Can I show ID through phone?

Could you please clarify for me, is it possible to verify my identity for cryptocurrency transactions or other financial purposes solely through the use of my phone, without the need for any physical documentation? I understand that security and compliance are paramount in this industry, so I'm keen to understand if this option is available and how it might work. Additionally, are there any specific apps, platforms, or services that you recommend for this purpose? Thank you for your time and assistance.
