Contactless phone payments

Can someone explain how these work? In order for this to work, which of these is true?

- your phone can be in sleep mode with the screen off
- your phone can be locked but with the screen on
- your phone must be unlocked with the screen on

Yes, I wondered if it actually had to be unlocked. I mean, it makes sense. Thanks, all.
