The invention discloses a self-service system for a hotel, comprising a self-service terminal, a server, a self-service management system for the hotel, network communication equipment and a door lock, wherein, the server is connected with a self-service terminal network, and the network communication equipment is used for connecting the server with the self-service terminal; the self-service terminal comprises an operation terminal, a guest recognition system, a membership card and a membership card transmitter-receiver device, wherein, the membership card is as the same as a card for opening the door lock. The self-service system overcomes the defect that the prior art can not provide self service for customers without the membership card; the member privacy has possibility of being leaked because the membership card stores the personal information of a member; and customer information is only reserved on a local server, thus sharing fails to be realized, and the possibility of data loss due to system faults and the like is easily caused. The invention provides a self-service system for the hotel, which can protect customer privacy; data is stored in a plurality of the servers to ensure data safety; customer information among the hotels can be shared; and the self-service system can be widely applied to the hotel field.
