Problems with swiping card on iPad

[jdsergent]

I am attempting to use my magstripe card reader on my iPad Air 2. However, the only option for payment is for the customer to either pay with cash or I have to manually enter in the credit card number. How do I get the option to show for swiping a card?

All you have to do is plug the swiper into the headphone jack and Square register should see it.  Try restarting the ipad and or deleting and reinstalling the Square Register app (all your imformation is safe in the cloud and will be there when you sign in after reinstalling).
