Say you want to check your mail at https://mail.google.com/ - if you do not know if you talk to the entity owning real google.com, then you risk talking to a man in the middle attacker - which may snatch your password pretending to be mail.google.com. So with encryption without identity you end up talking encrypted to anyone wanting to pretend they are mail.google.com.

Or do you have a solution for preventing man in the middle attacks?

I dont see how you can separate encryption and identity - if you do not know who you are talking to then encryption has no value?

Lets say a man in the middle says - Im your bank, please talk encrypted with me. Then the man in the middle just repeat what you say to your bank until you are logged in.

The download certificate on first meet might provide some security, but would make it difficult to do business with unknown entities.

In my world I have to pay about $10 to use a check (not that I used one ever in my entire life).

Paying by bank to bank or debit card is free.

What pricing model the future has is not set in stone.

If programming languages was written in plain words we wouldn't need programmers, but the secret order of computer programmers refuse to do it that way - simple programming is not possible they claim. What they really are afraid of is the fact that normal humans (non programmers) could just diff the text to look for bugs and even make their own software.

PS! A lot of the people here at slashdot.org are members of this secret order so they will probably mod me down and try to shut me up - BUT justice will prevail.

You could have e-Ink technology behind the lcd tech. When you turn off the lcd layer you would reveal the e-ink screen.

e-Ink particles layer -> LIGHT -> lcd layer

or if you had semitransparent particles:

BACKLIGHT -> e-Ink particles layer -> lcd layer

I really cannot see what technology is used from those blurry pictures.
