In this embodiment, the collection information is input by the user through the input keyboard or the input interface of the collection device, and the collection information at least includes a collection amount; the payment information at least comprises a payment mode, wherein the payment mode is the currency type of the currency currently used for payment; when the payment mode is payment through electronic money, that is, when the money type is electronic money, the payment information may further include at least one of payer information, payment platform related information, bank information of money to be paid out by the payer, and payment verification information of the payer; when the payment is made by digital currency, i.e. the currency type is digital currency, the payment information may also include payer information, such as a public key certificate of the payer.
The electronic money is money paid by an electronic way, and the electronic money is money which is paid to an issuer of the electronic money by using a network banking service of a bank to store value and pay quickly, and the electronic money enables the payer to conduct transaction in an electronic form through a medium (a two-dimensional code or hardware equipment). Correspondingly, the payment platform comprises a third party payment platform and a bank payment platform, wherein the third party payment platform can be a payment bank, a WeChat, a cloud flash payment and the like, and the bank payment platform comprises a financial IC card, an official mobile phone bank of each commercial bank and the like.
The digital currency is legal currency in a digital form, and particularly in the people's republic of China, the digital currency refers to legal currency issued by China's banks, and the digital currency is universal currency which is equivalent to paper currency and metal cast currency issued by China's banks.
The digital money may be stored in a hardware digital wallet of the cash register or in a digital money management server, for example. In particular, digital money in a hardware digital wallet may be transferred by a cash register to a digital money manager server.
The processor receives the collection information input by the collection party, acquires the payment information of the payment party, acquires the payment mode in the payment information, acquires the collection party information and the bank information of the collection party for receiving the money when the payment mode is payment through electronic money, namely, the type of the money used for payment is electronic money, generates a transaction request according to the collection amount, the collection party information, the bank information of the collection party for receiving the money and the payment information in the collection information, sends the transaction request to a first server, acquires the money from a bank of the payment party for paying the money according to the transaction request, transfers the money to a bank of the collection party for receiving the money, completes money transfer, and sends prompting information of transaction completion to a terminal device and a collection device corresponding to the payment party after the money transfer is completed.
When the payment mode is that the payment is made through the digital currency, namely, the type of the currency used for payment is the digital currency, the processor receives the digital currency sent by the payer, then performs transaction verification based on the digital currency and the collection information, receives the digital currency sent by the digital currency management server after the transaction verification is passed, takes the digital currency as the target digital currency, and stores the target digital currency in the hardware digital wallet.
In the technical scheme disclosed in the embodiment, after receiving the payment information input by the user, the payment device acquires payment information, determines the currency type of the payer for payment according to the payment information, and executes the payment methods corresponding to different currency types to collect corresponding money, thereby achieving the effect of supporting the payment methods based on electronic currency and digital currency at the same time.
Illustratively, the step S30 further includes:
step S31, obtaining digital currency;
step S32, obtaining the current network state;
step S33, when the current network state is an unconnected state, performing preliminary verification on the first digital signature of the digital currency;
step S34, taking the digital currency which passes the preliminary verification as digital currency to be verified, and storing the digital currency to be verified into a hardware digital wallet;
step S35, generating transaction running water;
step S36, when network connection is detected, generating a transaction verification request based on the digital currency to be verified and the transaction flow, and sending the transaction verification request to a second server;
and step S37, receiving target digital currency returned by the second server based on the transaction verification request, and storing the target digital currency.
Specifically, the step S33 further includes: a first digital signature of the digital currency is verified from an issuer public key of the digital currency.
Because each digital currency has its corresponding monetary amount, the payer will send at least one digital currency for payment transaction when making a payment; the processor obtains the current network state after receiving the digital currency sent by the payer, and obtains the public key of the issuer in the hardware digital wallet when the current network state is in an unconnected state, wherein the issuer is the issuer of the digital currency, namely the central people bank, the public key of the issuer is the public key of the central people bank, and the corresponding first digital signature is a hash value obtained by signing the digital currency by using the private key of the issuer. The processor performs preliminary verification on the digital currency according to the public key of the issuer, namely, the first digital signature of the digital currency is verified through the public key of the issuer, and when the first digital signature is successfully verified, the preliminary verification of the digital currency is passed; upon failure of the first digital signature verification, the preliminary verification of the digital currency fails. The second server is the digital money management server.
When the digital currency passes the preliminary verification, the processor takes the digital signature passing the preliminary verification as the digital currency to be verified, and stores the digital currency in a hardware digital wallet, and then generates transaction running water based on transaction information such as the collection amount, the collection party identification, the payment information and the like in the collection information, and stores the transaction running water in a memory.
