alt Hacker News> Related: there is a known scam where someone will ask for payment by things like Ebay gift cards. To "prove you have the card", you are asked to read off just the last few digits of the card - which unbeknownst to the intended victim is actually all that is needed to redeem the card.
I'm not following. If things have gotten this far, the victim has already been duped into buying the card and intends to send it to the scammers anyway... ?
But also, how could the card possibly work that way? What are the other digits even for; and wouldn't they quickly run out of valid "last few digit" combinations for issued cards?

Yes, the mark has essentially fallen for the scam, but not yet arrived for the goods... which don't actually exist.

Exactly why I hate that Ebay uses their insipid coding schema. I'm not explaining why they do it, because I can't.
