I am trying to wrap my head around these. How can they be used in a way that's better than other methods? For example, if I wanted to do a bunch of things when leaving the house, wouldn't it be easier to put a tasker widget on your homescreen instead of looking for a tiny tag on the wall and precisely touching the phone to it? They might seem to make sense for business. Stores could place tags on signs next to each product and it would launch a link to a website. Even still, you could do the same thing with a barcode scanner and you wouldn't have to be that close to it.
