Why buy a second-hand mobile phone with ID card and Alipay credit point?

In order to authenticate user information in real name.

Buy real names of second-hand mobile phones to prevent crimes of property infringement and theft. When selling or buying second-hand mobile phones or computers, you must show your ID card, and the operator will make detailed records. Second-hand goods must also be labeled with a unified "registration mark" before they can be "listed" after verification.

The public security bureau and other departments have joined forces to deal a heavy blow to the crimes of infringing property and selling stolen goods. Anyone who is suspected of collecting or selling stolen goods without telling his real name, address and identity will be detained in criminal detention.
