I am looking into how to use Tap to Pay on iPhone. The official announcement said it was available through the point of sale API, but is there already a document somewhere that describes how to set that up?
At this time the Tap to Pay is in an early access. Space in Square’s Early Access Program for Tap to Pay on iPhone is limited. If you’re interested in learning about Square’s Early Access Program for Tap to Pay on iPhone can visit squareup.com/get/tap-to-pay for more information.
