Your mobile number should be enough for them. However this is a trend I’ve noticed so here’s what I do;

1. A polite message acknowledging that their safety and my safety/privacy is paramount.

2. I cover my address (except for suburb), my surname and licence number plus half my face on the photo. I photograph it and send it to them.

3. I also let them know they can see the real thing upon arrival but can’t make a record of it.

4. I also suggest they call my phone when I’m outside.

Usually this is enough for them to feel secure.
