Forgot my card and book

Hi all,

We just moved over to the card system at our class and I've left today without my book and card. I could poss get home to get it before class but with the snow and the fact that I don't drive I'm not sure I have time after work to fetch it.
What happens if you turn up a class without it?

well , you get a new card and number , she has your details and you just destroy your old card

happened to me few weeks ago , cool idea with the card
