Does it matter if Harbin Bank's social security card is replaced by ICBC?
No, because the social security card can be exchanged for a bank, the use of the medical insurance card is generally not affected after the social security card is exchanged for a bank. If the social security card and the medical insurance card were used separately in the past, the social security card exchange for a bank will not affect the change of the relevant information of the medical insurance card, so the social security card exchange of Harbin Bank for ICBC has no effect.
