QR Codes

[M. E. Petrich]

Hi Liz,

Have you figured out what the specific problems are with the QR codes? 
For example are these QR code providers also applying another
url-shortening or redirecting url? Is it those urls which are expiring?

Since you are already using bit.ly for url shortening, have you considered
also using them for QR codes?

If you don't get answers here, you might find out what institutions of
similar size and resources are using QR codes and contact them directly.
