Glad to hear that a NFC library will be available!
My application will use NFC to log the location. This is for QC (Quality Control) purpose. A NFC-tag is mounted at the wall in a room, the user will get displayed a form based an the info from the tag and has to check and answer the items (questions) on the form. The data is then transfered to an FTP-Server. With this app, in one case, the condition of the room after cleaning is recorded (food industry).
The tags may be also used in security or to record the condition of rental item returned. The form is automatically based on the info read from the NFC-tag. So the form is very flexible.
The NFC-Tag will make sure, that the user may not fake the checking and the data can be correctly processed in the Desktop-Application.
