The second is to input the child's identity information into the adult's health code and replace the ID card with the health code. On our side, you only need to show your health code to do nucleic acid now, because your personal identity information has been bound in the health code, so you can show your health code and give your name, which can be used as the basis for nucleic acid registration in the future. Children don't have WeChat, and adults can also receive health codes. Similarly, if a child needs to do nucleic acid, he only needs to show his health code. In fact, the medical institution does not require you to provide your ID card, but you need to have an ID card to let him know who you are doing nucleic acid for. Of course, the management requirements of each place are different, but I think for the convenience of operation, most places allow health code scanning and registration as nucleic acid detection. Therefore, you can also give your child the health code you applied for first, and then do nucleic acid testing based on it.
Of course, if you feel that neither is particularly convenient, you can apply for an ID card for your child in time. It is also very convenient to apply for an ID card now. If it's urgent, you can get it in two or three days. If it's not urgent, you can get it in a week or two. Identity card is not the only information to prove a person. For example, if a child has no registered account, then his birth certificate can prove his identity. If the child has registered an account, the account can also be used as proof of identity.
