Parcel-locker pickup sequence Four actors: customer, kiosk, booking service, and locker. The customer scans a pickup code. The kiosk validates it. If valid, the kiosk unlocks the locker and marks the booking collected after the door opens. If invalid, the service rejects the code and the kiosk shows an error. The locker stays locked. alt [ valid code ] [ invalid code ] Locker stays locked Scan pickup code1Validate code2Valid booking response3Unlock locker4Door opens5Mark collected6Invalid code response3aShow code error4a CustomerParcel recipientKioskPickup interfaceBooking serviceBooking authorityLockerPhysical compartment RequestResponse / eventProcessingTime flows ↓ Parcel-locker pickupSEQUENCE DIAGRAM / 01
