The payment method includes: a server receives a passwordless payment request transmitted from a terminal, and receives a current neighboring apparatus identifier search-detected and reported by the terminal; the server performs, according to the current neighboring apparatus identifier, and a corresponding relationship of a preconfigured terminal and a neighboring apparatus identifier, risk evaluation on the terminal, to obtain an overall risk evaluation score; and the server determines, according to the overall risk evaluation score, a passwordless payment strategy corresponding to the passwordless payment request. The server performs the risk evaluation on the current surrounding environment of the terminal to obtain the overall risk evaluation score, and then determine, according to the overall risk evaluation score, security of the current surrounding environment of the terminal, and determine the corresponding passwordless payment strategy corresponding to the passwordless request."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Payment method and device","description":"A payment method and device are provided.
