How to send Bitcoin to my friend for his birthday?

I feel as if this might have been asked a lot but I also think it might be slightly circumstantial and Janice beneficial to ask especially considering how many people likely don’t know much about it.

I would like to send a friend some money for his birthday in the form of Bitcoin. I will withdraw from my exchange wallet. I’m not sure how the whole network functions and what the best way is. I often read and hear about the lightning network as opposed to the standard Bitcoin network. I’m just not as educated as some people are and would like to know what options I have.

Are there any apps I can use to do the whole QR code scanning thing? Can I connect my wallet? How easy is it for someone like me who doesn’t know every detail about actually transacting with the currency??

I have looked into getting a hard wallet but again haven’t educated myself enough yet.

Cheers guys.
