if I have a voucher, what are the two "states" of the voucher. Like is it "free" or "unused" when I haven't used it yet and "used" or "redeemed" when I used it?
"Susi doesn't have her tickets yet, but she has an unused (?) voucher."
"Susi got her tickets with the voucher, the voucher is now redeemed (?)."
It's actually hard to put it in an example sentence, as I need a voucher object in software development. Maybe it's more clear this way:
Voucher.State = Used; Voucher.State = Free;
Thanks for your help.
