This is excellent. Easy and automated (using the RFID tags in the pass itself, that’s scanned as you walk in the door), it’s quick and accurate.
As a bonus, I can rely on it to give me an email record of which talks I attended (so I can easily look them up, share with colleagues, etc).
I’m looking forwards to more conferences doing this…
