Whose code (card) should be used for medical treatment and drug purchases after "family pooling" is set up?

While money can be pooled, codes (cards) cannot be shared! Under any circumstances, the patient's own code (card) must be used for medical treatment and drug purchases. The "family pooling" policy pools the money in the personal account of the employee's medical insurance, not the code (card) itself. The principle of medical insurance is "enrollment by the individual, benefits for the individual." After family pooling, this principle remains unchanged. The insured still uses their own medical insurance for medical treatment and receives benefits according to the regulations.
