Relatives' cards have mandatory preconditions, so they must be associated with themselves first and authenticated by their real names. Among them, real-name authentication is related to relatives, and it is necessary to input relatives' names, ID cards and kinship, which will limit their age and gender. At present, only children under 18 and elderly people over 60 are allowed to bind.
The function of "family relatives management" mainly solves the problem of plain code and pseudo code. The original identity association mode is upgraded to two parts: personal association and relative association. First of all, limit a mobile phone number to only one host ID number. Secondly, bind relatives through kinship management, set kinship, cancel association and switch codes.
