On Fridays, my friends and I love to go see movies.  Sometimes, we stay inside the house, and rent movies.  One of the places we like to go to has a machine full of movies called Redbox. We go to this store, and use the machine to rent movies.  When you go up to the Redbox machine, you just press "Rent Movies",  and then it shows you movies you may like.  They even have categories you can pick from, like comedy, drama, suspense, and even scary ones.  Usually, my friends and I pick comedy movies when we watch movies together.  So, once you pick a movie, then you press that button for the movie, and it let's you use your bank card to pay for the movie.  The machine records your card information from your bank, so that whenever you bring it back, it will charge you for how many days you kept it.  It is very cheap to use, and very nice. 
Question: How did they pay for the movie?
