The utility model relates to a terminal. Last first draw -in groove (1), bluetooth card -writing module (2) and main control board (3) of being provided with of terminal, wherein, first draw -in groove (1) is used for packing into and waits to issue the SIM card, main control board (3) are passed through terminal from the area bluetooth communication module with bluetooth card -writing module (2)are establish bluetooth communication and are connected, and bluetooth card -writing module (2) still with first draw -in groove (1) intercommunication, and main control board (3) and both directly communicate first draw -in groove (1). Through above -mentioned technical scheme, wait that the distribution flow of issuing the SIM card can realize in same terminal, simplify the distribution flow ofwaiting to issue the SIM card, improve distribution efficiency. In addition, can reduce the occuping of terminal inner space, reduce the change dynamics of hardware to the suitability of extension bluetooth card -writing module further promotes the user and uses experience.
