The invention provides a multifunctional electronic signature supporting continuous endorsement signature. The multifunctional electronic signature comprises an information processing part, a printing module, an electronic paper electronizing module, a reading-writing module and an information sensing module, wherein the information sensing module acquires prior endorsement signature data and transfers the prior endorsement signature data to the information processing part, and by using public key information of a prior endorser and private key information of an endorser as the key, the information processing part decrypts the prior endorsement signature data to obtain the prior signature information; and a cryptographic algorithm module performs the cryptographic operation treatment of the signature information and the prior signature information by using the private key information of the endorser and the public key information of an endorsee as the code to obtain the ciphertext information, and the ciphertext information is converted into the imaging signature data; and the ciphertext information is converted into the printing signature information. The multifunctional electronic signature improves the uniqueness of the signature information and makes the signature information more difficult to replicate; moreover, by adopting the mode of easy identification and use, the electronic signature realizes the effective signature of electronic bills, obviously lowers risk in using the electronic bills and enforces the development of modern financial industry.
