Dimensional bookstore
There are basically 7 small icons on the transaction panel of the store's sales desk, namely the transaction platform, the dimensional main store and tasks, currency exchange, warehouse, counter, mail, and contacts. The whole column on the right side of the panel is basic information. The top is a small scanned avatar of a real person. The following lines say plane number: 1517, shop owner number: 1517, plane attribute: 1517, shop owner level: level 0 0%, shop owner permission: z, shop level: 0 (hidden), credit points: 0, plane currency: 0, shop owner activity: 0. [Only the shop owner can see these]
