On one of my newsletter messages that I received today was a link to a quilt blog that had some information regarding QR codes. I have seen them before and never really gave them much thought. It seems that you can scan the codes with your phone or iPad or BlackBerry or whatever, and if you can connect to the internet, it will take you right to the site. I downloaded a QR reader this morning, then when we were at Sam's, I found a box with a QR code and sure enough it took me right to the item's website.
I did not have a reader on my iPad, but I was able to find a reader in the AppStore. The one I downloaded was not a free one, but it only cost 99 cents. There were Free ones available, but the one I chose had better feedback. Anyhow it is working fine so far. The code generator was free from one of the links that came up in my Google search.
I'm going to try to get back to posting more frequently than I have in the past couple of months.
