The application relates to the technical field of mobile phone cases, and particularly discloses a multifunctional mobile phone case, which comprises a shell, an ink screen, a first magnetic attraction piece, a circuit board, an NFC antenna and a switch assembly. The shell is provided with a containing cavity, and the bottom of the containing cavity is provided with a display window. The ink screen is arranged at the bottom of the containing cavity, and the display area of the ink screen is located at the display window and used for displaying patterns. The first magnetic attraction piece is arranged on the side of the shell away from the containing cavity and used for being fixed by being attracted to a magnetic attraction accessory. The circuit board is arranged in the containing cavity and electrically connected with the ink screen, and the NFC antenna is arranged in the containing cavity and electrically connected with the circuit board. The switch assembly is arranged on the circuit board and partially exposed to the shell, and the switch assembly is used for connecting or disconnecting the connecting line between the circuit board and the NFC antenna. The multifunctional mobile phone case can connect or disconnect the connecting line between the circuit board and the NFC antenna of the mobile phone case through the switch assembly, thereby avoiding the problem that a card reader cannot read the NFC signal of the mobile phone.
