Businesses that scan your drivers license will then be able to start accepting it (chicken and egg problem). It can also likely be used for TSA. You can add your passport on Android, and it's not valid for international travel (and shows no personal info at all on the screen), but it activates the NFC chip and will transmit the passport info that way. TSA apparently have scanners at the agent that you can tap and the ID shows on their screen. I haven't tried it, but I've seen the scanners at every TSA ID checking station that I've been through for the last year or so.
Basically they're developing the ability to store it there, giving the possibility for it to be used in the future in some instances. It's the same for NFC payments actually. Just yesterday I was at the airport and was buying food at a restaurant. They said tap to pay was broken, chip only, so I had to dig through my bag to find my physical card. You still need to carry a physical card with you for backup purposes like this, same as with the ID.
