The invention relates to a vending machine technique and aims to solve the problem that a conventional openable self-selection vending machine is poor in electromagnetic shielding capability and low in system reliability. According to the technical scheme, an openable self-selection vending machine with the relatively good electromagnetic shielding capability comprises a cabinet and a door, wherein the door is mounted on the cabinet; the door comprises a double-layer transparent shielding plate; the double-layer transparent shielding plate comprises an inner plate, an outer plate and a partition strip; the outer side of the inner plate is connected with the inner side of the outer plate through the partition plate which winds for one circle, and then a hollow structure is formed; an electromagnetic shielding layer is arranged on the surface of the inner plate; or electromagnetic shielding layers are arranged on surfaces of both the inner plate and the outer plate. The vending machine has the beneficial effects that the electromagnetic shielding capability is greatly improved, the system reliability is remarkably improved, and the vending machine is particularly applicable to openable self-selection vending machines.
