The present invention relates to an electronic payment system using fingerprint and finger vein recognition, the electronic payment system comprising: a communications network； and a payment service server which receives the first fingerprint and finger vein information from a client through the communications network, matches the first fingerprint and finger vein information to a payment means, registers the fingerprint and finger vein information, compares the first fingerprint and finger vein information to the second fingerprint and finger vein information when the second fingerprint and finger vein information is transmitted from the member store client, processes authentication of the client, and performs processing to enable payment to be performed by the payment means corresponding to the first fingerprint and finger vein information. An authentication device unit (2100) which obtains fingerprint and finger vein information has an authentication device unit space (2500) which allows the fingerprint and authentication device unit (2100) to be inserted therein, is formed on a lower end corner of a smartphone main body lateral side unit (2400), and is in the shape with a narrow upper portion and a wide lower portion. A fingerprint recognition module (2310) is formed on an upper side of the main body lateral side unit (2400). A vacant space is formed on a lower side of the main body lateral side unit (2400) to allow a finger (f) to be placed thereon. The authentication device unit space (2500) comprises an image sensor ( 2510a), an infrared ray emission unit (2520a) which makes photographing the finger (f) possible and a recognition circuit mounting unit which controls the same. Provided is the electronic payment system using fingerprint and finger vein recognition, the electronic payment system embedded in an edge of a smartphone.본 발명은 지문 및 지정맥 인식을 이용한 전자 결제 시스템에 있어서: 통신망과； 상기 통신망을 통하여 상기 고객 클라이언트로부터 제1 지문 및 지정맥 정보를 받아서 결제 수단에 대응시켜 등록하고, 상기 가맹점 클라이언트로부터 제2 지문
