How does a Health Card function in case of policy renewal?

Health Card is a proof of purchasing a policy. It holds a unique policy number. At the time of renewal, your policy is renewed on the basis of the policy number stated on the card and then, after renewal, a new card is issued so that an insured can avail the associated facilities and benefits for extended time duration.
