to store their returnable container coupons directly on their phones. It addresses a simple yet familiar problem: paper receipts are easily lost or left at home when going to the store
After the launch of the container return system, users began to complain about the inconvenience of paper coupons. Machines issue receipts after returning bottles and cans, but if they are not used immediately, they have to be carried around — and it is at this moment that they are most often lost or forgotten.
The app’s creator wrote on LinkedIn that he wanted to solve this everyday problem. The idea was as simple as possible: to ensure that coupons are always at hand and do not turn into yet another lost receipt.
In the comments, many supported the idea. One user noted that he regularly forgets to take this «piece of paper» before heading to the store.
How does it work?
The user scans the barcode from the paper coupon, after which it is saved in the app. It displays the store, the refund amount, and the expiration date.
The developer emphasizes that the app is secure: data is not sent to servers and is stored only on the device.
Importantly, Kaucjonetka is not tied to a specific chain of stores — it can store coupons from different places. This is convenient for those who return containers at various machines
Another useful feature is a reminder about the expiration date of the coupon.
