When your car is parked and you're not there
A tow, a clamp, a blocked driveway, a bump in a car park — most drivers only find out later. MyQR is a small sticker on your windscreen. Someone scans it, picks a reason, and you get the message. Your phone number stays private. Nothing is automatic; a person has to scan and choose to contact you.
They scan → choose a reason → you get the alert.
