DVC chose the route where they start with a 3 cent plastic blank, paid someone to custom imprint each one, paid someone to mail it, and ended up spending about $1, most of which is postage. Had they started with an NFC card and done the same thing, it would have cost 10 cents more. That 10 cents, multiplied by the number of DVC members, is literally almost nothing in the grand scheme of things. But, the extra 10 cents would have allowed them to scan the card just like a magic band or KTTW card, and verify that the card was valid.
We went through this at my home owner's association. The simple wrist bands, which cost us $0.50 each with the imprint were easily duplicated. Most of the fakes came from one company, whose shade of yellow was just a bit off, and who didn't offer exactly the right font. Virtually all of these were created by members' children who wanted to give bands to their friends. We confiscated a lot of fake bands and told people to leave. The next year, we bought NFC wrist bands, encoded them, put a very complex logo on the face, told our members how security can scan a band and tell whether it's real or not, and had no unwelcomed visitors. The NFC bands were $0.40 each, because we bought thousands of them.
