So today I tried to swipe my card at WalMart and it said "card must be inserted". I asked what this meant and the first cashier did not know, they called over the supervisor who should us if you lift up the box where you swipe the card, there is a spot underneath were you could insert a card. I inserted my card and still didn't work.

Any thoughts? It has worked everywhere else. Trying to reach my $3,000 spend!
