Pay iOS Devices Don't 'Bonk'
Unlike the dopey first generation RFC cards, there's no 'bonking' with Pay iOS Devices. You put the device in proximity to the RF field and push a button on the device. All done. On the iPhone you push the fingerprint sensor. On the Watch, if you've entered your PIN, you press on the watch face.
It will be a happy day when the cruddy, insecure first generation of RFC chips is dead and gone.
