wiki has a few bar code option http://en.wikipedia.org/wiki/Barcode#Matrix_.282D.29_barcodes

@rich-brooks – I think there was something called a smart tag, where you don’t need to scan a code, just scan it by taking a picture of it. No need to download a program to translate it.. however, If I remember in my research it was a very expensive option for the small business community. However, some of the new smart phones and tablets would have it, I would have to look back in my notes on this if you really want to know.

I’m with Cynthia – augmented reality will eventually replace QR codes. But especially for small businesses, this will still take a while to happen because of cost reasons.

AR can be cost prohibited but I think like everything else that could change in the future.

I don’t believe QR codes are going anywhere for a while. Most people and businesses don’t know how to use them. I believe that could be the main problem. 

I have one on the back of my business cards. When I hand them out, folks scan the code and my contact info is automatically entered on their smart phone as a new contact. It has my name, company name, position, web address and phone numbers. Sure beats typing it all in – plus cards aren’t always that effective.

absolutely amazing, never heard of augmented reality, though not surprised @dhsllc
