The registration database for each IETF meeting already contains email addresses of all attendees, presumably a superset of the blue-sheet signers. More technologically-advanced conferences and trade-shows use RFID or (a few years ago) mag stripes to avoid deciphering handwriting. The per-card cost is modest and since there are a lot of repeat attendees, we all just need our IETF "frequent flyer card". We used something like that for speaker identification at the microphone at ACM Multimedia 2004; the microphone had a BlueTooth-enabled RFID reader that transmitted the code to a data gathering host, which then displayed name and affiliation on a screen. The range of the card was a few inches.
