Specifically, when the server acquires that the NFC digital currency transaction mode is an active transaction, the server adopts the account information signature bound to the user terminal to authenticate the NFC digital currency transaction, for example: when the server acquires that the user terminal initiates a transaction in a mode of scanning a code through an APP (application), inputting an address of the other party, selecting a transaction address saved in the past and the like, because the NFC card is bound by the application account of the digital currency system through a unique card number, logging in the application account of the digital currency system through verifying the card number and the password information of the NFC card can pass through the unique card number, binding the NFC card, and obtaining active transaction signature authentication information after passing authentication. On the other hand, the blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The block chain (Blockchain) is a decentralized database, is used as a bottom-layer technology of the bitcoin, and is a series of data blocks which are generated by correlation by using a cryptographic method, and each data block contains information of a batch of bitcoin network transactions, and is used for verifying the validity (anti-counterfeiting) of the information and generating a next block. Therefore, in order to ensure the security of the current transaction, the active transaction signature authentication information is sent to a block chain to execute the transaction operation corresponding to the active transaction.
In addition, the executing of the transaction operation corresponding to the NFC digital currency transaction mode according to the NFC digital currency transaction mode further includes the following operations: when the NFC digital currency transaction mode is passive transaction, judging whether the acceptance terminal is an affirmation-free transaction acceptance terminal; when the acceptance terminal is the confirmation-free transaction acceptance terminal, the NFC digital currency transaction is signed and authenticated by the fingerprint module through a hardware signature algorithm to obtain first passive transaction signature authentication information; and sending the first passive transaction signature authentication information to a blockchain to execute transaction operation corresponding to the passive transaction.
