How do I connect my Square Reader to an iPhone 8?

I have a customer who wants to buy tickets through Square.  I have used it with moderate success using an iPhone 6 Plus.  Now I have a new iPhone 8.  How do I connect the Square Reader to an iPhone 8?

You use the adapter that came in the box.  all iPhone 7, 7 plus, 8, 8 plus, and iPhone X came with a lightning to headphone jack adapter in the box.  If you lost that one they can be bought for usually less than $10 at best buy/apple store/amazon etc
