That assumes every LEO, bodega, grocery store, etc. goes out and buys the terminals to read these things though. Assuming LEOs you encounter will never just say "sorry, my reader is broken, go ahead and unlock your phone so I can bring it back to my car and type in your info to look up your license" feels naive, especially for folks with darker skin tones.
I agree it's possible to present your ID without unlocking your phone, but is it likely?
