I recently was at a Panera Bread, and when I put my Android phone (with NFC) onto the table, it immediately helpfully popped open tagwriter.
Turns out they didnt lock the tables' tags, so you could write urls and when people placed their phones down, had those urls open. (they used the tags for their food pager system)
A couple of weeks ago. It did take some work, it seems like there's a "sweet spot" that I had to hit, and some experimentation that required rotating the phone on the surface, but I was able to write google.com and then pop it open on my tablet.
