Can the old social security card still be used after the new social security card is activated?

Legal analysis: after the new medical insurance card is activated, the old medical insurance card automatically becomes invalid and cannot be used. The old medical insurance card can continue to be used until the new social security card is activated. After the new medical insurance card is activated, the insured should not continue to use the old medical insurance card, because when the bank computer system detects that the old medical insurance card is still in use, it will not issue an operation instruction to transfer funds.
