Back in the 1990's they had membership cards with an expiration date, and they then issued new ones when the date approached. They are apparently renewing that concept again. What is on the membership card has nothing to do with when your ownership interest ends, which for SSR is 2054. They have not explained why they are now reinstating membership cards that expire and then are replaced with new ones, but some have reasoned that it is likely because they now have a lot of ex-owners who still have, and could wrongly use for discounts, membership cards with no expiration date.
