New membership cards were issued at the AGM. Each card has a barcode that will be scanned on attendance at each meeting and other club activities. This data will be merged into the Club's membership management system to track things such as number of attendees, quorum at meetings, whether the accounting system has recorded payment of course fees, and who has borrowed books from our library.
If you forget your membership card, you might just get a barcode on the back of your neck.
(Note from Andrew - I didn't post this, it was one of the other administrators masquerading as me! Due to a quirk of the system it's not possible to reset the author)
