Playing around with it isn't very user-friendly but for professional developers it's dead-simple. I'm wondering if anyone has played with this and what the response has been from the older segment of their ward. Another unit in my Stake has been using it for a while and just displays the QR code on a sign with the usual passalong cards, etc. on tables on either side of the chapel. The QR code just goes to their website. While it seems like a fairly straight-forward approach, my guess is that it's not straight-forward enough for a high rate of adoption unless I'm grossly underestimating the expertise of the average ward nerd

Any experience you'd be willing to share (or pure speculation) is very much welcome!
