TIL you can use #ApplePay on a non-Apple device as long as you have another #Apple device with a camera.

Example: I was paying for a little Voicemod Pro on my gaming PC to try it: https://www.voicemod.net

The payment process will display custom QR code you scan with an iPhone or iPad. Finish Apple Pay there, Voicemod website updated on PC, and Bob's my uncle. Smooth experience.
