There is an expiry date on the Glo 17 cards, why can’t you just show when the card finishes?

The expiry date on the Glo 17 shows when the actual card expires, which is the card holder’s 19th birthday, after that the card won’t accept any top-ups. We don’t print an expiry date on the cards for the value because they are re-useable and you can keep them for years.
