Problems solved by technology

[0003] 1. It is impossible to identify which shopping cart is the last one. The patent application number "201810378628.3" will only display the unlock code of the shopping cart locked by the QR code scanned by the software, and does not care whether the shopping cart is connected end to end The last one of a group of shopping carts, so it is possible to unlock the middle of a group of shopping carts connected end to end

[0004] 2. The charging problem of the shopping cart lock. The shopping cart locks described in the invention patents with application numbers of "201810027246.6" and "201810378628.3" each require an independent battery, which needs to be charged when the battery is used up. Charging the car will be a new task for the management of the supermarket, which is very troublesome, and after the battery has been used for a period of time, the power may not be enough to support the shopping cart for a day. cause unnecessary trouble

[0005] 3. Invention patent applications with application numbers "201810027246.6" and "201810378628.3" need to install a dedicated APP to use, which limits the user's choice. Currently, users generally use WeChat or Alipay when using code scanning software. Adding a new software not only increases The operating cost of the supermarket also increases the unnecessary actions of the user to install and use the software

Users need to install a specific APP when entering each different supermarket, which is very inconvenient

[0006] 4. Invention patent applications with application numbers "201810027246.6" and "201810378628.3" require the user's smart terminal to be connected to the shopping cart lock. When multiple shopping carts are locked at one location, the user needs to operate the smart terminal in multiple It is very troublesome to find the specified shopping cart lock in the name list of WIFI or Bluetooth, and the patents with application numbers "201810027246.6" and "201810378628.3" do not describe a quick way to find the name of the specified shopping cart lock

[0008] 6. The invention patent applications with the application numbers "201810027246.6" and "201810378628.3" all require a wireless communication module, which is expensive, and also requires an independent battery, battery management, and power-out reminder function. In the actual use environment, there is also a special Personnel are responsible for charging, hardware costs and usage costs are high
