Perhaps we can have badges with QR codes that you can scan with the app on your phone to immediately add the person’s contact info to your address book. Or with precise enough GPS locations (that we’ll have because of the walking meeting idea) we can have an algorithm automatically determine which people you (probably) talked to during the conference based on proximity, setting, context, and length of contact. This could also be done with simpler sensors that just detect proximity.
