An easy-to-scan smart payment bracelet based on blockchain technology

Abstract

The invention relates to an intelligent payment bracelet based on block chain technology that is easy to scan, including a main body, a watch strap and a cover plate, a processor and a memory are arranged in the main body, and a telescopic mechanism and a defogging mechanism are also arranged in the main body. The mechanism includes a telescopic assembly and a display screen, the telescopic assembly includes a drive unit, a connecting block, a connecting plate, two telescopic frames and at least two connecting rods, and the defogging mechanism includes a moving assembly, a swing assembly, two cleaning blocks and two lifting assemblies , the lifting assembly includes a first motor, a turntable, a connecting line, a positioning rod, a slider, a spring, and a limit block. The smart payment bracelet based on blockchain technology that is easy to scan extends out of the display screen through a telescopic mechanism, thereby more It is convenient to scan the display screen, which improves the convenience of the smart payment bracelet, and wipes the water mist inside the bracelet through the defogging mechanism, making the smart payment bracelet easier to observe and improving the practicability of the smart payment bracelet.

Description

technical field [0001] The invention relates to an intelligent payment wristband that is easy to scan based on block chain technology. Background technique [0002] Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes intelligence composed of automated script codes. A new distributed infrastructure and computing method that uses contracts to program and manipulate data. It is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. [0003] Blockchain technology has a high degree of data security and is widely used. [0004] The smart payment bracelets of the prior art generally adopt traditional data encryption methods, which easily cause data loss. Moreover, the smart payment bracelets of...

Problems solved by technology

[0004] The smart payment bracelets of the prior art generally adopt the traditional data encryption method, which is easy to cause data loss, and the smart payment bracelet of the prior art needs to turn the screen to a position parallel to the code scanner when scanning the code for payment. state, the convenience of the existing smart payment bracelet is greatly reduced, not only that, the inside of the existing smart payment bracelet is easy to form water mist, resulting in unclear display, which greatly reduces the practicability of the existing smart payment bracelet reduce
