Please refer to my first mail. There are three basic problems that I
1. You don't want to publish your private information
2. Manual exchange is difficult
Ridiculous! I give my phone to the other person and ask
them to dial my number and call me. Now we both have a
record of each others' phone numbers.
3. Face-to-face contact is not always available
I can't believe that I'm reading this in an email message.
Some people put their phone number in the signature block.
Others type it in when requested. Most mobile devices have
a way to sync a phonebook with a PC. Job done.
The proposed solution is the only one that addresses these three
Seems to me that you have only one real problem and we
can adress that (number 1 above) by simply doing nothing.
P.S. I did design a method vaguely similar to this for exchanging
contact information between mobile phone users that required the
support of the mobile network operator.
