A method, system and device for opening an electronic certificate, the method comprising the steps of: an issuing end sends an issuing request to a funds management server (S11); the funds management server starts to open an electronic certificate according to the issuing request (S12); within an issuing process, the issuing end sends an issuing amount alteration request to the funds management server (S13); upon agreeing to alter an issuing amount, the funds management server verifies the altered issuing amount (S15); after verification has been passed, the funds management server freezes funds or a credit limit, equal to the altered issuing amount, in a payment account and then opens the electronic certificate (S16). Opening an electronic certificate having a payment commitment function reduces the transaction risk, and allowing an issuing amount alteration request to be submitted at any time within an electronic certificate opening process without it being necessary to resubmit an electronic certificate opening request increases the flexibility and efficiency of opening the electronic certificate. |
