I have to agree with Andy (or take it a step further) - that sounds terrifying. I think that very few people would want their phones gossiping about their identity to anyone nearby once the benefits and impact of it was explained to them. If you're going to make a proactive step to exchange contact information, your options are Audio, NFC, and Bluetooth. Or Bluetooth LE. And you're going to lose a certain segment of the population who have a phone but not the specific transfer mechanism you chose. And these technologies are opaque, sometimes scary. I think audio has a very compelling 'cuteness' to it. -tom _______________________________________________ Messaging mailing list [email protected] https://moderncrypto.org/mailman/listinfo/messaging
