Frequently Asked Questions (FAQ)

Answers to the most common questions from our users.

In the wallet, click the Add Card button, select a store from the list (or enter a custom one), and scan the barcode with your camera or enter it manually. The card will be saved immediately.

Yes! Thanks to PWA (Service Worker) support, the entire app and your saved loyalty cards load from your device's local storage. This allows you to display your barcodes at the checkout even in areas without a signal.

Absolutely. We use a Zero-Knowledge architecture. Your data is encrypted directly in your browser using AES-256-CBC with a key derived from your password (PBKDF2). We never store your keys in plaintext on our servers, ensuring that only you can see your cards.

In the Family section, you can create a family group and send invitations to other members. The card sharing key is securely exchanged between your devices, encrypted using the public keys of the members. Once sharing is active, all members can see the selected cards in real time.

Yes, completely free. Priceri Wallet is developed as a free and community-driven alternative with no hidden fees, premium paywalled features, or advertisements.

Yes. Most modern checkout laser readers and 2D scanners can effortlessly read barcodes directly from your phone's screen. For older types of laser scanners, we recommend turning your screen brightness to maximum or asking the cashier to enter the card number manually.

If the code fails to render (e.g., due to a non-standard format), the app automatically uses a safe fallback format (Code 128) and displays the card number below it. In the card edit mode, you can try manually changing the code type (e.g., from EAN-13 to Code 128 or QR code).

In the Settings section of your profile, you will find a unique **Share Token** and a sharing link. By copying this token to another account or loading the link on another device, you can instantly synchronize your entire wallet.

Priceri Wallet works as an independent Progressive Web App (PWA) that you can install directly on the home screen of your iOS or Android device. Direct export to Apple/Google Wallet is not implemented in this local edition, as it requires external servers and certificates, which would compromise our Zero-Knowledge architecture and privacy protection.
