According to the embodiment, the smart wallet device 30 can support multiple wallets, one as a primary wallet and the other as a secondary wallet. Each wallet can manage one or more cryptocurrencies separately, so that users can choose to use one of them, and users can exchange Different wallets register different biometric characteristics.

FIG. 6 is a schematic diagram of a scenario using a smart wallet device.

The smart wallet device 30 has a power switch 305, so that the user can activate the smart wallet device 30 through the power switch 305. After startup, the wireless communication circuit is also activated at the same time, so that the user can operate the computer device (a mobile device in this example) to correspond to the communication Protocol scan, pairing connection.

As shown in the figure, the user can use a biometric technology (such as swiping a fingerprint) to activate a function in a decentralized application of the smart wallet device 30. For example, when connecting with the external computer device 60, the user may be required to swipe a fingerprint to authorize the connection. One of the applications is that when the computer device 60 (shown as a mobile device) is connected to the smart wallet device 30, the fingerprint identification is required to authenticate the user. The security authentication module in the smart wallet device 30 uses the secret of the specific cryptocurrency. Key encryption algorithm calculates verification data.

The preferred method is to encode into a QR code After that, as in step S105, the computer device and the smart wallet device are connected in the same way, and the wallet program is executed in the computer device. The user can operate the wallet program, as in step S107, using the scanning tool program to scan and display the information on the smart device. The QR code on the wallet device can automatically fill in the wallet address on the scanned device. When obtaining the wallet address, the user can be required to use the smart wallet device to perform identity authentication. In step S109, scan the fingerprint again. At this time, the wallet program can get through. The key of a specific cryptocurrency, that is, authorizing the wallet program to obtain transaction records on the blockchain.

After that, in step S111, the wallet program in the computer device is authorized to obtain the latest wallet data and complete the transaction of receiving currency. In step S113, the smart wallet device is connected via wireless communication means to transmit the transaction result and display the transaction result. On the display.

According to the above-mentioned embodiment of executing transactions through a smart wallet device, it can be known that users can perform currency transactions through a specific cryptocurrency website. If transferring to other people, they can fill in the transaction amount through the webpage or a specific APP, and then connect to the smart wallet. The device, after obtaining the authorization after authentication, can transfer the amount of a certain currency to others, and this message will form a record at each node on the blockchain. Conversely, if someone receives an account from others, the other person also transfers a certain currency amount through a wallet program, which is recorded by the node on the blockchain, so that the recipient can query the wallet address under verification after verification. Balance, the balance is derived from past transaction records after verification by nodes on the blockchain.

FIG. 11B shows a card pattern displayed on the screen of the computer device 12, indicating the smart wallet device graphic 123, which indicates the user to perform fingerprint authentication. A button 124 is provided below to provide the user with a confirmation message after completing the identity authentication.

Next, as shown in FIG. 11C, the transaction details 125 are displayed on the screen of the computer device 12. The details of the transaction cryptocurrencies are listed in the transaction details 125, or the equivalent fiat currency is included, and two buttons are provided: a transmit button 126 and a receive button 127. The send button 126 provides the user to decide to send the currency out; the receive button 127 confirms the receipt of the currency to receive a transaction amount set by others. After connecting to the smart wallet device and performing identity authentication, the transaction is completed after confirmation, and then authorized The computer device 12 obtains the transaction record about the wallet address from the blockchain, and can update the wallet information.

In FIG. 11D, the last wallet information is displayed on the screen of the display computer device 12, and may specifically include wallet information of multiple cryptocurrencies in the smart wallet device.

In summary, according to the smart wallet device described in the above embodiments, the smart wallet device is used to manage various resources operated by various application blockchain technologies, including cryptocurrency wallets, to manage cryptocurrencies, store keys, and execute decentralized accounts Decentralized applications such as this feature. Take the cryptocurrency wallet as an example, each wallet supports one or more cryptocurrencies, and the smart wallet device includes a display screen that can display one of the wallet addresses, provide others to scan to obtain the wallet address, or obtain the password at the same time. The verification data formed by the key calculation provides the docking computer device with the wallet data corresponding to the wallet address from the blockchain. The updated wallet data can be sent to the smart wallet device and the wallet information is displayed for user confirmation.

The content disclosed above is only the preferred and feasible embodiment of this creation, and therefore does not limit the scope of the patent application for this creation. Therefore, any equivalent technical changes made using this creation specification and diagram content are included in this creation application Within the scope of the patent.
