The invention discloses a security encryption and communication method for an electric power account number card. According to the encryption method, account number data is transmitted through NFC; 10 account numbers of the account number card are encrypted through three encryption algorithms, and all-sector encryption is carried out; when an account number encryption function at a card writing end is started, a front end carries out first communication encryption with a background card writing dynamic link library; after the dynamic link library obtains the encrypted account numbers, second encryption is carried out in the dynamic link library; when encryption is carried out, encrypted dynamic data is used as the key; third encryption is carried out on the card according to the hardware features of different cards, and the key is directly written into a physical circuit of the card. The communication method comprises the steps that data transmission between the account number card and a terminal information
