This does not act as a hotel key for some reason
At first I assumed this was a a multifunction card used for credit as well as other typical card functions.  When staying at a Comfort Inn in Pittsburgh, I tried to use this to unlock my hotel room door.  I must have inserted the card into the face of my door half a dozen times before realizing Amazon had ripped me off.  I went to the hotel’s front desk, borderline hysterical, and said “There must have been some kind of mistake!”  My handler found me and told me everything was alright and it turns out that these actually aren’t used for opening hotel room doors.  It turns out the hotel gives you a free card every time you stay with them, but when you check out, it doesn’t work anymore.  However, I was able to buy products from Amazon using the $25 I had already spent on the card.  That made me feel better.  Thanks Amazon!
