Terminals: short contact, clear data
A passenger spends a few minutes in a restroom or at a gate. The feedback channel has to fit into that time. With EnaFeedback, the passenger scans a QR code, picks a language and gives a hygiene rating or writes a short complaint on one screen. No account or app is needed.
Every report arrives with its location code, such as "International departures, 2nd floor, B gates restroom." The operations team does not have to work out where the problem is; they go straight there.
