Why are you using QR Codes at YAPC::NA 2012?

Because its an easy and modern way to share information. Nearly all of the attendees will have either a feature phone or a smart phone capable of reading QR codes.

Will QR codes be the only way to get info at YAPC?

No. We'll, of course, share the URLs and other info contained within them as well.

Will QR Codes be optional on my badge?

Here's how you opt out of a QR Code on your YAPC::NA 2012 badge. 

  1. Get a marker (you can borrow one from a YAPC staff member)
  2. Take the cap off the marker
  3. Draw a zig-zag on your QR code
  4. Put the cap back on the marker
  5. Give the marker back to whomever you got it from

Of course you might also not want to do that since YAPC is a social conference and you might actually want to make it easy to share your info with other people at the conference.

Did you know that QR Codes are evil because  _____FILL_IN_THE_BLANK_REASON_____?

Welcome to 2012. The world's going to end this year anyway. Why do you care?

Interesting! I didn't even know there were people who disliked them.

Hmmm... would such zigzag be enough taking into account error correction features of QR codes?

I am glad to hear that there will still be regular text versions of links etc for those of us who haven't been able to justify the cost of a fancy phone. That said, I'd put a QR code on my forehead if it meant that more people would have my contact info when I finally enter the workforce (Ph.D. in hand).

I don't think they're "EVIL", but (1) they're useless and opaque to people like me who don't have, and don't want, a "smart" phone; (2) it's strange and slightly sad to see people (mostly marketroids) get so excited over what are essentially 2-dimensional barcodes.

Because its an easy and modern way to share information. that's true. QR Code are widely used in our daily life. and QR Code is my favorite one. the second one is code 39.
