Using Samsung Pay which uses NFC on my S8 / Gear S3 here in Australia and it's pretty much instant. And I get a digital receipt on my device straight away, which is awesome. Protected by fingerprint, or code, so feels more secure than the Mastercard plastic with embedded NFC pay wave. Tap based pay has become ubiquitous in Australia, and I love it.
