One of the things I tend to do when going to conferences & events is to generate a quick QR code with contact info.
If you have a smartphone (at least Android, Windows 7, or iPhone) you can use a barcode scanner app and scan this.
It’ll then load up my name, email, phone, etc (things I entered) and a memo that I included where I meet you and a couple additional notes.
