Through the design of air tickets, the characteristic architectural silhouettes of travel destinations are combined with air tickets. After ripping off the deputy ticket, the ticket will leave the silhouette of the characteristic building, increasing the collection value of the ticket. The user will save the used ticket. The barcode on the ticket records the user's personal information. Because the existing ticket lacks interest, the user will also discard the ticket. This design will allow users to keep and collect air tickets unconsciously, preventing the leakage of personal information
