I have an iPhone 5 that I use to accept credit cards (I use PayPal Here with Square as a back-up). I am considering getting one of those cases with a built in battery for doing shows. I’m usually outside without electricity and don’t want to miss a sale due to not having any battery power. The problem is that most of those cases don’t seem to give enough access to the headphone jack to plug in a card reader.
Has anyone else tried a battery case or some kind of extension jack with the card reader? What would you recommend.
P.S. This is my first post here so I’m hoping I’ve done it correctly.
