what phone do you use, and what reader?

We use iPad mini's in L7 Cases with the Bluetooth Chip card reader at our farmer's markets and still have the mag strip reader on top in case someone has a non-chip card.  the iPad usually can last all day, we have it set to turn the screen off after a couple minutes.  I have an Anker battery in case they need to be topped off during the day.
