The invention discloses a self-service deposit method and device and relates to the self-service deposit service technology. The problems that existing self-service deposit efficiency is low and mechanical faults are prone to occurring are solved. The self-service deposit method includes the following steps of reading of user information, authentication of user information, amount deposited inputting, currency packaging and storage of currencies into a storage box. The self-service deposit device comprises a card reader, a deposit mechanism, an inputting device and a central control system and further comprises a packaging machine which is connected with the central control system. The central control system controls the packaging machine to package the currencies and the deposit mechanism is used for storing the packaged currencies. According to the self-service deposit method and device, the currencies are not checked one by one, a great deal of time is saved, efficiency is improved, switching between the stored currencies and reimbursement currencies does not exist and the probability of mechanical faults is reduced. The self-service deposit method and device are mainly used for providing the self-service deposit service for users.
