The main reason we choose WP8 was the new Proximity API for reading NFC Tags.
I don't wanna write about how to read or write a NFC Tag but I just want to notify you an issue I encountered while developing.

So read a Tag brings an annoying system dialog.
I had to realize an app that reads tags during an event and does a check-in . So in a single page I want to read several nfc tags without any kind of interruptions.
Can I read a tag without seeing this damn alert that is literally ruining my UX? The answer is yes I can.
