(b) A donor or other individual authorized to make an anatomical gift under section 4 may make a gift by a donor card or other record signed by the donor or other individual making the gift or by authorizing a statement or symbol indicating that the donor has made an anatomical gift to be included on a donor registry. If the donor or other individual is physically unable to sign a record, the record may be signed by another individual at the direction of the donor or other individual and such record shall:
