Summary:The invention discloses an NFC label data writing method and a terminal. The method comprises the following steps of acquiring a UID of each to-be-produced NFC according to a received label data writing request of a plurality of to-be-produced NFC, generating a ciphertext calculation instruction comprising a plurality of UIDs according to the UIDs, and sending the ciphertext calculation instruction to a background server, receiving calculation completion information which is sent by the background server and corresponds to the ciphertext calculation instruction, and obtaining a ciphertext corresponding to the UID according to the calculation completion information, and writing the ciphertext into the secret key area of the to-be-produced NFC based on the UID according to the received sealing test starting information of the plurality of to-be-produced NFC, and obtaining the to-be-produced NFC after the ciphertext is written, thereby realizing batch writing of NFC label data, not needing to formulate issuing e