When the processor detects network connection, a transaction verification request is generated based on digital currency to be verified and transaction running water, the transaction verification request is sent to a digital currency management server, so that the digital currency management server verifies the digital currency to be verified after receiving the transaction verification request, after the digital currency to be verified passes verification, the collection amount is obtained according to the transaction running water, the actual payment amount is calculated according to the digital currency to be verified, the target digital currency is obtained according to the collection amount and the actual payment amount, and the target digital currency is sent to a payee. After the processor receives the target digital currency, the target digital currency is stored in a hardware digital wallet.
Illustratively, assuming that the payee needs to collect 68 yuan and the amount of digital money paid by the payer is 100 yuan, at least one target digital money is acquired in the digital money management server, and the amount of money of all the target digital money is added to 68 yuan.
Specifically, after the step S33, the method further includes: and sending prompt information to a payer when the primary verification of the digital currency fails.
When the primary verification of the digital currency fails, namely when the first digital signature verification fails, the processor sends prompt information that the digital currency is invalid to the payer, so that after the payer receives the prompt information, whether the digital currency used for payment is replaced or not is judged according to the prompt information.
In the technical scheme disclosed in the embodiment, the issuer public key is acquired during offline payment to verify the validity of the digital currency, so that invalid digital currency is prevented from being received, and the validity of a transaction result is ensured.
Optionally, the step S30 further includes:
step S38, when the current network state is a connection state, generating a transaction verification request according to the payment information and the digital currency, and sending the transaction verification request to a second server;
and step S39, when receiving the target digital currency returned by the second server based on the transaction verification request, storing the target digital currency.
When the current network state is acquired as a connection state, the processor directly generates a transaction verification request according to the payment information, the collection amount in the collection information and the received digital currency, and sends the transaction verification request to the digital currency management server, so that the digital currency management server verifies the digital currency after receiving the transaction verification request, acquires the collection amount according to transaction running water after the digital currency passes verification, calculates the actual payment amount according to the digital currency to be verified, acquires target digital currency according to the collection amount and the actual payment amount, and sends the target digital currency to a collection party. After the processor receives the target digital currency, the target digital currency is stored in a hardware digital wallet.
In the technical scheme disclosed in the embodiment, the current network state is judged, and when the network state is the connection state, the digital currency is directly verified through the digital currency management server.
Optionally, as shown in fig. 3, in a second embodiment of the money collecting method according to the present invention, before the step S30, the method further includes:
step S40, verifying a second digital signature of the first public key certificate according to the public key of the issuer of the digital currency;
and step S50, after the second digital signature passes verification, a second public key certificate of the payee is sent to the payer, so that the payee can obtain payee information according to the second public key certificate and send digital currency to the payee.
In this embodiment, the foregoing payer information may be a first public key certificate of the payer, where the first public key certificate is a public key authentication certificate generated by signing a public key of the payer with a private key of an issuer; correspondingly, the second public key certificate is a public key authentication certificate generated by signing the public key of the payee with the private key of the issuer.
After the processor acquires the payment information, acquiring a first public key certificate in the payment information, verifying a second digital signature in the first public key certificate through an issuer public key, and after the second digital signature is verified successfully, transmitting a second public key certificate to a payer; after receiving the second public key certificate, the payer verifies the digital signature in the second public key certificate according to the public key of the issuer, and sends digital currency for transaction to the payee after the digital signature in the second public key certificate is successfully verified.
In the technical scheme disclosed in the embodiment, the public key of the issuer is obtained to verify the public key certificate of the payer, so that the security of the transaction process is ensured.
Optionally, as shown in fig. 4, in a third embodiment of the money collecting method according to the present invention, the step S10 further includes:
s11, when the insertion of a payment card is detected, reading payment information in the payment card; or alternatively, the first and second heat exchangers may be,
and step S12, when the two-dimension code payment is scanned by the camera device, acquiring payment information in the two-dimension code payment.
In this embodiment, the payment card may be a financial IC card for electronic payment or a digital money wallet IC card for digital payment.
When the processor detects that the payment card is inserted, the payment party information recorded in the payment card and the currency type for payment are acquired through the card reading device; or the processor can scan the two-dimension code through the camera device and then acquire the payment information recorded in the two-dimension code.
In the technical scheme disclosed in the embodiment, the convenience of transaction is improved by setting the acquisition modes of various payment information.
