POS machine preventing information disclosure

Abstract

The invention provides a POS machine preventing information disclosure. The POS machine comprises a shell, a circuit board, and a displayer, an input keyboard, a card reader and a printer which are electrically connected with the circuit board. The circuit board is a data processing center, and the circuit board is fixed in the internal part of the shell. The displayer is fixed at the upper part of the front surface of the shell. The input keyboard is fixed at the lower part of the front surface of the shell. The card reader and the printer are respectively fixed at one side of the shell. An obliquely arranged input keyboard baffle plate is fixedly arranged on the front surface of the shell. The input keyboard baffle plate is U-shaped and arranged at the front end and the left and right sides of the input keyboard. According to the POS machine preventing information disclosure, disclosure of customer information can be avoided by the input keyboard baffle plate made of polarized glass through reflected light rays when a customer inputs the information. A fixing frame is applied in the POS machine preventing information disclosure so that bagging carrying of the POS machine can be avoided, the POS machine can be directly hung at the waist, taking and using of the POS machine can be facilitated, and colliding of the POS machine in the carrying process can also be avoided.

Description

technical field [0001] The invention belongs to the field of POS machines, and in particular relates to a POS machine which is easy to carry and has good confidentiality for user input information.
