I feel like the typing/confirmation issue could be solved by adding a QR code generator to your email app, and having them scan the QR code on your phone to share details.

You already have your phone out, and they probably have to take theirs out to confirm, so it doesn't add anything that doesn't already exist. But this application of QR Codes saves typing in a good way.

Assuming the other person has a QR code reader app and knows how to use it.

And if you want their info vs giving them yours, then they also have to know how to get their address displayed as a code.

Technically no problem, in practice I wouldn't expect it to work.

Facebook used to have this feature but I can't find it anymore. I only found out about it after meeting someone in Tokyo and have never been able to find the feature since which leads me to wonder if it's geofenced.
