For what it's worth, in Japan it's 100% standard to exchange virtual contact info via IR. Every time I witnessed a meeting of new acquaintances, people would automatically begin to form circles and exchange contact info. It's so cheap and effective, it really does make you wonder why it's so rare on American phones. The only electronic contact exchange I've ever witnessed in the US was between Googlers using 2D barcodes. I've never seen anyone use IR or Bluetooth.
