Technical Field

The invention relates to the technical field of digital currency transactions, in particular to a digital currency label code plate activation device and an activation method.

Background

The 'touch and collision' is a payment and receipt function of digital currency, and the touch and collision between the mobile phone and the NFC tag is one of the expressions. The digital currency collection number plate of the merchant can be integrated with a 'touch-and-dash' label, so that the payment by scanning the number of the digital currency is realized, and meanwhile, a 'touch-and-dash' payment mode is supported.

At present, no security activation tool for the 'hit-hit' label code plate of the digital currency exists in the market, and the 'hit-hit' label code plate is usually activated by using a mobile phone. When the mobile phone is used for activation, a user needs to prepare a mobile phone with an NFC function and download software for reading a collection code, the collection code is read by scanning the software, the user manually copies the collection code, then an NFC tool of the mobile phone is opened, the collection code is pasted into the NFC tool, and then the collection code is written into a label code plate.

When the collection code in the label code plate is verified, the collection code needs to be read through an NFC tool of the mobile phone, and then whether the collection code in the label code plate is the same as the collection code stored in the mobile phone is manually checked.

If the label code plate is to be locked, the NFC tool of the mobile phone is required to have a locking function, and the NFC tool with the locking function is usually paid for payment.

Through the operation of judging whether the money is legal or not, the method provides guarantee for writing the money receiving code into the digital money label code plate, and avoids writing the wrong money receiving code into the digital money label code plate.

In one embodiment, the wireless read/write module 30 may perform read/write operations on the digital currency label number plate based on the APDU command.

In a specific embodiment, the wireless read/write module 30 may first search for the digital currency tag code card, and when the digital currency tag code card is searched, the wireless read/write module 30 writes the money receiving code into the digital currency tag code card based on the APDU command, or the wireless read/write module 30 reads the money receiving code from the digital currency tag code card based on the APDU command, and further, the comparison module 40 determines whether the money receiving code read from the digital currency tag code card is the same as the digital currency receiving code stored in the storage module 20, and if so, the locking module 50 locks the digital currency tag code card based on the APDU command through the wireless read/write module 30. Thereby completing the activation of the digital currency label combination.

The receiving code data is directly written into the digital currency label code plate through the wireless card reading module, so that the complicacy of manually copying the receiving code and writing in through an NFC tool in the prior art is avoided.

The wireless read-write module directly reads the cash register code in the digital currency label code plate and judges whether the cash register code is the same or not, thereby overcoming the defect of manual checking in the prior art. In wireless communication, the APDU command is usually used, and the invention still adopts the command without additionally increasing the development cost. And under the condition that the two payment codes are judged to be the same, the locking operation of the digital currency label code plate can be executed, and the problem of cost waste caused by the fact that payment is needed to be carried out for locking in the prior art is further solved.

In one embodiment, locking the digital currency label code plate may include: and setting the digital currency label code plate to be in a read-only mode, or encrypting the writing operation of the digital currency label code plate. Thereby ensuring the safety of activating the label code plate.

For example, the writing operation of the digital currency label code plate is locked and changed into a read-only mode, at the moment, the label code plate can not be written with any data any more, and when the cash register of a merchant is changed, the merchant can be reactivated/initialized by returning to the factory for processing or replacing the cash register plate which is touched once. Or, the writing operation of the digital currency label code plate is encrypted, a password can be set and written into a password area of the label code plate, the password area cannot be accessed, when the collection code of the label code plate is required to be rewritten by touching, the password needs to be input for authentication, and the writing operation cannot be performed after the authentication fails.

In an embodiment, the digital currency tag code card may be an NFC tag code card chip, that is, an NFC "touch-and-touch" chip, and then the wireless read-write module 30 may be a module with an NFC read-write function. Therefore, the functions of searching the label code plate, writing and reading the collection code, comparing the collection code and locking the label code plate are completed.

The NFC 'one-touch-one-touch' chip can comprise three parts: radio frequency analog circuits, digital logic circuits, and non-volatile memory (EEPROM), which may be organized in 4 bytes as a page. The READ command uses FAST _ READ, and the command can be used to READ data of N pages consecutively, and the parameters include two of start address and end address, and address 256 pages at most, each Page occupies 4 bytes (see fig. 3). A write command, which includes two parameters, a block address and block data, writes 4 bytes of data in the block address (refer to fig. 2).

When the locking operation is executed, the static locking bits of the EEPROM of the NFC 'hit-and-hit' chip can be set to be specified data through a writing instruction, so that the locking of the writing operation of the tag code plate 'hit-and-hit' is realized, and the mode is changed into a read-only mode. The 4-byte Password (PWD) and the 2-byte password authentication response (PACK) can be stored in the password area of the EEPROM, so that the writing operation of the tag code card of 'hit-hit' is encrypted.

In one embodiment, the digital currency label code activation device of the present invention is integrated within a POS. The POS may be used to activate a digital currency label combination.

When the digital currency label code card needs to be activated, a POS machine is used for scanning a collection code and judging whether the collection code is legal or not, whether information is complete or not and the like, and if the collection code is legal, the POS machine stores the collection code; then, the money receiving code needs to be written into a digital currency label code plate in a mode that the money receiving code data is wirelessly written into a 'touch-touch' NFC chip through a wireless read-write module of the POS machine; and finally, locking the digital currency label code plate to ensure the transaction safety, reading a cash collection code in the digital currency label code plate in an NFC (near field communication) wireless mode through a wireless read-write module of the POS machine at the moment, comparing the cash collection code with the cash collection code stored in the POS machine, and if the cash collection code and the cash collection code are the same, sending a locking instruction to the digital currency label code plate through the wireless read-write module of the POS machine, wherein the locking instruction can enable an EEPROM (electrically erasable programmable read-only memory) of the digital currency label code plate to be read only, and can write a password into the EEPROM and the like.

From the operation process, the activation device of the digital currency label code can execute the activation operation of the digital currency label code, the operation is very convenient, the whole operation process does not need manual judgment, the accuracy is ensured, the locking operation executed at last ensures that the data of the cash register code is not rewritten by other tools, and the safety of cash register is ensured.
