The invention discloses an object storing and sharing method and an intelligent service system thereof. The object storing and sharing method and the intelligent service system thereof aim at solvingthe technical problems that existing storage cabinets only have a single function of storing objects but cannot have the sharing functions of object leasing, buying, selling and the like. The method comprises the steps of presetting a plurality of intelligent cabinets, wherein each intelligent cabinet is internally provided with a plurality of storage spaces, and an electromagnetic lock is arranged correspondingly to each storage space; obtaining storage space information and stored object information in each intelligent cabinet through a client side; conducting operation of storing, renting,leasing or purchasing through a client side, wherein the client side is linked with a cloud server, and the cloud server controls the corresponding electromagnetic lock to conduct an operation instruction. Each intelligent cabinet is provided with the storage spaces, operation of storing, renting, leasing, purchasing, sharing and the like can be carried out through the client side, the corresponding storage space is opened or closed, and therefore the defect that the current storage cabinets are monotonous in function is greatly overcome.
