# What is a scan in Fidella?

A scan is a staff member identifying a customer, by reading their QR code or entering their six-character code. It opens a bounded session in which staff can add stamps, redeem rewards and handle vouchers for that customer, at that venue, for a limited time.

Nearly everything that happens at a counter starts with a scan.

## What a scan does

It resolves who the customer is and what they hold at this venue. It does not
itself add or spend anything; the staff member then chooses an action.

## It is bounded

A scan is not an open licence. It opens a session with a deadline, tied to the
staff member who performed it and the venue they are signed in at.
