Qard™ scan

Qard™ scan is a secure day-to-day work tool for authorized staff at Qard
merchants. The app requires the merchant identifier, username and password
issued through the Qard platform. It does not offer public consumer
registration.

Main features:

- fast Qard card identification by QR code
- manual search by card number or encoded data
- display of merchant-balance and wallet operations allowed by the server
- review and confirmation before an operation is recorded
- separate merchant and wallet transaction histories
- password change and secure sign-out

The server is authoritative for card validity, available operations and limits.
When the network is unavailable, the app does not record or queue operations.

Sign-in details remain in platform-protected secure storage. Camera permission
is requested only when the QR scanner is opened, and manual search remains
available when permission is denied. During normal operation, raw QR content
and card data are not kept in persistent local storage.

Qard™ scan is not a payment app and does not handle real money.
