Section 5D. A gift certificate, as defined in section 1 of chapter 255D, sold or offered to be sold shall be valid for not less than 7 years after its date of issuance. The date of issuance and the expiration date shall be clearly identified on its face, subject to section 75C of chapter 266, or, if an electronic card with a banked dollar value, clearly printed upon a sales receipt transferred to the purchaser of the electronic card upon the completed transaction, or otherwise made available to the purchaser or holder of the electronic card through means of an Internet site or a toll free information telephone line. A gift certificate not clearly marked with an expiration date or for which the expiration date is not otherwise made available as provided in this section shall be redeemable in perpetuity. Once an expiration date has been reached, the issuer of the gift certificate shall not be subject to section 7. A purchaser or holder of a gift certificate which, by its terms, prohibits the purchaser or holder from adding value thereto and which has been redeemed for at least 90 per cent of its face value shall make an election to receive the balance in cash or continue using the gift certificate. A purchaser or holder of a gift certificate which, by its terms, authorizes the purchaser or holder to add value thereto and which has been redeemed in part, such that the value remaining is $5.00 or less, shall make an election to receive the balance in cash or continue using the gift certificate. A gift certificate with a zero balance shall be void.
